LiquaGen - Reverse Osmosis Booster Pump 150 GPD Powered only by the hydraulic energy of brine water usually lost to the drain (i.e. no electricity required). The pump forces product water into the storage tank, reducing membrane back pressure and maximizing available feed pressure Permeate Pumps can bring storage tanks up to line pressure and then shut the system down when these tanks reach capacity, eliminating the need for a hydraulic shut-off valve. Other benefits include higher delivery pressures, faster R.O. water production, superior water quality, and extended filter/membrane life.
