Permeate Pump Kit ERP-500

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, including the WP-5, WP-4V or the RO-Pure. This Kit Includes 1/4 IN and 3/8 IN adapters.

Powered only by the hydraulic energy of brine water usually lost to the drain (i.e. no electricity required), the Permeate Pump forces product water into the storage tank, reducing membrane back pressure and maximizing available feed pressure. These pumps dramatically improve the efficiency of R.O. water production, reducing wastewater by up to 80%.

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.
