The Permeate Pump operates as a non-electrical energy recovery device which dramatically improves the efficiency of RO systems. This kit will fit a standard 4 or 5 stage unit, the WP-5, WP4-V or the RO-Pure. This Kit Includes 1/4 inch and 3/8 inch adapters.
Using only the available energy from the brine water (i.e. no electricity required), the pump forces the purified water into the storage tank. This process effectively reduces the membrane back pressure to less than 5 psi and allows the membrane to maximize its use of the available feed pressure.
The Permeate Pump can be easily retrofitted to upgrade virtually any existing RO system. The pump eliminates the need for hydraulic shutoff valves and can be used to replace booster pumps in well water applications.
