Description / Abstract:
This Practice describes manufacturing and performance
requirements for horizontal 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 RESP73H be used for purchase of
pumps.
Pump types covered by this Practice are broadly classified as
overhung or between-bearings.
The following pump types are not included in the scope of this
Practice:
a. Close coupled (i.e., impeller mounted on the motor shaft)
b. Two-stage overhung
c. Double suction overhung
Fire water pumps are covered by NFPA 20 and are not
covered by this Practice.
Purpose
This Practice provides requirements for design and manufacture
of horizontal 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.
