CENTRIFUGAL PUMP PARTS
CENTRIFUGAL PUMP SHAFT
WEAR PLATE REPLACEMENT
Since the impeller end of the shaft is exposed to the fluid in
the 1-7/8 in. pump, Baker SPD has chosen a Stainless
Steel shaft to prevent corrosion. The shaft is
designed to transmit the required horsepower
for maximum output in the most severe
applications. Other specialized shaft
designs are available upon
request.
Baker SPD has incorporated the wear plate
into its new Stuffing Box Cover design.
However, for preexisting pumps in the field
which have a
removable wear
plate, Baker
SPD still offers
a separate
wear plate as a
repair part, thus
giving our valued
customers the option to choose
between the new “all in one” design or
continuing with their existing configuration.
CENTRIFUGAL PUMP IMPELLER
A semi-open design has been selected for all sizes from the
2 x 3R x 13 in. to the 6 x 8R x 13 in. The semi-open vane design provides efficient fluid intake and discharge through the
power side of the Impeller. The Impeller is designed with back vanes, which reduces wear on the Stuffing Box
face. The back vanes also reduce the wear by limiting the inflow of solids to the Stuffing
Box, thus enhancing the life of
the sealing mechanism.
CENTRIFUGAL PUMP BEARINGS
Baker SPD specifies bearings of the highest quality from
premier bearing manufacturers. The bearings are
interchangeable with other
popular 1-7/8 in. pump
models. Both the Inboard
and the Outboard
Bearings are single row
angular contact
configuration for maximum
run life. The bearings have
an eccentric locking ring design
which eliminates the need for a shrink fit
installation.
6
INJECTABLE PACKING OPTION
In our tireless effort for continuous
improvement, Baker SPD is proud to offer an
injectable packing option on our pumps. For
the 1-7/8 in. MUD HOG™ pump, this option
comes with a modified shaft comprising of a
17-4PH sleeve, shrink fitted onto the fluid end
of the shaft. The packing itself is a mixture of
non hazardous, high tech fibers and
lubricants, which eliminate the need for
external lubrication during operation. The
injectable packing thus provides a leak free
and cheaper alternative to mechanical seals
and a more maintenance friendly substitute
for the conventional packing rings. The
packing can be installed initially by
conventional means but can then be easily
replenished using a hydraulic hand gun, even
during pump operation. Ask your nearest
Baker SPD Customer Representative for
more information about this exciting product.

Baker SPD
CENTRIFUGAL PUMP PARTS (CONTINUED)
STUFFING BOX BOLTS
The Labyrinth Seal or Isolator is a two-piece device
used to isolate the Bearings from harmful
contaminants, while keeping the Bearings lubricated.
Labyrinth Seals use two different components; a rotor
and a stator. The rotor is attached to the shaft
through a ring and rotates with it, thus decreasing
shaft wear. The stator portion of the Labyrinth Seal is
stationary and press fit into the Housing. These two
pieces lock with an O-ring to form a single working
unit. This configuration, while turning, is free from
mechanical contact. The Labyrinth Seals are abrasion and corrosion resistant for longer life.
Two Stuffing Box Bolts are set up 180 degrees apart
to hold the Stuffing Box in place. The positioning of
the bolts allows the Casing to be replaced without
interfering with the Stuffing Box or hampering
removal of the Casing.
CENTRIFUGAL PUMP FRAME
The MUD HOG's frame is made from cast iron for
strength and durability. The frame has been
designed to withstand high piping loads that can
adversely affect bearing life. The MUD HOG™ frame
is built to handle various applications and working
conditions.
MECHANICAL SEALS
Mechanical Seals are available for the 1-7/8 in. Centrifugal Pump. However, there is a shaft failure history
of the mechanical seal configuration, caused by the
inherent bending and vibration that come with a
smaller diameter shaft. That is why mechanical seals
are not recommended on this pump. Assemblies
with Mechanical Seals are NOT warranted.
GENERAL INFORMATION
CENTRIFUGAL PUMP LABYRINTH SEALS
JACK BOLTS
The MUD HOG™ uses two [2] 3/4 in. stainless steel
Jack Bolts to assist in the replacement of the Casing.
There is a build up of material between the Casing
and Stuffing Box during normal operation. This build
up can make it difficult to remove the Casing.
Conventional pry bars, crow bars and other tools do
not distribute an even force and may cause bending.
The Jack Bolts allow an even distribution of pressure
to the Casing for ease in removal.
STAINLESS STEEL CASING NUTS
Casing replacement has been made easier by
utilizing stainless steel Casing Nuts. Stainless steel is
more corrosion resistant than conventional steel. The
use of stainless steel material minimizes the need for
frequent replacement of the Casing Nuts which are
otherwise worn out by rust and/or removal tools.

PUMP SIZING
HOW TO SELECT YOUR BAKER CENTRIFUGAL PUMP
1. Before sizing your Baker pump, one needs to know the following:
1.1 The pump speed which depends on the kind of drive that will be coupled to the pump, (i.e., 3500, 1750
or 1150 RPM for 60 Hz motor or 3000, 1500 or 1000 RPM for 50 Hz motor).
1.2 The Total Head (TH) required which is the summation of Vertical elevation Head (He), and Friction head
(Hf), (i.e., TH = He + Hf + any head required at of the end of piping).
Use negative suction head when the source of supply is above the pump.
1.3 The flow requirement in GPM or (m3/hr).
1.4 The specific gravity of the fluid or weight of the fluid to be pumped, such as the mud weight, in lb/gal.
2. After you get all of the above data, refer to the Baker pump curves and obtain the following information.
2.1 Find the required flow rate on the bottom or top scale, depending on whether you want to measure your
Flow rate in GPM or (m3/hr), respectively, and draw a straight line up or down.
2.2 Find the Total Differential Head at the left or right hand scale, depending on whether you want to
measure your Total Differential Head in Feet or (meters), respectively, and draw a straight line to the
right or left.
2.3 Locate the intersection of the above two lines and pick the nearest larger Impeller size. For speeds
below 2,900 RPM select Impeller size to next larger 1/4 in. diameter and for speeds above 2900 RPM
select Impeller to next larger 1/8 in. diameter. Also a set of horsepower lines gives you the horsepower
requirement for pumping water. It is best to choose a motor size larger than the minimum required. If
you pump fluid other than water, you have to adjust the required HP (kW) by multiplying the specific
gravity to the HP (kW) rating based on water.
Net Positive Suction Head means the useful pressure existing at the inlet of the pump to push the liquid into
the impeller vanes. It is measured in feet (meters) of Head and is called NPSH Available (NPSHA). NPSH
Required (NPSHR) is read from the pump curve at the designed pump impeller RPM and flow rate. NPSH
on the curve is the minimum NPSH that will prevent vapor bubbles from forming and causing cavitation.
A number of rigs run into NPSH problems which are due in part to high mud temperatures and poor suction
design. That is why it is very important to check your Net Positive Suction Head (NPSH).
NPSHA = Ha ± He - Hf - Hvp
Where:
Ha = atmospheric head (ft)
He = elevation head (ft)
Hf = friction head (ft)
Hvp = Vapor pressure of fluid at pumping temperature (ft). Refer to Page 29.
The NPSHR as shown on curves is the minimum NPSH required by pumps. If the NPSHA is larger than
NPSHR; the pump is all right. If the NPSHA is less than NPSHR, then the pump will cavitate. In such a case,
some or all of the following changes to the suction conditions might be necessary:
1.
2.
3.
Reduce flow rate
Increase suction pipe size
Lower pump speed

5. Pump Terms
5.3 Pressure of Head in Feet (meters)
When the pump is running, pressure will build up. Pressure developed by the Centrifugal Pump is
always specified as Head in Feet or (meters) of liquid. The relation between PSI and head is shown in
4.1 - 4.2.
5.4 Centrifugal Pump Rotation
You have to stand at the drive end to determine the pump rotation. A right-hand rotation pump turns
clockwise looking from the motor end. The MUD HOG™ 1-7/8 in. has a right-hand rotation.

Baker SPD
INTRODUCTION
This manual contains instructions for the installation,
operation, and maintenance of the Baker SPD MUD
HOG™ 1-7/8 in. Centrifugal Pump. After going
through this manual, if you feel that some of your
questions or situations that you are dealing with, have
not been addressed, please contact your local Baker
SPD Distributor or Salesman for further assistance.
Baker SPD's MUD HOG™ 1-7/8 in. is a pump
designed to replace some older and existing 1-7/8 in.
pumps, with a similar but superior product. We have
designed this pump keeping in mind a longer life,
reliability and easier maintenance. Some of its outstanding features that contribute towards its
popularity and success are:
1. Stainless steel shaft
2. Stainless steel casing nuts
3. Grease or Oil lubricated bearings
4. Leakage and contamination
prevention through labyrinth seals
5. Stainless Steel Jack Bolts for easy
removal of casing
It is very important to closely follow proper installation,
operation and maintenance guidelines in order to ensure a smooth and efficient pumping operation and
longer equipment life.
GENERAL INSTRUCTIONS
1. The motor/driver must operate the pump in a manner that the rotation of the pump impeller when
viewed from the suction (front) side of the pump is
COUNTER-CLOCKWISE. The pump must not be
operated in the reverse direction if damage to the
pump is to be avoided.
2. The suction and discharge valves must not be
completely closed when operating the pump.
3. The packing should be adjusted in a manner that
a small amount of leakage remains for lubrication
and cooling purposes.
4. For drilling mud operations, care must be taken to
prevent seepage from the packing to dry out and
coagulate in the areas of the inboard labyrinth
seal and the slinger.
5. Do not operate the pump outside its designed performance envelope.
SECTION A: INSTALLATION
Compatibility
The MUD HOG™ 1-7/8 in. has been designed to ensure that it can replace existing pumps of the same
nominal size. To this end, its mounting and overall di-
48
MAINTENANCE MANUAL
mensions have been selected to match up to the existing bases, piping, couplings etc.
Location
To eliminate the need for priming, the pump suction
should be at a lower level than the level of the liquid
in the supply tank/reservoir.
Foundation
It is recommended to pour a concrete foundation on a
solid base and it should be big enough to support the
whole pump unit. The rigidity of the base plate will
play an important role in damping out structural
vibrations. The foundation must be thick enough to
adequately support the unit. Refer to Hydraulic
Institute's Standard ANSI/HI 1.4-2000 for guidelines
on this subject. Care must be taken to level the base
plate in a horizontal position. Also, when the application dictates the use of a fabricated base, the foundation design must account for it properly, so that it can
effectively dampen the resulting resonant vibrations.
Alignment
For any rotating machinery, the alignment of power
transmitting and power consuming parts is critical for
its safe and long lasting service. Even if the motor and
the pump were aligned before shipping, it is very important to check the alignment after installation to ensure that the arrangement has not moved during
transportation or handling. We cannot overemphasize
proper alignment since it can mean the difference between a smooth and long lasting pump operation as
opposed to high vibrations and even failure of bearings, coupling, pump or the motor. It should be noted
that one must not try to align the pump and the motor
until its flange and mounting bolts have been tightened.
To perform the coupling alignment with dial indicators,
which are the instruments of choice for such procedures, the dial indicator is attached to one coupling
half with the indicator dial button resting on the outside diameter (OD) of the other coupling half. This will
give the offset misalignment between the two shafts.
In order to find out the angular misalignment, let the
dial indicator button ride on the face of the other coupling half, instead of its OD. A TIR of 0.005" or less is
usually considered acceptable by most manufacturers. If the TIR is more than that, it can be adjusted by
loosening the pump or driver mounting bolts, adding
or removing shims accordingly and then tightening
down the bolts again. See figures 1 and 2 below.

More information on coupling alignment can be found
in the Hydraulic Institute's Standard ANSI/HI 1.42000.
Piping
Figure 2: Angular Alignment with a Dial Indicator
For situations where a dial indicator is not available,
one can use a straight edge to perform a reasonable
alignment. This method works better when the coupling has a rubber or a flexible drive element.
To check for offset misalignment, place the straight
edge on the OD of the couplings. If they are aligned
there will not be any gaps under the straight edge. A
max gap of 1/64 in. is allowed. This procedure should
be repeated for at least one more location on the circumference of the coupling 90 degrees from the first
position.
To check for angular misalignment, the two coupling
mating faces should not have a variation in the gap,
all around the faces. A maximum variation of 1/64 in.
is permissible. See figures 3 and 4 below.
1/64 in.
Maximum Gap
It is important that the piping should line up to the
pump without it having to be drawn closer by tightening the companion flange bolts. Also, the pump
should not have to support the weight of the piping.
For this to happen, it is better to have the piping anchored independently but as close to the pump as
possible. It should also be pointed out that the piping
should not be connected to the pump until the grout
has hardened and after the motor and pump mounting
bolts have been tightened.
Suction Piping
Suction piping can not only play a critical role in causing vibration and cavitation in centrifugal pumps, but
can also be responsible for causing packing and mechanical seal failures as well as putting extreme loads
on the bearings. It is therefore very important that the
size of the suction piping be at least the same or larger than the suction port of the pump.
To eliminate air pockets in the suction line, it is beneficial for the suction line to have a gradual slope down
to the supply tank or source.
In order to have a relatively turbulence free flow into
the pump, it is good practice to have a straight length
of pipe, at least twice its diameter in length e.g., a
6-inch suction pipe should have at least one foot of
straight pipe just before the pump.
Figure 3: Offset Alignment with a Straight Edge
In situations which might require a flexible hose to be
used in the suction line, it is imperative that such a
49
MAINTENANCE MANUAL
It is recommended that the flow through the pump
should not be controlled by adjusting a valve in the
suction line. However, this does not preclude the use
of a suction line shut off valve to be used when the
pump has to be inspected or removed for maintenance purposes.
Baker SPD
flexible hose be of the non-collapsing type, since it is
not uncommon to have suction pressures which are
below atmospheric pressure. In such a scenario,
there is a real possibility of starving the pump and
thus causing it to overheat.
Discharge Piping
Like the suction piping, a shut off valve should be
used in the discharge piping as well, to enable the removal of the pump for maintenance purposes. A throttle valve can be used in the discharge line to operate
the pump at it is design point, if the exact operating
conditions are not known.
In case of a closed pressurized loop, it is necessary to
have a check valve between the pump and the throttle
valve, to prevent the product from flowing back
through the pump. In the absence of the check valve,
such a circumstance can cause the impeller to come
loose and cause damage to the pump and also result
in leakage beneath the shaft sleeve.
SECTION B: PREPARATION
FOR OPERATION
Before starting the pump, it is good practice to always
go through the following simple checks;
1. Check for impeller's free rotation by turning the
shaft by hand.
2. Make sure that the suction line and the pump are
full of fluid and that the suction valve is fully open.
3. Slightly open the discharge valve and then open it
fully once the pump is running.
Preliminary Lubrication
Our standard pumps come pre lubricated with grease
(oil lubrication is available as an option). The operators/customers do not have to worry about lubricating
the pump for the first year of operation. At that time,
the pump can be lubricated through the outboard and
inboard bearing cover lubrication fittings.
Usually, labyrinth seals are provided at both bearing
ends, and they serve to keep the temperature from
rising, by also acting as vents. But in cases where the
labyrinth seals are not provided, air vent is used. The
air vent must be kept clean.
Mechanical Seal Pumps
It is vital that these pumps are never started dry otherwise it will cause irreparable damage to the seal
faces. The factory installs and adjusts the mechanical
seals before shipping the pumps. The seal models
50
MAINTENANCE MANUAL
currently being provided with the MUD HOG™
1-7/8 in. do not require external flush.
Pumps with mechanical seals come with 3 rings of
backup packing which should be kept completely
loose until a seal failure occurs. Only then should they
be tightened down to prevent leakage.
Packed Pumps
When starting packed pumps, the packing should be
loose and the packing gland nuts should only be hand
tight. Once the pump starts running, slowly tighten the
packing down. Make sure that there is some leakage
through the packing, otherwise it will overheat and
fail.
If outside flushing is required on either pump models,
the flush lines should be connected and checked for
flow through them, before starting the pump
Pump Rotation
The direction of rotation of the pump should always be
checked only when the motor is uncoupled from the
pump. Once the direction of rotation of the motor shaft
has been ascertained, the pump can be coupled with
the motor.
Pump Priming
To prevent damage to the mechanical seals or packing, there must be liquid in the suction line and the
casing, before the pump is started. Fill the suction line
with the liquid and vent out any air that might be
present in the line. The discharge valve should be
barely open when the pump is started and only after
the flow and pressure have stabilized that it should be
adjusted to the required flow conditions. If the pressure fails to build, close the discharge valve and then
reopen it to build discharge pressure. If flow difficulties continue, it may be an indication of improper installation or pump selection.
Operators must not run the pump with the suction
valve closed under any circumstances, as it will immediately overheat the pump and cause major damage to various components.
Also, running the pump with the discharge valve
closed should be allowed only for short durations as
the energy being imparted to the pumped product by
the impeller, will raise the temperature. If for some
reason there is a need to keep the discharge valve
closed for an extended length of time, then it is recommended to run a small (Ø0.25"or Ø0.50") line, starting
Baker SPD
MAINTENANCE MANUAL
between the pump and the discharge valve and going
back to the fluid supply tank.
SECTION C: OPERATION
Operating Condition Envelope
This section only applies to pumps which do not have
any external insulation and are exposed to the room
temperature.
The maximum safe working pressure for cast iron is
175 psig at 150°F or 150 psig at 250°F. The conditions in between can be accordingly calculated.
Whenever a high temperature (150°F plus) fluid is being pumped, cooling water should be passed not only
through the lantern ring but also over the exposed
shaft, so as to dissipate the heat being generated at
the labyrinth seal or lip seal and the bearings.
side hole. This will indicate that the level of oil is correct. Adding more oil than recommended can actually
be harmful to the pump.
Grease Lubrication for Bearings
The outboard and inboard bearing covers are provided with a grease fitting. It is recommended to add five
shots of grease through the grease port at least once
every six months, after the first year of service.
Grease Fitting
Documentation
It is always helpful to maintain a documentation history of the pump as it can improve our response time to
help you. To this end, we provide a nameplate on
each pump frame which contains some information
which can help us identify the pump quickly. But in addition to that, it would be helpful to keep a record of
the following information;
1. Motor horsepower
2. Operation frequency
3. Maintenance records and pertinent information on
any replacement parts.
Lubrication
Your MUD HOG™ comes lubricated with grease
when it is shipped from the factory and it does not
need to be lubricated more than once per year. The
recommended grease is Lubri Plate 1200-2. When
using different types of grease, care should be taken
to use only those types of grease which are well suited to operate with each other.
Oil Lubrication for Bearings
Oil lubrication for bearings is available as an option
but the pumps must be mounted in a horizontal position for oil lubricated pumps to work. This option is
typically exercised when it is desired to lower the
bearing temperature and hence reduce its wear.
Grease Lubrication for Packing
For packed pumps, the stuffing box cover comes with
a drilled hole for lubricating the packing rings. It is fitted with a grease fitting. It is recommended to lubricate the packing rings at least once a day. Baker SPD
offers an optional self lubricating mechanism which
only needs to be filled from time to time.
Grease should be added while turning the shaft. A
good indication of the sufficient grease in the packing
is that it will start to come out around the packing
gland. If the packing rings are worn and/or the leakage is deemed excessive, a more viscous variety of
grease like the ones used in water pumps should be
used rather than the general purpose grease.
Water Lubrication for Packing
It is recommended that whenever drilling mud is being
pumped, water should be fed to the packing through
the lantern ring, not only for lubrication purposes but
also to prevent fluid being pumped from coming
through the packing rings. Such fluids can reduce the
life of the packing as well as cause abrasion of the
shaft.
51
MAINTENANCE MANUAL
It is recommended to use 10W30-non detergent motor oil. The oil can be filled through the hole provided
on the top of the bearing frame. After removing the
plug provided in the side of the frame, oil should be
added from the top until it starts to flow out from the

SECTION D: MAINTENANCE
Inspection
Refer to Figures 6-1 through 6-4 on Pages 70 and 71.
In general, whenever disassembling a pump, always
clean the grooves for the O-rings, surfaces of the gaskets, threads and bearings.
Disassembly
Before starting any disassembly, ensure that the
pump is not running and that the coupling between
the motor and the pump is disconnected. Next step
should be to drain the casing and disengage the suction and discharge piping from the pump casing. If
feasible and preferable, remove the pump completely
away from the system to a more accessible location.
The fluid end components can now be disassembled
according to the following procedure:
1. Remove the Packing Gland Halves (30) by loosening the Packing Gland Nuts (29) and then
swinging the Packing Gland Bolts (29) to the side.
2. Remove the Casing (16) after removing the Casing Nuts (20).
3. Now loosen the bolts on both the inside and outside Bearing Covers (6). The Bearing Covers
should be slid along the shaft to expose the Bearings (10a) and their Bearing Locks (10b).
4. In order to remove the Bearings (10a), the Bearing
Lock Set Screw (10c) should be loosened. Next
strike the Bearing Lock at the hole provided diametrically opposite to the hole for the Bearing
Lock Set Screw, with the help of a thin brass rod
(or a punch) and a hammer. The Bearing Lock
(10b) should be struck so that it rotates in a direction opposite to the normal operation of the Shaft
(11). The Bearing should become loose after a
quarter revolution of the Bearing Lock (10b). Remember to remove any burrs on the Shaft caused
by the Bearing Lock Set Screw, before attempting
to slide the Shaft through the Bearings.
5. The Impeller Nuts (21) on the Impeller (23) should
be removed along with the Impeller Washer (22).
The Impeller can now easily slide off the Shaft
(11).
6. By removing the Shaft (11) from the Frame (1), the
two [2] Bearings (10) and the two Bearing Covers
(6), with attached Labyrinth Seals (5), become
free. The Bearings can be removed from the
Frame by lightly tapping them, preferably with a
piece of wood.
7. Remove the Bolts (27) and the Washer (26) for
the Stuffing Box Cover (25). The Stuffing Box
Cover can now be removed from the Frame (1).
Remove the Packing Rings (28a) and the Lantern
Ring (28b) from the Stuffing Box Cover.

• Impeller:
Short of unavailability of new ones, it is always
good practice to replace all the gaskets and O-rings
during disassembly.
• Shaft and Shaft Sleeve (Optional):
A maximum run out of 0.002 is allowed on the Shaft
and the Shaft threads must be in a good condition.
The bearing seating surfaces have to be smooth
and free of scratches. If any of the above does not
seem to be in good condition, the shaft should be
replaced. Similarly the surface of the optional
sleeve should be checked for grooves and be
replaced if necessary.
• Mechanical Seal:
To prevent excessive leakage, the seal faces, gaskets and shaft sealing members must be checked
for their condition and replaced if necessary.
• Ball Bearings:
It is important that the bearings rolling elements be
smooth and not worn out. If the bearings make
noise when rotated, it is time to replace them. New
bearings should not be unpacked until it is time to
install them.
• Gaskets and O-rings:
Short of unavailability of new ones, it is always
good practice to replace all the gaskets and O-rings
after disassembly.
Assembly
It is good practice to always use new gaskets and Orings even when reassembling an old pump. The following procedure should be followed when assembling a 1-7/8 in. MUD HOG™:
1. Mount the two [2] Bearings (10a) in the inboard
and outboard recesses of the Frame (1).
2. Slip the Impeller (23) with the Impeller Key (13),
on to the Shaft (11). Now thread on and tighten the
Nuts (21) onto the Shaft after installing the Washer (22).
3. Install the Bearing Cover Gaskets (9) on the Bearing Covers (6) by using a small amount of grease
to keep them in place.
4. Install the Labyrinth Seals (5) in the Bearing Covers (6).
5. Install the Stuffing Box Cover (25) in the Frame (1)
with the help of the two [2] Stuffing Box Cover

MAINTENANCE MANUAL
Bolts (27) and the corresponding Lock Washers
(26).
6. Pass the Shaft (11) through the Stuffing Box Cover (25) bore and then slip a Bearing Cover (6) with
the Bearing Cover Gasket (9) and then the Bearing Lock (AB), on to the Shaft, in the specified order.
7. Now slide the Shaft (11) into the Frame (1). When
the Shaft comes out through the Outboard bearing
(10a), slip the Bearing Lock (10b) and the other
Bearing Cover (6) with the Bearing Cover Gasket
(9), onto the Shaft.
8. After ensuring that the Outboard Bearing (10a) is
pressed against the shoulder in the Frame (1) recess, push the Impeller (23) towards the Frame
until there is only a 0.075" gap between the back
vanes of the Impeller and the front (wear) surface
of the Stuffing Box Cover (25).
9. Once again, ensure that the outboard Bearing
(10a) is fully pressed against the recess shoulder
in the Frame (1). Then turn the Bearing Lock (10b)
in the direction of rotation of the Shaft (11) to lock
the Bearing in place.
10. Now tighten the Bearing Lock Set Screw (10c).
11. Push the Inboard Bearing (10a) against the recess shoulder and then pull it back out about 0.06"
to allow for axial expansion due to temperature
variation. The Bearing Lock (10b) on the Inboard
Bearing can now be turned in the direction of rotation of the shaft to lock it in place.
12. Tighten the Bearing Lock Set Screw (10c).
13. Both the Bearing Covers (9) can now be tightened
into place with the help of the Bearing Cover Bolts
(8).
14. Drive the Casing Studs (19) into the Casing (16)
and then install the Casing on the Frame (1).
Make sure that the Casing has the Casing Gasket
(18) installed in it. Tighten the Casing Stud Nuts
(20) by applying 140 ft-lb of torque on the nuts.
15. The Impeller Front Clearance should now be
checked. It should be about 0.025".
Stuffing Box and Components
Note: Since packing can burn easily if it is too tight
around the rotating element, so once the packing has
been pushed and seated in, the Packing Gland Bolts
(29) can be loosened and then hand tightened only.
This is the recommended condition to start the pump
in. Once the pump has been running for a little while,
one should go back in and tighten the Packing Gland
Bolts so that there is only 10-15 drops of leakage per
minute. It is important to remember that if a Packing
Ring does burn, it will never seal properly again
GENERAL OPERATING AND
STORAGE INSTRUCTIONS
Some of the important factors to watch for, while operating a pump, are:
1. The packing should not be over tightened as it will
become hard and brittle and will fail to perform its
function. But it is also important, especially when
a water flush system is being employed to lubricate the packing rings, that rings be not too loose.
That can result in flush water seeping into the drilling mud and changing its density. This situation
can also arise due to a gap between the shaft and
the packing, which results due to the whirling of
the shaft about its own axis during pump operation
and thus causing deformation of the packing. This
predicament can be solved by either manually
shutting off the water whenever the pump is not
running or installing a solenoid valve for this purpose.
2. Another factor that should be controlled to limit the
amount of water from getting into the drilling mud
is the pressure of water for the flush system. Pressure as small as 5 psi is usually enough to provide
the required lubrication for the packing rings. A
pressure regulator should be preferably incorporated into the water flush system for this purpose.
3. Bearing failure is the biggest contributor to pump
maintenance costs. So it is imperative that care be
taken not to run the pump if the bearing condition
53
MAINTENANCE MANUAL
1. The packing rings (27) will usually be either of the
Teflon® or King type.
2. Make sure that the Stuffing Box Cover ID is clean,
smooth and free of any burrs and scratches.
3. Grease should be applied to all the packing rings.
4. Insert three [3] packing rings, taking care to align
skives in the rings 180 degree apart and the skive
on the first ring on the bottom side. In case of King
packing, install the rings such that their lips are
facing the suction side of the pump.
5. The lantern ring should be installed next, making
sure that the split in the lantern ring is oriented vertically.
6. The remaining two [2] rings should now be installed such that the skive in the last ring comes
on the bottom side. However, in case of King
Packing, the final King ring should be mounted
such that the lip is facing the coupling end and it's
skive is at the top. The last square ring of packing
can then be installed with the skive pointing downwards.
7. The Packing Gland Halves (30) should now be put
it place and pressed in slightly by tightening the
Packing Gland Bolts (29).
Baker SPD
is suspect. A quick check that can be easily performed is to estimate the temperature of the pump
housing by placing a hand on it. Usually if a person can comfortably keep his/her hand on the
pump housing for a little while then the temperature is not more than 150°F. If the temperature
seems more than that, then the chances are either, that the bearings have started to fail or that
there is a lack of lubrication for them. Replacing
bearings at this stage is more cost effective than
waiting longer and then having to replace a number of other parts as well.
4. One of the most common reasons for bearing failure is misalignment between the pump and the
motor. Hence it is very important to check alignment not only before starting the pump for the first
time but to also do it periodically.
5. Care should be taken not to increase the suction
line velocity beyond 10 ft/sec because that can result in turbulence as well as cavitation. These conditions will adversely affect the efficiency and the
life of the pump, respectively
6. Perhaps the most important factor for predictable
pump performance is the Available Net Positive
Suction Head (NPSHA). Simply put, it means that
the height of the fluid in the supply tank above the
suction level of the pump should be enough to
prevent the fluid from entering the pump at a pressure which is below its vapor pressure at that temperature. If such flow conditions cannot be
avoided, cavitation occurs which is the boiling of
that fluid at the operating temperature and then
54
MAINTENANCE MANUAL
the bubbles being created during that boiling process implode and damage the various pump and
system components. Thus to prolong the life of
the pump always ensure that the pump has the
recommended NPSHA.
7. In case of indoor storage, it is desirable to avoid
temperature extremes, excessive moisture and vibrations.
8. It should be standard procedure to check the resistivity of motor windings at the time of placing
them in storage and again when it is time to take
the motor out and use it. A difference of more than
50% necessitates the drying of these windings before the pumps operation.
9. Whenever pulling the pump and the motor out of
storage, it is recommended to remove all the old
grease from the bearings and replenish them with
fresh new grease.
10. It is also recommended to manually turn the shafts
of the motor and the pump at least once every two
months.
11. If the pumps are to be stored outdoors for an extended period of time, it is good practice to properly seal off the suction and discharge openings,
to prevent rust from attacking the pump casing
and impeller.
Note: A written record of all the storage procedure
and actions should be maintained.
