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 within the capabilities of ANSI/ASME pumps, use PIP RESP73H.

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:
