Features and Benefits
The Mark 3 possesses many unique features and benefits; however,
there are three distinct features that differentiate it from other ANSI
pumps. These features are the power end designs, the Mark 3
reverse vane impeller, and the SealSentry seal chambers. Below is
a brief summary of these features with their corresponding benefits.
Power End Designs
Micrometer impeller adjustment
Shaft design and options
• Wider bearing span
• Larger bearing size for Group 2
• Friction welded design provides optimum corrosion resistance
and strength
Lubrication
• Oil bath (standard)
• Regreaseable
• Greased for life
• Oil mist
Durco ANSI3A Option
• Fast, accurate impeller clearance setting
• No need for cumbersome and time consuming use of dial
indicators or feeler gauges
• Maintains shaft concentricity which improves seal life
• Superior to jackscrew design because of accuracy, speed and
uniform bearing loads
• Superior shaft rigidity for improved bearing and mechanical
seal life
• Broad material options to meet all corrosive applications
• No special shafting required for high radial load applications
• Tailor lubrication method to plant standards for long, troublefree bearing life
• Clean room assembly to prevent bearing housing contamination
• VBXX “Vapor Block” bearing isolators that keep lubricant in and
contaminants out
• Lifetime warranty
Mark 3 Reverse Vane Impeller
Low, predictable seal chamber pressure and thrust loads
Low NPSH required
Rear cover plate is wear surface
Repeatable performance
In-shop impeller adjustment
• Improved mechanical seal life
• Improved thrust bearing life
• More flexibility in pump selection
• More flexibility in system design
• Rear cover replacement is much more economical than casing
replacement
• One setting controls the critical parameters of performance,
efficiency, seal chamber pressure and thrust/axial loads
• Takes full advantage of back pullout feature
• Impeller and component mechanical seal settings can be made
in the shop rather than under adverse field conditions
SealSentry Seal Chambers
• Provides best sealing environment for each specific application
• Self-venting, self-flushing, self-draining
• Extends seal life by purging heat, solids and vapors
• Permit use of single seals in many services where dual seals
with external flush were required
• Can eliminate flush plans for many single seal applications
• Extend mechanical seal life

Configurations
In addition to the ANSI standard pump configurations, the Mark 3
is available with specialty wet ends for specific applications.
These include:
• Mark 3 Sealmatic – dynamically sealed pump that eliminates the
need for conventional mechanical seals
• Mark 3 Unitized Self-Priming – used for pumping from sumps or
liquid sources located below the pump centerline
• Mark 3 Recessed Impeller – used to pump liquids that contain
large solids or stringy/fibrous materials
• Mark 3 In-Line – pump suction and discharge located on the
same centerline, pump oriented in vertical position
• Mark 3 GRP – solid polymer wet end for pumping highly
corrosive liquids
• Polychem S – fluoropolymer lined pump that uses conventional
mechanical seals
• Guardian Magnetic Drive – used where no process leakage can be
tolerated
• Polychem M – magnetic drive fluoropolymer lined pump

Shafts (see Table 2)
Solid shafts are recommended
over shaft sleeves because they
reduce the harmful effects of
deflection and vibration. While
shaft sleeves may simplify maintenance, solid shafts reduce it.
The formula I = L3/D4 offers an
index of deflection to compare
pump designs where:
I = index of deflection
L = length of shaft overhang
from bearing
D = rigid shaft diameter
Proper selection of wet-end
materials of construction and
mechanical seal design offset
positive features of the shaft
sleeve option.
Note: The Deflection Index provides an approximate comparison
of shaft stiffness. A detailed
analysis should be made to
determine actual shaft deflection.
Select the impeller setting.
Each notch on the carrier ring
represents exactly 0.10 mm
(0.004 in) of clearance. For an
impeller setting of 0.5 mm
(0.020 in) count five notches
counterclockwise.
Move the bearing carrier
clockwise the selected
number of notches. Tighten
the setscrews and check the
impeller clearance with the
feeler gauge.

Advanced Mark 3 SealSentry
Design Technology
SealSentry chambers maximize
seal life, reduce pump operating costs and improve pump
reliability.
• Extend seal life
– Self-flushing
– Self-venting
– Self-draining
• Reduce maintenance and
repair costs
• Permit use of less expensive
seals and flush plans
– Flush plans 11, 32, 52, 53,
etc. can be eliminated
• Increase mechanical seal life
• Provide a safer environment
for personnel
Flow Modifiers (FM) Extend
Mechanical Seal MTBPM
• Flow modifiers redirect flow
from circumferential to axial
• Balanced flow with low
pressure drop in the chamber
helps keep solids in suspension, minimizing erosion
• The mechanical seal creates a
centrifuging action away from
its parts
• Solids and slurry merge
into the returning flow path
and are flushed out of the
seal chamber

Impellers
Flowserve Durco reverse vane
impellers deliver unequalled
efficiency and performance.
This exclusive impeller design
extends bearing and seal life.
• Low, Predictable Seal
Chamber Pressure and Thrust
Loads resulting from back
vane pumping action and
balance holes
• Lowest Required NPSH of any
standard pump
• Rear Cover Plate Wear
Surface as the flow path
exits the rear of the impeller.
Abrasive wear is on the rear
cover rather than the more
expensive casing
• In-shop Impeller Adjustment
with the only impeller design
that takes full advantage of
the back pull-out feature.
Since the critical running
clearance is set between the
rear of the impeller and the
rear cover plate, both impeller
and mechanical seal settings
can be done in the shop, “on
the bench,” instead of under
adverse field conditions
• Repeatable Performance
Assurance with the only
impeller design that offers
repeatable seal chamber
pressures and bearing
thrust loads
Exclusive Reverse Vane
Impeller with balance
holes offers important
performance enhancing,
maintenance-reducing
advantages.
Front Vane Open Style
Impeller is fully interchangeable with the
reverse vane impeller.
Excellent choice for
fibrous, stringy materials
and certain applications
requiring high shear
against the casing.
Recessed Impeller
pumps offer excellent
solids-handling
capabilities.

A
Baseplates are Fundamental
to Extending Pump Life
The test stand provided three
corner support of the ungrouted
baseplates. The addition of
weights on the unsupported
fourth corner caused baseplate
distortion. This distortion
resulted in measurable shaft
movement that can cause
problems with field installations and negatively affect
pump reliability and life.
The twist test is a means
of comparing rigid baseplate
designs. Correctly installed
rigid baseplates should not
experience these twist effects.

the results of baseplate testing

Pump Safety
Accessories
ClearGuard and DurcoShield
Non-metallic Safety Guards
ClearGuard and DurcoShield
pump guards permit visual
inspection of coupling and seal
areas, respectively, while
protecting personnel from
potential safety hazards of
rotating parts. Constructed of
tough, durable, and transparent
polycarbonate with UV light
inhibitors, they are designed
to withstand tough chemical
processing environments.
DurcoShield* Splash and Shaft
Guard is a one-piece shield that
envelops the open areas between
the bearing housing and casing.
Suitable for applications to
150°C (300°F), DurcoShield
protects users from:
• Process fluid spray
• Rotating shaft and seal
components
ClearGuard Non-metallic
Coupling Guard meets
machinery guard safety
guideline. Nothing larger than
6 mm (0.24 in) in diameter
can enter the shell. Furthermore,
the ability to inspect the
coupling through ClearGuard
can provide early warning of
deteriorating or malfunctioning
components.
Note: DurcoShield is not a
containment system or a seal
backup system. It is a limited
protection device. It will
reduce, but not eliminate,
the probability of injury.

Sealmatic
Pump
Dynamic Sealing
With the Flowserve Mark 3
Sealmatic pump, no mechanical
seal is needed during operation.
A dynamically sealing repeller
(expeller) expels fluid from the
seal chamber, making it ideal for
hard to seal applications.
Furthermore, the need for external
flushing and process contamination control are eliminated.
Applications
• Tough services where sealing
is difficult
• Services where a flush
is undesirable
(e.g., evaporator feed)
• Continuous, around-the-clock
applications
• Batch operations where a “run
dry” condition might exist
(7400 gpm)
• Heads to 230 m

The Priming Cycle
The Mark 3 Unitized SelfPriming pump uses liquid
recirculation to prime the pump.
The pressure differential
between the aerated liquid
at the impeller and the nonaerated liquid in the priming
chamber creates a vacuum that
pulls liquid up the pipe. As a
result, the Mark 3 Unitized
Self-Priming pump is ideal
for suction lift applications or
pumping liquids with entrained
air or gases.

impeller shall maintain low seal chamber pressures, which shall
be published on the pump performance curve, and shall be
repeatable after maintenance. The impeller clearance shall be set
externally. The impeller-to-shaft connection shall be a metal-tometal fit. A silicon O-ring encapsulated in PTFE shall be used to
protect the impeller threads. Impeller shall be balanced to ISO
1940 Grade 6.3 criteria.
Shaft: Shall be of solid construction to maximize strength and
rigidity. The shaft shall consist of a steel power end friction welded
to an alloy wet end. Shaft deflection shall not exceed 0.05 mm
(0.002 in). The shaft key slot shall be designed with a machined
radius “sled runner” edge to provide maximum strength at the
coupling. Critical surfaces shall be ground to 0.005 mm (±0.0002
in), maximum roughness at the seal chamber shall be 0.40 µm
(16 µin).
Rear Cover: Shall be suitable for accepting various seal designs
from all major seal manufacturers. Cylindrical bore standard,
cylindrical bore oversize, and tapered options shall be available.
Tapered options shall include eight evenly spaced, tapered and
sloped flow modifying devices integrally cast into the seal
chamber. The flow modifiers shall facilitate movement of solids,
vapors, and heat away from the mechanical seal. The tapered
seal chambers shall be designed to be self-flushing. For optimum
performance the seal and gland shall be selected to locate the
seal faces directly in the flush path. Integrally cast jackets shall
be available.
6-1
Mark 3
Bearings: Shall be large, heavy-duty, ball bearings. The inboard
bearing shall be a single row, deep groove. The outboard shall be
double row angular contact, deep groove. An optional duplex
angular contact outboard bearing shall be available for high thrust
load applications. Both bearings shall be located by a shoulder on
the shaft. The inboard bearing shall float in the bearing housing,
while the outboard bearing shall be locked in place in the bearing
carrier. The bearings shall exceed B10 life of 17 500 hours and
allow less than 0.025 mm (0.001 in) end play.
Bearing Housing: Shall be sealed to prevent contamination of
the lubricant. The oil fill hole at the top of the housing shall be
plugged. No vented constant level oiler shall be used. The housing
shall be sealed with Inpro VBXX bearing isolators. A magnetic
drain plug shall be used. A large easy to read one inch NPT sight
glass shall be used. The impeller clearance shall be set by the
micrometer adjustment method. This method shall cause the shaft
and impeller to move axially. Indicators shall be cast into the
bearing carrier which represent 0.102 mm (0.004 in) of axial
impeller travel. This allows accurate impeller clearance to be
established externally without the use of measurement devices.
The bearing carrier threads shall be protected by two O-rings.
Coupling Guard: Shall conform to ASME B15.1 and shall be of the
“clamshell” design. It shall extend from the motor to the bearing
housing, but shall not be attached to either. The guard shall be
bolted to the baseplate.

Mark 3 Competitive Analysis
COMPETITIVE ANALYSIS
The Mark 3 offers three distinct features not available with any
other ANSI pump line. These features offer specific, measurable
benefits for the end-user. These features are the power end design
and options, the reverse vane impeller, and the SealSentry™
seal chambers. These features were presented and discussed,
in detail, in Section 1.
The major competitor of the Mark 3 is the Goulds 3196 ANSI
pump line. Below are some of the weaknesses of the Goulds
design:
• Only available with an open impeller
• Does not offer a seal chamber with performance equal to the
Mark 3 FM design. The Goulds Taperbore Plus VPE design is
limited to 10% solids and is not available in ductile iron. In
addition, at low flows the VPE can result in negative seal chamber
pressures.
• Mark 3 Group 2 and 3 shafts are larger in diameter and provide
more robust deflection resistance which results in longer
mechanical seal life. In addition, the Mark 3 Group 2 power end
uses one size larger bearings which gives substantially longer
bearing life.
• The Goulds jackscrew impeller adjustment design is slower and
less accurate than the micrometer adjustment of the Mark 3. In
addition, the jackscrew design can lead to uneven bearing loading
and reduced bearing life.
Below are some of the negative comments offered by Goulds about
the Mark 3 pumps and appropriate counter responses to these
comments:
• “The reverse vane impeller will clog.” There are a few services
where this might be of concern such as stringy, fibrous solids.
We can offer an open impeller for those very few occasions
where this might be an issue. When given a choice, though,
8-1
Mark 3
customer overwhelmingly select the reverse vane design because
of the measurable benefits provided.
• “The reverse vane impeller cannot pass solids like an open
impeller.” The maximum sphere that will pass through the Mark 3
reverse vane and open impellers is shown on the published
performance curves (see Section 10). Since we offer both design,
we can compare and the data show that the sphere size is
generally equal for the same size pump with either the reverse
vane or open impeller. This makes sense in that the open impeller
is set very close to the casing and the casing essentially forms a
front shroud.
• “The threads on the bearing carrier of the power end will corrode
and it will not be possible to set the impeller clearance.” The
threads are protected, both inboard and outboard, with o-rings.
Corrosion of the threads has not been a problem.
• “The flow modifiers (FM) in the SealSentry are only suitable for
low solids concentrations.” We have documented performance
data for the FM design in services with up to 60% solids where a
single mechanical seal with no seal flush system performed with
no damage to the seal.
• “The larger oil sump provided with all sizes of the 3196 provides
extended bearing life.” There are two major factors that determine
bearing life; bearing temperature and purity of the lubricant.
Extensive testing has shown that the Mark 3 bearing
temperatures are well within bearing manufacturers’
recommended temperature ranges and the standard Mark 3
power end provides the protection required to prevent lubricant
contamination. The upgraded ANSI 3A design comes with a 3year bearing warranty thus indicating our confidence in the
environment provided for the bearings.
These are the major negative points made by Goulds. The Mark 3
has been in use long enough to have established a reputation for
long, reliable performance in the most difficult services. We should
not be afraid to compare the performance of the Mark 3 against
the 3196 in any application.

Mark 3 Performance Curves
PERFORMANCE CURVES
The Mark 3 product line is fully supported in PROS and
performance curves can be generated and printed there; however,
the published performance curves are reproduced here because
they show additional information:
• Impeller eye area
• Maximum sphere that will pass through the impeller
• Curve number
• Stuffing box (seal chamber) pressure curves. These curves are
unique for the Mark 3 as no other ANSI pump manufacturer
published such curves. With these curves, it is possible to
estimate the precise conditions in the seal chamber and predict
mechanical seal performance.

Mark 3 Miscellaneous Information
MISCELLANEOUS INFORMATION
Frequently Asked Questions (FAQ’s)
Standards
1. What are the viscosity limits for Mark 3 pumps?
Viscosity is a measure of the resistance of a liquid to flow.
As viscosity increases, more energy is required to pump the
liquid. PROS performs viscosity corrections when selecting
Mark 3 pumps; however there are limits as to the maximum
viscosity liquid each size pump can handle. These limits are:
A list of Flowserve Global Standards pertinent to the Mark 3 line
are shown below. For copies of these standards, contact the
Mark 3 Pump Design Center (see table in Section 5 showing
relevant personnel).
• J1-0020-016 DuPont Joint Product Specification for ANSI Pump
• J1-1000-013 Impeller Balance Limits
• J1-1000-023 Required Tagging and I.O.M. Manual for ANSI and
ISO Chemical Pumps
• J1-1000-027 ANSI Baseplate Tolerances
• J1-1000-034 Shaft Alignment Procedure Using a Dial Indicator
or Laser Alignment System
• J1-1000-038 Paint for Standard and Special Finish Coat
• J1-1000-041 Long Term Storage Recommendations for
• J1-1100-003 Mark II and Mark III Production and Test Standard
• J1-1100-012 Sound Measurement for ANSI B73 Centrifugal
Pumps
• J1-1160-004 ANSI and ISO Polybase Baseplates
Quickship Program
Chesapeake has a program in place to ship Mark 3 pumps of
certain standard configurations and materials in 48 hours. The
application engineer that supports the local sales efforts for Mark 3
pumps has access to the specifics of this program. All Quickship
inquiries should be coordinated through the local application
engineer.
Retrofit/Upgrade – Mark 2 to Mark 3
The Mark 3 design offers many enhancements over the Mark 2;
however, the Group 2 & 3 hydraulics are, in most cases, identical.
It is possible to upgrade Mark 2, Group 2 & 3, pumps to the
Mark 3 by simply changing the power ends. Upgrading the
Mark 2, Group 1, pumps is a bigger challenge. The Mark 3,
Group 1, pumps have a larger diameter shaft plus only one size
rear cover / seal chamber is used. The recently introduced Prima3
power end design allows this upgrade to be performed. The new
power end does require a new rear cover / seal chamber to match
the larger shaft. However, using the Prima3 permits the end-user
to enjoy all the benefits of the Mark 3 power end design while
maintaining the system hydraulics.
• Group 1 – 500 centipoise
• Group 2 – 1,000 centipoise
• Group 3 – 2,000 centipoise
2. What are the standard materials of construction for the
Mark 3?
There is a table in Section 1 that lists the standard materials
of construction for the Mark 3. Published pricing is posted for
these materials plus standard lead times have been established.
However, the Mark 3 can be produced in other alloys on request.
Requests should be coordinated through the application engineer
that supports the local sales efforts.
3. Who are the major competitors for the Mark 3?
There are a number of manufacturers of ANSI pumps but there is
only one major competitor and that is ITT-Goulds. Others offering
ANSI pumps include Sulzer/Ahlstrom, Peerless/Labour, Dean
Brothers, and Blackmer/Chesterton. In addition, there are a few
replicators offering ANSI-dimensioned pumps some of which are
copies of the Mark 3.
4. Is the Mark 3 fully ANSI compliant?
The Mark 3 is fully compliant with ASME (ANSI) B73.1-2001.
5. Is the Mark 3 compliant with any provisions of API 610?
No, there is no compliance of the Mark 3 with API 610.
6. Is the Mark 3 compliant with API 682?
API 682 is essentially a mechanical seal specification and the Mark
3 can be fitted with an API 682, Category 1 mechanical seal.
7. Is the Mark 3 compliant with PIP (Process Industry Practices)
Standard RES P73H-97?
After some initial acceptance shortly after its introduction, this
standard is not often invoked. There are provisions that require
some pump modifications for compliance plus there are some
provisions that should be challenged. If this standard is invoked,
contact should be made with the Mark 3 Pump Design Center
(see table in Section 5 showing relevant personnel).
There are two other relative PIP issues. The pump data sheet from
Standard RES P73H-97 has been adopted by ASME B73.1-2001.
Also, there is a PIP Standard RESP002 regarding ANSI pump
baseplates and the Type E baseplate complies with this standard.

8. What determines the minimum recommended flow for the
Mark 3?
There are two relevant minimum flow values: minimum continuous
flow (MCF) and minimum thermal flow (MTF).
MCF is shown by pumps size in ASME B73.1-2001, Table 5, and
is presented as a percentage of best efficiency point (BEP). The
parameters that influence MCF levels are vibration, shaft deflection,
and bearing life. B73.1 states that pumps can be reliably operated
below the levels shown in Table 5 so long as the requirements for
vibration, shaft deflection, and bearing life are met. The published
MCF values for the Mark 3 (see Section 4 for reference to the
Mark 3 values) differ some from those published in B73.1 because
the critical parameter requirements are met. It should be noted that
MCF relates to continuous flow. A pump should not be selected
that would operate continuously below this minimum. Infrequent
and short-duration operation below the minimum value can be
tolerated without measurably impacting pump reliability.
Some of the input energy to a pump is transformed by fluid friction
to heat. As pump operation moves toward zero flow, more of the
energy is imparted to the fluid. Some level of minimum flow is
required to avoid damaging the pump. This is called MTF and this
flow is determined by the temperature rise above which the fluid
being pumped is adversely affected (most notably boiling) or the
temperature level achieved adversely affects components of the
pump. The minimum flow rate required to remain below a specified
temperature rise can be calculated (see equation below). For most
standard Mark 3 pumps, MCF is significantly higher than MTF.
However, the Lo-Flo design has no MCF value so MTF becomes
the controlling minimum flow and must be considered.
Q = (5 X BHPo X Chp) / (∆T X sp ht)
Q = minimum flow rate, in gpm
BHPo = non-viscous performance curve HP at shutoff
sp ht = specific heat of liquid
11. What are the solids handling capabilities of Mark 3 pumps?
This is a very broad question involving many factors such as the
size and shape of the solids, the hardness of the solids and the
concentration of the solids. Each of these factors is discussed
briefly as follows.
The performance curves in Section 10 show the maximum sphere
diameter that will pass through the impeller thus defining the
largest solid each pump size can handle. It should be noted that
the reverse vane impeller design will pass essentially the same size
sphere as the open impeller. If the solids are fibrous and stringy,
then the open impeller should be selected.
Hardness of the solids is a critical factor since hard particles can
cause significant abrasive damage. To minimize damage from hard
particles, pump selection is key. The pump should be sized to
operate at, or very near, the best efficiency point (BEP). Also, the
pumps should be selected to run at as low a speed as possible.
Please note that certain sizes of the Mark 3 line are available in
high chrome iron, an extremely hard, abrasion resistant material.
Mark 3 pumps can handle fairly high solids concentrations.
Services containing up to 60% solids have been pumped.
Services containing significant levels of solids, particularly abrasive
solids, present serious challenges. Discussions with pertinent
individuals at the Mark 3 Pump Design Center (see table in
Section 5) are recommended.
12. Are special tools required to maintain Mark 3 pumps?
Standard hand tools are normally adequate for performing routine
maintenance on the Mark 3. To assist in maintaining these pumps,
it is recommended that the Flowserve Mark 3 Tool Kit be used.
This tool kit contains an impeller wrench that greatly simplifies
installation and removal of the impeller. Also, a set of nose cones
are included which protect shaft threads and o-rings during
maintenance.
∆T = maximum allowable temperature rise, °F
Chp = viscous HP correction factor
9. Over what temperature range can the Mark 3 operate?
The Mark 3 can operate in the range of -130°C (-200°F) to 370°C
(700°F); however, when operating below -29°C (-20°F) or above
149°C (300°F) certain modifications are required and other
modifications are recommended. See Section 4 for reference to a
list of these modifications.
10. Is there a standard corrosion allowance for the Mark 3?
The corrosion allowance is at least 3.2 mm (0.12 in). This
allowance applies to the casing, the rear cover/seal chamber,
and the gland.
13. Are all Mark 3 casing single volute?
No, some of the larger casings have dual volutes due to the high
radial loads generated. The pump sizes that utilize dual volutes are:
2K6X4-10, 3K10X8-14, 3K8X6-16A, 3K10X8-16, and 3K10X8-16H.
14. What are the impeller balancing criteria for Mark 3 pumps?
B73.1 allows single plane (static) balancing; however, most Mark 3
impellers receive a single plane dynamic balance while a few
receive a two plane dynamic balance. Those sizes satisfying the
following parameter are single plane balanced:
(Maximum Outside Diameter) / (Total Width at Periphery) ≥ 6
There are three sizes of Mark 3 impellers that fall outside this
parameter and these are two plane balanced. These three sizes are:
2K6X4-10H, 3K10X8-14, and 3K10X8-16H.
All balancing is performed to ISO DR 1940 Grade 6.3 tolerance
criteria. Other tolerance levels can be provided.

15. How are Mark 3 impellers affixed to the shaft?
All Mark 3 impellers are threaded to the shaft. Rotating the pump
backwards can cause the impeller to spin forward (off) the shaft
and usually causes damage to the impeller and casing. Some size
pump can be fitted with a special fastener through the eye of the
impeller into the shaft to avoid spinning the impeller off the shaft
during reverse rotation. This modification should only be offered in
extreme circumstances. Contact Mark 3 Pump Design Center
personnel before offering this option. Impellers for the 2K6X4-10,
3K10X8-16, and 3K10X8-16H have threaded inserts that attached
the impeller to the shaft. These inserts are used to provide added
strength in the threaded area. The inserts are put into the impeller
before final machining and they cannot be replaced if ever
removed.
16. What is the standard flange configuration for the Mark 3 and
what options are available?
The standard configuration is Class150 flat-faced flanges. The
standard finish of the flanges is in accordance with ASME B16.5.
Raised face configurations are available as are Class 300 ratings.
Also, special finishes and drillings can be provided. See Section 4
for further reference to details regarding Casing Options.
17. What is a 1J pump?
Mark 2, Group 1 pumps had a 1-1/8" diameter shaft through the
seal chamber area. The Mark 3, Group 1 pump has a 1-3/8"
diameter shaft in this region. A 1J power end provides all the Mark
3A power end features but with a 1-1/8" diameter shaft. This power
end was developed so that existing Mark 2 hydraulics could be
maintained, but with the Mark 3A power end advantages. In
addition to standard Mark 2, Group 1 pumps, the 1J power end is
used with Group 1 Unitized Self-Priming and Recessed Impeller
designs.
Composite designs are comprised of a carbon steel shaft with a
permanently attached (not replaceable) sleeve. This design permits
utilizing a specialty material in the seal chamber area of the pump
economically. There are three options available: carbon steel/high
silicon iron (BB77), carbon steel/cobalt alloy (BBC8) and carbon
steel/ceramic (BBC3).
Finally, shafts with replaceable sleeves can be provided. The shaft
can be made from one material or friction welded. The sleeve can
be almost any castable and/or machineable material. This design is
typically used in high alloy pumps where corrosion resistance is of
paramount importance.
19. When should duplex angular contact bearings be used?
Many customers specify these bearings because they feel the
increase in reliability is worth the small price adder. Also, these
bearings are required with the 13" Lo-Flo pump under certain
operating conditions. To see if these bearings should be specified
for other applications, the Suction Pressure Rating curves for the
standard Mark 3 pumps should be consulted (See Section 4 for the
location of these curves).
20. When should greased bearings be used?
This is usually a customer preference issue. Greased bearings can
present less hassle and mess than oil bath bearings plus some
consider them more foolproof. Greased bearings can be either
regreasable or greased-for-life (double shielded). Flowserve does
not recommend sealed bearings because of the frictional heat
generated by the lip seals.
21. How is specific speed (NS) calculated?
The formula for calculating specific speed is:
1/2
18. What factors determine the shaft design that should be used
with the Mark 3?
There are four shaft designs available with the Mark 3: solid,
friction welded, composite, and sleeved. Both the solid and friction
welded designs offer the same level of rigidity. These designs are
recommended by Flowserve rather than sleeved shafts because
they reduce the harmful effects of deflection and vibration thus
improving pump reliability. Below is a brief discussion of each
design.
Solid shafts, as the name implies, are comprised of the same
material end-to-end plus no sleeve is used. Theoretically, a solid
shaft can be made from any machineable material; however, cost
and mechanical properties must be considered. Solid shafts are
available as standard in carbon steel and 316 SS, and are the
standard offerings in ductile iron and 316 SS (CF8M) pumps
respectively.
Friction welded shafts are constructed from two separate materials,
normally a lower cost, stronger material on the coupling end and a
more corrosion resistant alloy on the impeller end. Standard
configurations are carbon steel/316 SS (ZH), carbon steel/Alloy 20
(ZC20), 304 SS/Hastelloy B (EHB) and 304 SS/Hastelloy C (EHC).
The ZC20 shaft is the standard offering for CD4M and D20 (Alloy
20) pumps.

NS = NQ / H
3/4
NS = specific speed in U.S. units
N = rotative speed, in revolutions per minute
Q = capacity, at best efficiency point, in gallons per minute
H = total head, at best efficiency point, in feet
Specific speed is a dimensionless index number that relates the
hydraulic performance of a pump to the shape and physical
proportions of its impeller.
22. How is suction specific speed (NSS) calculated?
The formula for calculating suction specific speed is:
NSS = NQ1/2 / hsv3/4
NSS = suction specific speed in U.S. units
N
= rotative speed, in revolutions per minute
Q
= capacity, at best efficiency point, in gallons per minute
hsv = net positive suction head required (NPSHr), at best
efficiency point, in feet
Suction specific speed is a dimensionless rating number that
relates the ability of a pump to operate under conditions of low
available net positive suction head. PROS displays suction specific
speed for Mark 3 pumps.

23. What is NPSH?
NPSH is net positive suction head. There are two critical NPSH
values, available NPSH and required NPSH. Available NPSH is an
indication of the proximity of the liquid being pumped to its vapor
pressure. Required NPSH is indicative of the reduction in total
head as the liquid being pumped enters the pump. Required NPSH
is a characteristic of each pump size and is determined by testing.
Available NPSH is a calculated value and is a characteristic of the
piping system. Available NPSH can be calculated as follows:
hsv = hpsa + hss – hfs - hvpa
hsv = available net positive suction head in feet of liquid
hpsa = suction surface pressure, in feet of liquid, absolute,
on the surface of the liquid from which the pump
takes its suction
hss = static suction head, in feet of liquid.
hfs
= friction head loss, in feet of liquid, between the liquid
surface in the suction tank and the suction flange of
the pump
hvpa = vapor pressure of the liquid, at the pumping
temperature, in feet of liquid, absolute
Available NPSH must exceed required NPSH to avoid vaporization
of the liquid in the pump. This vaporization is called cavitation.
For dependable pump operation, the available NPSH should be
20% or 1.5 m (5 ft) over the required NPSH, whichever is greater.
24. What is cavitation?
Cavitation is name given to the vaporization of the pumped liquid
in the pump. Cavitation is normally accompanied by noisy
operation. The noise is frequently characterized as corn popping.
Cavitation is a serious issue which can reduce performance and
cause serious damage to the pump.
25. What are the torque characteristics of Mark 3 pumps?
Figure 11.1 is a typical torque-speed curve for Mark 3 pumps.
From this curve, it can be surmised that, in general, the starting
torque for any Mark 3 pump is approximately 10% of the full load
torque. One of the inherent advantages of pumps like the Mark 3 is
that the low starting torque requirements and the low inertia make
them easy to start. Full load torque for the Mark 3 can be
calculated as follows:
Full Load Torque (lb-ft) = 5252 X (Full Speed HP / Full Speed RPM)
Starting torque is influenced by pump size, mechanical seal type,
and other factors. If an accurate starting torque value is required,
contact the Mark 3 Pump Design Center.
26. What is critical speed?
Another pump characteristic that is sometimes requested is the
critical speed. The critical speed is the natural frequency of lateral
vibration of the shaft/impeller assembly. If a pump is operated at
its critical speed, any rotating imbalance would be in resonance
with the natural frequency and the resulting vibration would be
many times greater than that occurring at other speeds. Most
pump specifications state that a pump should not operate
continuously between 80-120% of the critical speed. The critical
speeds for Mark 3 pumps are also shown in Table 11.1. The
maximum operating speeds for all Mark 3 pumps are well below
80% of the critical speed.
27. What is the correct direction of rotation of Mark 3 pumps?
All Mark 3 pumps turn clockwise when viewed from the motor end.
It is absolutely essential that correct motor rotation be assured
before starting the pump. Incorrect motor rotation for even a very
short time interval can cause the impeller to unscrew from the
shaft and result in significant damage to the impeller, casing, shaft,
and mechanical seal.
Another event that can cause incorrect rotation is reverse flow of
liquid through the pump. This might occur when a pump is shut
off and a high column of liquid is present in the discharge piping.
This will not cause the impeller to unscrew from the shaft since the
torque that produces the reverse rotation is applied to the impeller.
A counterclockwise torque, viewed from the motor end, applied to
the impeller will tend to tighten the impeller to the shaft.
Conversely, if liquid is forced into the pump in the normal direction
(from the suction to the discharge), the pump rotation will be in
the correct direction, but the torque applied to the impeller will
tend to unscrew it. This situation should be avoided.
28. What are the applicable performance test standards for the
Mark 3?
If a performance test is required, B73.1 specifies testing in
accordance with HI (Hydraulics Institute) Standard 1.6. There are
two test levels in HI 1.6; A or B. The significant differences
between the two involves the permissible range of the head around
the specified duty point. Level B allows a minor negative tolerance
on the specified head value while Level A does not. Level B should
be the default test standard in PROS when sizing and selecting
Mark 3 pumps. Level A should be selected only when required by
the customer. Selecting Level A will result in horsepower and
efficiency penalties versus Level B which can be detrimental in a
competitive bid situation.
Other test standards can be invoked such as API 610 and ISO
3555. API 610 test standards are similar to HI 1.6 but should be
carefully defined before accepting as part of an order. ISO 3555
involves a quite different set of procedures. ISO 3555 acceptance
requirements can be met but exception should be taken to the
actual procedures.
Sometimes an engineering contractor or end-user may want to
calculate various torque limits. In addition to the torque-speed
curve, the WR2 (mass moment of inertia) value for each pump
size is needed. These values are shown in Table 11.1.

29. What is curve “droop”, are Mark 3 pumps subject to this
phenomenon, and can it be avoided?
Curve “droop” is the term used to describe the slight fall off in
head near shut-off that can be detected during performance
testing. “Droop” is related, in part, to the nature of the test
systems used and, in part, to the design characteristics of ANSI
pumps. Designing out “droop” is possible but would result in
some sacrifices in performance. Normally, the “droop” exhibited is
not an issue because it occurs below recommended minimum
continuous flow. Mark 3 pumps, in fact all ANSI pumps, are
subject to this phenomenon. It can be avoided usually by providing
an orifice plate on the discharge of the pump. The issue of “droop”
can be important if a customer’s specification requires a
continuously rising head curve and/or a guaranteed shut-off head
value. When quoting to such a specification, assistance should be
sought from the Mark 3 Pump Design Center to insure that the
correct pump is selected and any required modifications (e.g.,
orifice plate) are included.
30. Can noise level certification be provided for the Mark 3?
Specific testing for an order cannot be performed. Typical sound
pressure levels by motor size and speed are referenced in Section
4. For specific sound levels by pump size based on previous test
data, consult with the Mark 3 Pump Design Center.
31. What are the hydrostatic test requirements for the Mark 3?
Per B73.1, all casings, rear covers/seal chambers, and jackets are
hydrostatically test at 1.5 times the maximum design pressure at
38°C (100°F) for 10 minutes. This test can be certified. Other
testing can be provided (e.g., 30 minute test).
32. What baseplate options are available with the Mark 3?
Five pre-engineered baseplate designs are available (see Section 4
for reference to more detailed discussion):
Type A – This is the lowest cost design. It is a formed steel
configuration with carbon steel being the standard material but
11-5
Mark 3
other materials (e.g., 316 SS) are available. The Type A offers good
flatness and rigidity. It is normally foundation mounted but limited
stress stilt mounting can be accommodated. It complies with
B73.1 dimensions.
Type B – This is a vinyl ester bonded polymer concrete design and
offers many benefits at a modest cost adder over the Type A. This
design is very rigid, has excellent vibration dampening properties,
and is very corrosion resistance. It can be either foundation or stilt
mounted and meets B73.1 dimensions.
Type C – This is a formed metal design with reinforcement
enhancements for increased rigidity; in fact, this is the most rigid
standard design. This design can only be stilt mounted. The
standard material of construction is carbon steel but stainless steel
is available. It also meets B73.1 dimensions.
Type D – This is a reinforced design that offers better rigidity than
the Type A. It can only be foundation mounted. Carbon steel is the
standard material with stainless steel available. It also meets
B73.1 dimensions.
Type E – This is a reinforced design with machined mounting
pads thus offering excellent rigidity and flatness. It can only be
foundation mounted. Carbon steel is the standard material with
stainless steel available. This design meets B73.1 dimension
requirements and complies with the PIP RESP 002 standard.
33. What are the pump volumes for the Mark 3?
This information is frequently requested so the temperature rise in
the pump when running against a closed discharge valve can be
estimated. Table 11.2 shows the volumes for the standard pumps
(this is the volume of liquid that an assembled pump with full
impeller would hold with blanked flanges) and Table 11.3 shows
the unitized self priming design (priming volume only and total
volume).

arising out of, connected with, or resulting from the performance or breach of the contract of purchase shall in no event exceed the amount of the price of the specific
Equipment or Service which gives rise to the claim. In applying the monetary limitation of Seller's total liability, such liability shall be reduced by the sum of (1) any
damages paid to Purchaser by Seller, (2) any costs incurred and settlements made by Seller under Section 4 "Warranties" and (3) any refund of the price for the
Equipment or Services in the event of a rescission.
In all cases where Purchaser's claim, whether based upon contract, tort (including negligence), strict liability or otherwise, involves defective work or nonconforming
Equipment or Services, or damage resulting therefrom, Purchaser's exclusive remedies and Seller's sole liability shall be those specifically provided for under Section 4
“Warranties."
Seller shall not be responsible for the acts, omissions or workmanship of the employees, contractors, subcontractors, agents of Purchaser, or of third parties.

Purchaser's employees, contractors, subcontractors, agents, materialmen, or of third parties, (b) failure to observe Seller’s advice, (c) failure or malfunctioning of any tools,
equipment, facilities or devices not furnished by Seller, or (d) use of instruments or the making of adjustments by Purchaser's employees, contractors, subcontractors or
agents.

contract of purchase, shall Seller be liable to Purchaser for losses or damages caused by reason of loss of use, revenue or profits, or cost of capital, or special, indirect,
incidental, consequential or penal damages of any nature, and Purchaser shall indemnify Seller against any such claims by any third party.
The liability, if any, for any claims, whether based upon contract, tort (including negligence), strict liability or otherwise, for any loss or damage arising out of, connected
with, or resulting from, the performance or breach of the contract of purchase shall be limited to specifically identified written claims submitted to Seller prior to the
expiration of the applicable warranty period as set forth under Section 4 "Warranties."
The provisions of this Section "General Limitations of Liability" shall also protect Seller's Suppliers, shall apply to the full extent permitted by law regardless of fault and
shall survive termination, cancellation or completion of the work under the contract of purchase.
9. Severability:
If any provision of the contract of purchase is deemed to be void, invalid or inoperative for any reason, or any phrase or clause within such provision is deemed to be void,
invalid or inoperative, that phrase, clause or provision shall be deemed modified to the extent necessary to make it valid and operative; or if it cannot be so modified, then
such phrase, clause or provision shall be deemed severed from the contract of purchase, with the remaining phrases, clauses and provisions continuing in full force and
effect as if the contract of purchase had been signed with the void, invalid or inoperative portion so modified or eliminated.
10.Cancellation:
Purchaser may cancel the contract of purchase only upon written notice and upon payment to Seller of reasonable and proper cancellation charges.
If in the opinion of Seller the financial condition of Purchaser does not justify continuance of the contract, Seller may require full or partial payment in advance or shall
receive reimbursement for its reasonable and proper cancellation charges. In the event of bankruptcy or insolvency of Purchaser or in the event any proceeding is brought
against Purchaser, voluntarily or involuntarily, under the bankruptcy or any insolvency laws, Seller shall be entitled to cancel the contract of purchase at any time during
the period allowed for filing claims against the estate and shall receive reimbursement for its reasonable and proper cancellation charges.
11.Suspension:
In the event Purchaser elects to suspend work under the contract of purchase, Purchaser shall notify Seller at least one week in advance of the suspension date. This
notification shall be in writing and include the anticipated suspension period. Upon receipt of Purchaser’s written notice of removal of such suspension, Seller shall advise
Purchaser of the price adjustment which shall be based on Seller's ability to reallocate manpower, material and equipment during the suspension period and any other
differences in costs caused by the suspension, with such price adjustment to be reimbursed by Purchaser.
12.Assignments:
Any transfer or assignment (including any transfer or assignment by operation of law or otherwise) of the contract of purchase or any rights thereunder by Purchaser

Mark 3 Special Configurations of the Pump
SPECIAL CONFIGURATIONS OF THE PUMP
There are four special configurations of the Mark 3 pump: Lo-Flo,
Sealmatic, Unitized Self-Primer and Recessed Impeller. These
special configurations use many standard components, reducing
parts inventory requirements. A brief description is included below
with links to more detailed information.
Mark 3 Lo-Flo
Standard centrifugal pumps are designed to operate at, or near,
a best efficiency point (BEP). In this range of operation, bearing
loads and vibration are minimized. However, there are many
applications requiring low-flow, high-head performance. The
Mark 3 Lo-Flo is designed to fill this need. This pump uses
only a special impeller and casing, all other parts are standard
Mark 3 components. Sources of information on this pump can be
found at:
Unitized Self-Primer
This pump can draw liquid from sources below the centerline of
the discharge making it ideal for pumping from sumps and tank
cars. The only non-standard part for this pump is the casing.
All other parts are standard Mark 3 components. Sources of
information on this pump can be found at:
Section 2 – Product Brochure (Literature No. PS-10-13), pages
26-27, contains major features and benefits of the Mark 3 Unitized
Self-Primer.
Section 4 – General Engineering Data has references and links to
Technical Bulletin (Literature No. P-10-501) regarding the Unitized
Self-Primer design.

making it suited for handling solids efficiently. The only nonstandard components include the casing and impeller. All other
parts are standard. Sources of information on this pump can be
found at:
Section 12 – Pricing for Pumps, Modifications, Accessories, and
Parts has links to the relative price pages for the Lo-Flo.
Sealmatic
With the Sealmatic design, no mechanical seal is required making
it ideal for hard to seal applications. This pump uses special covers
and includes a repeller. All other parts of the pump are standard
Mark 3 components. Sources of information on this pump can be
found at:
