4 Scope The purpose of this Practice is to specify the requirements for design and manufacture of horizontal end suction centrifugal pumps. The requirements in this Practice are modifications, additions, and/or deletions (exceptions) to the requirements in ASME B The section/paragraph numbers and the associated headings used in this Practice correspond to the ones used in ASME B73.1. Since this Practice does not take exception to all the requirements in ASME B73.1, the section/paragraph numbers in this Practice may not be sequential. Data sheets PIP RESP73-D and PIP RESP73-DM, appended, may be used to select options for ordering the pumps specified in this Practice. For general water services that fall out of the limitations of this practice use PIP RESP003H. References Applicable requirements in the latest edition (or the edition indicated) of the following industry standards shall be considered an integral part of this Practice: Industry Codes and Standards American Society for Mechanical Engineers (ASME) ASME B Specification for Horizontal End Suction Centrifugal Pumps for Chemical Process American Society for Testing and Materials (ASTM) ASTM A193 - Specification for Alloy-Steel and Stainless Steel Bolting Materials for High- Temperature Service Process Industries Practices RESP002 - Design of ASME B73.1 and General Purpose Pump Baseplates REEE003 - Guidelines for General Purpose Non-lubricated Flexible Couplings Add ISO Definitions Terms used in this Practice to introduce the exceptions to the requirements in ASME B73.1 are defined as follows: Modify to Read: Introduces a requirement that modifies a requirement in ASME B73.1 Inserts requirement(s) that is/are additional to the requirements in ASME B73.1 Delete: Introduces deletion of requirement(s) in ASME B73.1 Process Industry Practices Page 2 of 11

5 3. Alternative Design 3.1 Vendor's quotation shall conform to this Practice and purchaser's addenda. At the vendor's option, an alternate quotation may be offered if the following two conditions are met: If there is a significant process or delivery advantage, a superior or more reliable pump design may be offered. The vendor shall provide the technical justification Alternate quotation shall indicate deviations from the requirements in this Practice. Complete details of deviations shall be submitted to purchaser for review. 3.2 If vendor s quotation indicates no deviations from the requirements in this Practice, it shall be assumed by the purchaser that the pump quoted complies fully with this Practice. Deviation to the dimensional standards shall be noted in the vendor s proposal and must be noted on supporting dimensional drawings. 4. Nomenclature and Definitions Minimum Continuous Stable Flow is the minimum flow at which the pump can continuously operate without exceeding vibration limits specified by this Practice Minimum Continuous Thermal Flow is the minimum flow at which the pump can continuously operate without its operation being impaired by the temperature rise of the pumped liquid Normal Operating Point is the point at which usual operation is expected Rated Point is the operating condition for the pump performance design and the primary point that is verified during the pump performance test Rated Shaft Power is the power required by the pump shaft at specified rated operating conditions, including capacity, suction and discharge pressures, specific gravity, viscosity, and all mechanical losses (seals, gears, couplings, etc.) Rated Suction Pressure is the suction pressure of the operating conditions at the Rated Operating Point Suction Specific Speed is an index of pump suction operating characteristics determined at the BEP with the maximum diameter impeller. Suction specific speed is an indicator of the NPSH3 (defined in the following equation) for given values of capacity and rotating speed and provides an assessment of the pump s susceptibility to internal recirculation. Suction specific speed is calculated by the following equation: Process Industry Practices Page 3 of 11

6 n qs (Nss) = n(q) 0.5 /(NPSH3) 0.75 where: nqs Nss = = suction specific speed, metric suction specific speed, US Customary n = rotating speed in revolutions per minute q = flow per impeller eye, in cubic meters per second (gallons per minute) at the BEP with the maximum diameter impeller = total flow for single suction impellers = one-half total flow for double suction impellers NPSH3 = net positive suction head required in meters (feet) at the BEP for the maximum diameter impeller Note: Suction specific speed derived using cubic meters per second and meters multiplied by a factor of 51.6 is equal to suction specific speed derived using U.S. gallons per minute and feet, nqs * 51.6 = N ss. The usual symbol for suction specific speed in U.S. units is N ss Shaft Stiffness Ratio is a measure of the stiffness of the pump shaft determined from the following formula: L 3 / D 4 mm -1 (in-1 ) where: L = length of shaft from center of impeller to nearest bearing (mm) (in) D = diameter of the shaft in the seal chamber (mm) (in) Note: A lower stiffness ratio means the shaft has smaller deflections, which decreases wear of the seal. For shafts made of 4140 steel, industry experience has shown that stiffness ratios lower than 2 when using mm and 60 when using inches significantly improve seal life Solid Shaft Design is a pump shaft design in which the shaft has standard dimensions without using a sleeve Throat Bushing is a device that forms a restrictive close clearance around the sleeve (or shaft) between the seal chamber and the impeller Throttle Bushing is a device that forms a restrictive close clearance around the sleeve or shaft between a seal and the atmosphere. This is typically built into seal cartridge designs. Process Industry Practices Page 4 of 11

7 5. Design and Construction Features 5.1 Pressure and Temperature Limits Temperature Limits Modify First Sentence to Read: Maximum Allowable Temperature shall be limited to 149C (300F) on foot mounted pumps to limit misalignment due to thermal growth Hydraulic Selection Criteria Head-capacity curves that rise continuously to shutoff are preferred for all applications. If parallel operation is specified, the head rise to shutoff shall be at least 10% of the head at rated capacity. The installation of an orifice plate on the pump discharge is acceptable to obtain the 10% head rise provided that it is stated in the proposal. If this option is selected, the orifice shall be supplied by the pump vendor. If an orifice is quoted, the proposal shall include the impact on the standard curves including flow, head, HP, NPSHR, and efficiency The normal operating point flow rate shall be greater than the minimum continuous flow rate specified by the vendor and less than the flow rate at the BEP for the impeller diameter selected. Comment: The Best Efficiency Point (BEP) for the furnished impeller should be between the normal and rated operating points Pumps with constant speed drivers shall be capable of a future head increase of at least 5% at rated flow rate by installing a larger diameter impeller The minimum diameter impeller supplied shall be 105% of the minimum diameter impeller indicated on the generic pump curve for the specific pump The rated pump differential head required shall be based upon the rated differential pressure and the lowest specific gravity (SG) fluid If viscosity corrections are required, head, capacity, and efficiency corrections shall be the responsibility of the pump vendor Pumps with suction specific speeds nqs greater than 215 (Nss greater than 11,000) require specific purchaser approval. If such pumps are quoted, vendor shall include in the quotation minimum continuous flow rate, maximum operating flow rate, and a users list that demonstrates experience The vendor shall state the minimum continuous flow rate for the pump and whether the minimum continuous flow rate is based on hydraulic stability or thermal limitations. The larger of the two values shall be used in establishing the pump s minimum flow Hydrocarbon correction factors shall not be used to calculate NPSH. Process Industry Practices Page 5 of 11

8 5.2 Flanges Flanges shall be designed for through bolting if possible. If alternative methods of flange connection are required, the vendor shall supply flange details in the proposal Suction and discharge flanges shall meet the requirements of ASME/ANSI B16.1 and B16.5 for parallelism of the sealing face and the backside of the flanges Flanges shall have machined faces with a µm ( microinch) Ra finish. Finish shall be serrated-concentric or serrated-spiral. 5.3 Casing Drain Connection Boss(es) Modify to Read: Pumps shall be provided with a boss on the lowest part of the casing capable of accommodating a case drain which shall not be drilled and tapped unless a drain is specified. Comment: Socketwelded and threaded case drains may not be acceptable for process fluids that cause crevice corrosion or polymerization, etc. The Purchaser shall define those applications and the type of drain connections. When a casing drain is specified: The connection shall be largest possible for that casing up to a maximum of 3/4 NPS. Ductile iron or cast iron pump case drains shall be drilled, tapped and plugged with carbon steel plugs. Alloy pumps shall be provided with either a drilled and tapped drain with plug of the same metallurgy as the casing or a short schedule 160 nipple socket welded drain connection. If a flange connection is specified, it shall terminate at the edge and within the confines of the baseplate. The piping and flange shall be of similar metallurgy as the pump casing Auxiliary Connection Boss(es) Modify Last Sentence to Read: Unless otherwise specified, the boss(es) shall not be drilled. Comment: Vent and gauge connections are normally supplied in the piping systems and not on the pump casing Jackets There are several available methods of cooling or heating specific areas of most ASME pumps. The following are examples of acceptable methods and should be available as optional features: Process Industry Practices Page 6 of 11

Jackets for cooling or heating shall be designed so as to facilitate complete drainage for freeze protection. Note: Current philosophy is that cooling jackets are susceptible to corrosion and fouling issues. Constraining the growth of the bearing outer race may lead to shortened bearing life. At the temperature limits of this Practice, cooling jackets are of limited effectiveness. Unless otherwise specified, casing bolting for ductile iron and carbon steel pumps shall conform to ASTM A193, Grade B7 and, for alloy pumps, bolting shall conform to ASTM A193, Grade B8 Class 2 or ASTM A193, Grade B7 with PTFE coating Casing Machining 5.4 Impeller 5.5 Shaft Machined angle face of the pump case for open faced impellers shall be machined out to the maximum diameter impeller of published OEM standard curves unless authorization is given by the purchaser in writing Closed face impellers shall have a case wear ring Balance Modify to Read: Impellers shall be dynamically balanced in accordance with ISO , quality grade G6.3 after trimming to the required diameter. If the ratio of maximum outside diameter divided by the width at the periphery including the shroud(s) is less than six, a two-plane spin balance shall be performed Deflection Also, shaft deflection at the seal faces shall be less than mm (0.003 inch) from the minimum flow to end of the curve. Suppliers shall provide the stiffness ratio (L 3 /D 4 ) to the purchaser. Process Industry Practices Page 7 of 11
