3.4.2 Pressure-temperature ratings
The maximum allowable discharge pressure is
6.9 bar (100 psi) from -29 to 176˚C (-20 to 350˚F).
3.4.3 Suction pressure limits
Suction pressure is limited only by the pressure
temperature ratings of the pump. Specific gravity is
limited to 2.0.
3.4.4 Minimum continuous flow
The minimum continuous flow (MCF) is based on a
percentage of the best efficiency point (BEP). Figure
3-3 identifies the MCF.

4 INSTALLATION
High Silicon Iron components
If any of the components of the pump
have been made of High Silicon Iron, the following
precautionary measures should be followed:
• Use hand wrenches rather than impact wrenches
• This equipment should not be subjected to
sudden changes in temperature or pressure
• Avoid striking this equipment with any sharp blows
High Silicon Iron components
Avoid any repair or fabrication welds
on High Silicon Iron components.
4.1 Location
The pump should be located to allow room for
access, ventilation, maintenance, and inspection with
ample headroom for lifting and should be as close as
practicable to the supply of liquid to be pumped.
Refer to the general arrangement drawing for the
pump set.
