Aquatec ERP-500 Permeate Pump for up to 75 GPD

The Aquatec ERP-500 Permeate Pump will bring storage tanks up to line pressure, then shut the system down when the tank reaches capacity, removing the need for a hydraulic shut-off valve. Permeate pumps also deliver faster RO water production, higher delivery pressures, superior water quality, and extended filter/membrane capacity. Features: No electricity required. The Aquatec ERP-500 is powered by hydraulic energy from the brine water that is usually lost to the drain. No loud clicking or gurgling sounds. This pump is specifically designed for residential applications where noise is a key concern. The ERP-500 includes a specially designed insert . The Permeate Pump pushes more purified water into the storage tank, reducing membrane back pressure, therefore maximizing available product tank pressure (up to 95% of feed pressure). Improved efficiency. This pump dramatically improves the membrane's production, reducing waste-water by 80% or more. Basically, if an R.O. system require
