Frequently asked questions

What is the Flowserve HHPX pump used for?
The Flowserve HHPX is designed for high-suction-pressure seawater reverse-osmosis desalination applications, including energy-recovery-device booster duties.
What type of pump is the Flowserve HHPX?
It is an end-suction, single-stage, radially split centrifugal pump designed for high-suction-pressure service.
What does high suction pressure mean for an HHPX pump?
It means the pump is designed to operate where pressure at the inlet is already high, such as in seawater reverse-osmosis systems with energy recovery equipment.
How do I choose the right HHPX pump?
