High-Pressure Pumps
Pumps that deliver the pressure needed to drive feed water through RO membranes.
Product
Overview
High-pressure pumps raise feed water to the operating pressure of the RO train — moderate for brackish water, much higher for seawater. Multistage centrifugal and positive-displacement designs are used, with duplex and super-duplex stainless steels for seawater duty and integration with energy-recovery devices on larger plants.
