Scope 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. 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 Deutsches Institut fur Normung (DIN) DIN Testing in a Saturated Atmosphere in the Presence of Sulfur Dioxide 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 12

5 2. Alternative Design 2.1 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, 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. 2.2 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 dimension drawings. 3. Nomenclature and Definitions Minimum Continuous Stable Flow is the minimum flow at which the pump can operate without exceeding vibration limits specified by this Practice Minimum Continuous Thermal Flow is the minimum flow at which the pump can 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 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 Shaft Stiffness Ratio is a measure of the stiffness of the pump shaft determined from the following formula: L 3 / D 4 ( 1 / mm ) where: L = length of shaft from center of impeller to nearest bearing (mm) D = diameter of the shaft in the seal chamber (mm) Note: A lower stiffness ratio means the shaft has smaller deflections, which decreases wear of the seal. For shafts made of 4140 steel, industry Process Industry Practices Page 3 of 12

6 experience has shown that stiffness ratios lower than 60 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 (or packing) 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. 4. Design and Construction Features 4.1 Pressure and Temperature Limits Pressure Limits Modify First Sentence to Read: The Maximum Allowable Working Pressure of the casing, including the stuffing box and gland, shall be at least as great as the pressure-temperature rating of ASME/ANSI B16.1 Class 125 or ASME/ANSI B16.5 Class 150 flanges for the material used and shall be equal to or greater than the maximum discharge pressure at maximum temperature. Maximum discharge pressure shall be limited to 19 barg (275 psig) or the manufacturer s pressure and temperature design limits of the specified material, whichever is lower. Comment: The flange rating for some material will limit the pressure below 19 barg (275 psig) at temperatures above ambient. Maximum suction pressure shall be limited to 5 barg (75 psig). Comment: For high specific gravity fluids, maximum suction pressure may be limited to less than of 5 barg (75 psig) Temperature Limits Modify First Sentence to Read: Maximum Allowable Temperature shall be limited to 149 C (300 F) 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 shut-off 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 Process Industry Practices Page 4 of 12

7 in the proposal. If this option is selected, the orifice shall be supplied by the pump vendor. When 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 new 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. These corrections shall be calculated in accordance with Hydraulic Institute Standard. Alternate correction factors may be used with customer approval Pumps with suction specific speeds n qs greater than 215 (N ss 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 12
