(PS-10-13) Mark 3 9/16/04 2:43 PM Page 9 Pump Division Mark 3 Heavy-Duty Shaft and Bearings The Heart of the Pump: Shaft and Bearing Design Flowserve offers the largest shaft and bearing components available in standard ANSI pumps. The following comparison of a Mark 3 Group 2 power end with that of a major competitor demonstrates the benefits of heavy-duty design. Unique External Micrometer Impeller Adjustment reduces maintenance time and, most importantly, is precisely accurate. Prima 3 bearings are designed to last up to 61% longer. Table 1 Bearing Comparison Group II Flowserve I.B. Bearing 6310 Dynamic Load Rating 6078 kg (13 400 lb) O.B. Bearing 5310 Dynamic Load Rating 8709 kg (19 200 lb) Major Competitor 6309 5398 kg (11 900 lb) 5309 7439 kg (16 400 lb) Simply loosen the setscrews. Using a wrench rotate the bearing carrier counterclockwise until the impeller lightly touches the rear cover plate. Bearings (see Table 1) Greater load handling rating means extended bearing life. Extended bearing life comparison is the ratio of the load ratings to the third power or: 6078 3 I.B. = 5398 = 1.43 (+43%) 8709 3 O.B. = 7439 = 1.61 (+61%) Table 2 Deflection Comparison Group II Overhang Length Flowserve 189 mm (7.687 in) Major Competitor 213 mm (8.375 in) 43-252% greater stiffness, indicated by lower index numbers, results in improved performance and reliability. Solid Shaft Deflection Diameter Index Shaft Dia. w/sleeve Deflection Index 48 mm (1.875 in) 37 38 mm (1.5 in) 90 45 mm (1.75 in) 63 38 mm (1.5 in) 116 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. 9 © TriCom, Inc., 2004, All Rights Reserved.

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. See page 28. Low Predictable Seal Chamber pressure means longer seal life Clearance is set to the rear cover in the shop – not to the casing which is left in the piping Lowest Overall required NPSH of any standard pump In-shop Impeller Adjustment is practical as well as productive. Rear Cover wear surface versus casing means lower replacement parts costs 12 © TriCom, Inc., 2004, All Rights Reserved. Radial Vane Impeller is available for low-flow, high-head applications.

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 ANSI Chemical Process Pumps 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.

Below are a list of typical applications and some of the top customers that use Mark 3 pumps. Applications: • Chemical and petrochemical processing • Acid transfer • Brine transfer • Food and beverage processing • Hydrocarbon processing • Pharmaceuticals • Pulp and paper • Sea water • Solvents • Metal processing • Water and waste water treatment • Polymers Top Customers: • DuPont • Dow • Kerr-McGee • Cargill • Monsanto • Solutia • Merck & Co. • Eastman Chemical • Bayer • Anheuser-Busch • BASF • PPG • Vulcan Materials • Occidental Chemical • BP Amoco Some detailed applications manuals have been prepared for the Mark 3 in some specific processes. The applications include: • Corn Wet Milling and Refining • Chlor-Alkali Industries • Mineral Acids Production • PTA Production • Titanium Dioxide Production These applications manuals are reproduced below. 7-1 Mark 3 ANSI Chemical Process Pumps Section 1 Corn Wet Milling and Refining Applications __________________________________ Section 2 Chlor-Alkali Industries Applications ____________________________ Section 3 Mineral Acids Applications _____________________ Section 4 PTA Applications _____________ Section 5 Titanium Dioxide _____________ 11/04 MK3 (PRM) 11/22/04 9:40 AM Page 7-2 Pump Division Mark 3 Representative Installation Lists THIS PAGE INTENTIONALLY BLANK 7-2 Mark 3 ANSI Chemical Process Pumps 11/04 MK3 (PRM) 11/22/04 9:40 AM Page 8-1 Pump Division 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 ANSI Chemical Process Pumps 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. 11/04 MK3 (PRM) 11/22/04 9:40 AM Page 8-2 Pump Division Mark 3 Competitive Analysis THIS PAGE INTENTIONALLY BLANK 8-2 Mark 3 ANSI Chemical Process Pumps 11/04 Pump Division Mark 3 Coverage Charts FLOW – 3500 RPM (60 Hz) 0 ft 200 m 0 400 50 600 100 Mark 3 Standard Group 1 800 150 1000 1200 200 1 1400 gpm 250 m ft 1120 320 1040 300 m3/h 2 3 750 4 5 6 960 200 7 280 8 10 720 150 450 200 20 640 560 19 160 10 480 100 21 300 11 13 14 8 13 14 15 16 17 18 19 20 80 240 9 21 22 160 23 40 24 8x6-14A 0 0 0 40 60 0 80 200 3x2-8 4x3-8 2x1LF-10 2x1-10A 3x11/2 -10A 3x2-10A 4x3-10 4x3-10H 6x4-10 6x4-10H 3x11/2 LF-13 3x11/2 -13 3x2-13 4x3-13 4x3-13HH 6x4-13A Mark 3 Standard Group 3 80 4 3 1 0 20 12 7 6 2 0 11 320 16 50 400 120 12 5 9 TDH – 3500 RPM (60 Hz) TDH – 2900 RPM (50 Hz) 800 240 18 150 Mark 3 Standard Group 2 880 600 11/2 x1LF-4 11/2 x1-6 3x11/2 -6 3x2-6 11/2 x1LF-8 11/2 x1-8 3x11/2 -8 100 120 140 400 160 180 600 200 220 800 240 260 25 10x8-14 26 6x4-16 3 m /h 27 8x6-16A 28 10x8-16 1000 gpm 29 10x8-16H 30 10x8-17* FLOW – 2900 RPM (50 Hz) *Max. speed 1450 RPM 0 ft 200 m 60 200 0 400 50 FLOW – 1750 RPM (60 Hz) 800 1000 600 100 150 200 227 2800 400 4600 800 6400 1200 8200 gpm 1600 m3/h m 80 ft 300 250 18 60 TDH – 1450 RPM (50 Hz) 40 200 22 100 23 30 19 10 20 150 21 27 40 25 28 24 20 11 12 6 7 10 16 15 20 50 9 8 14 2 0 100 17 13 5 50 29 4 1 0 0 50 0 200 100 400 150 600 190 800 500 2300 800 3800 1100 5300 0 1400 m3/h 6800 gpm FLOW – 1450 RPM (50 Hz) 9-1 Mark 3 ANSI Chemical Process Pumps 11/04 0 TDH – 1750 RPM (60 Hz) SCALE 26 150 CHANGE 50 MK3 (PRM) 11/22/04 9:40 AM Page 9-2 Pump Division Mark 3 Coverage Charts THIS PAGE INTENTIONALLY BLANK 9-2 Mark 3 ANSI Chemical Process Pumps 11/04 Pump Division 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. 10-1 Mark 3 ANSI Chemical Process Pumps 11/04 Pump Division 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.

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. 11-1 Mark 3 ANSI Chemical Process Pumps 11/04 MK3 (PRM) 11/22/04 9:47 AM Page 11-2 Pump Division Mark 3 Miscellaneous Information 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. 11-2 Mark 3 ANSI Chemical Process Pumps 11/04 MK3 (PRM) 11/22/04 9:47 AM Page 11-3 Pump Division Mark 3 Miscellaneous Information 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. 11-3 Mark 3 ANSI Chemical Process 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. 11/04 MK3 (PRM) 11/22/04 9:47 AM Page 11-4 Pump Division Mark 3 Miscellaneous Information 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. 11-4 Mark 3 ANSI Chemical Process Pumps 11/04 MK3 (PRM) 11/22/04 9:47 AM Page 11-5 Pump Division Mark 3 Miscellaneous Information 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 ANSI Chemical Process Pumps 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). 11/04 Pump Division Mark 3 Miscellaneous Information Figure 11.1 Typical Torque-Speed Curve - Mark 3 Pumps 100 90 Percent Full Load Torque 80 70 60 50 40 30 20 10 0 0 10 20 30 40 50 60 70 80 90 Percent Operating Speed 11-6 Mark 3 ANSI Chemical Process Pumps 11/04 100 MK3 (PRM) 11/22/04 9:47 AM Page 11-7 Pump Division Mark 3 Miscellaneous Information Table 11.1 WR 2 and Critical Speed Values for Mark 3 Pumps Pump Size 1K1.5X1-62 1K3X1.5-62 1K1.5X1-82 1K3X1.5-82 2K3X2-82 2K4X3-82 2K2X1-10A 2K3X1.5-10A 2K3X2-10A 2K4X3-10 2K4X3-10H 2K6X4-10 2K3X1.5-13 2K3X2-13 2K4X3-13 2K6X4-13A 3K8X6-14A 3K10X8-14 3K6X4-16 3K8X6-16A 3K10X8-16 3K10X8-16H 11-7 Mass Moment of Inertia MR2 WR2 (kg-m 2) (lb-ft 2) 0.011 0.25 0.013 0.30 0.013 0.30 0.015 0.35 0.016 0.38 0.021 0.50 0.013 0.32 0.017 0.40 0.018 0.43 0.023 0.55 0.024 0.56 0.046 1.10 0.027 0.64 0.028 0.66 0.031 0.74 0.073 1.73 0.319 7.58 0.301 7.15 0.248 5.90 0.257 6.10 0.461 10.94 0.484 11.50 Mark 3 ANSI Chemical Process Pumps Critical Speed (RPM) Solid Shaft Sleeved Shaft 13080 12230 10940 13910 12940 10920 13190 12580 13190 12040 11310 8780 10920 9670 9330 7150 7970 6620 6990 7020 5930 5920 9520 8910 7970 11790 10960 9250 11190 10660 11180 10210 9590 7440 9250 8200 7910 6060 6750 5600 5880 5940 5020 5010 11/04 MK3 (PRM) 11/22/04 9:47 AM Page 11-8 Pump Division Mark 3 Miscellaneous Information Table 11.2 Standard Pump Volumes Volume Pump Size 1K1.5X1-62 1K3X1.5-62 1K1.5X1-82 1K3X1.5-82 2K3X2-82 2K4X3-82 2K2X1-10A 2K3X1.5-10A 2K3X2-10A 2K4X3-10 2K4X3-10H 2K6X4-10 2K3X1.5-13 2K3X2-13 2K4X3-13 2K6X4-13A 3K10X8-14 3K8X6-16A 3K10X8-16 3K10X8-16H Cubic Centimeters 900 1130 900 1510 1900 3410 1360 2050 1820 3180 5210 6820 2720 3180 4770 9470 41260 29530 42770 57160 Cubic Inches 55 69 55 92 116 208 83 125 111 194 318 416 166 194 291 578 2518 1802 2610 3488 Table 11.3 Unitized Self Primer Volumes Volume Pump Size 1J1.5X1US-6 1K1.5X1.5US-82 2K2X1.5US-10A 2K3X2US-10 2K4X3US-10H 2K3X2US-13 2K4X3us-13 2K6X4US-13A 11-8 Priming Liquid Only Cubic Cubic Inches Centimeters 3030 185 4540 277 6820 416 9080 554 17800 1086 17420 1063 21580 1317 21960 1340 Mark 3 ANSI Chemical Process Pumps Total Casing Cubic Cubic Inches Centimeters 3785 231 6440 393 8325 508 11355 693 21580 1317 20830 1271 26500 1617 27630 1686 11/04 MK3 (PRM) 11/22/04 9:47 AM Page 12-1 Pump Division Mark 3 Pricing for Pumps and, Optionally, Parts PRICING FOR PUMPS, MODIFICATIONS, ACCESSORIES AND PARTS All Mark 3 pumps are fully supported in PROS which includes pricing.

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.
