本规程规定了供水用150 kW（200 HP）或以上立式离心泵的设计和制造要求。注释:水服务包括冷凝水、冷却水、软化水、公用事业用水、气田水、净化水等。注释:一般水服务包括冷凝水、冷却水、软化水、公用事业用水、气田水、净化水等。本规程描述了立式离心泵及其附件的制造和性能要求。本规程适用于工作条件在以下限制范围内的泵:a.最大排放压力35 Barg（500 psig）b.最低泵送温度0°C（32°F）C.最高泵送温度150°C（300°F）d.最大转速3600 rpm注意事项:对于这些条件以外的服务以及ANSI/ASME泵的能力范围内的服务，建议购买泵时使用PIP RESP73V。 注释:对于ANSI/ASME泵能力范围内的服务，使用PIP RESP73V。本规程涵盖的泵分为扩散器和蜗壳、独立排放悬臂泵和立式泵。立式直列泵和潜水泵具有特殊的设计特点，不包括在本规程的范围内。消防水泵包含在NFPA 20中，不包含在本规程中。

This Practice provides requirements for design and manufacture of vertical centrifugal pumps of 150 kW (200 HP) or greater used for water services.Comment: Water services include condensate, cooling water, demineralized water, utility water, produced water, treated water, etc.Comment: General water services include condensate, cooling water, demineralized water, utility water, produced water, treated water, etc.This Practice describes manufacturing and performance requirements for vertical centrifugal pumps and their accessories.This Practice covers pumps with service conditions within the following limits:a. Maximum discharge pressure 35 Barg (500 psig)b. Minimum pumping temperature 0°C (32°F)c. Maximum pumping temperature 150°C (300°F)d. Maximum rotational speed 3,600 rpmComment: For services outside these conditions and those that fall within the capabilities of ANSI/ASME pumps, it is recommended that PIP RESP73V be used for purchase of pumps.Comment: For services within the capabilities of ANSI/ASME pumps, use PIP RESP73V.Pumps covered by this Practice are classified as diffuser-and-volute, separate discharge cantilevered, and vertical can.Vertical in-line and submersible pumps have special design characteristics and are not included in the scope of this Practice.Fire water pumps are covered by NFPA 20 and are not covered by this Practice.
