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 rpm

Comment: 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.
