This revolutionary pump is powered only by the hydraulic energy of waste water usually lost to the drain (i.e., no electricity required), the pump forces product water into the pressurized storage tank. These pumps dramatically improve the efficiency of RO water production, reducing wastewater by up to 80. Benefits include higher delivery pressures, faster water production, superior water quality, and extended filter/membrane life. This pump can be ordered as a component of a new BH RO system, or can be retrofitted to upgrade existing RO systems. Has 1/4 inch quick connect fittings. Includes clip kit for mounting pump to RO membrane housing.
