A Permeate Pump increases net pressure across the RO membrane by isolating the membrane pressure from the pressure in the product water tank, thereby reducing the permeate back pressure to less than 3 psi. Using a permeate pump with an automatic shut-off valve greatly increases water purity stored in the tank, eliminating TDS (Total Dissolved Solids) creep. The pump requires no electricity and is powered by energy from brine normally lost to drain. The use of permeate pump increases membrane life and pre-filter life, reduces waste water by up to 80%, and fills the tank 2 times faster than conventional units.
Our Permeate Pump Retrofit Kit includes a permeate pump, mounting clip, an automatic shut-off valve and all necessary tubing and fittings. It is available for use with existing RO or RO/DI Drinking Water Systems. Use PP-RFK-RO for RO Systems with Drinking Water Kits & use PP-RFK-DI for RO/DI Systems with Drinking Water kits.
Important Note:
-
The permeate pump is only effective when used with a bladder storage tank. Use of permeate pump does not have any advantage when being used with tanks or sumps open to atmosphere.
