Installation Configurations
High Pressure Centrifugal Feed Pumps
• A throttle valve is needed to regulate feed pump discharge pressure.
•
The throttle valve should be located between the feed pump and the HPB feed inlet.
•
If the feed pump speed is controlled by a variable frequency drive (VFD), a throttle valve is
not required.
NOTES:
Minimum distance between high pressure pump and throttle valve is pipe dia x 3.
