RO pump

It adds pressure needed to perform treatment function and help to move treated water from storage tank to the point of use such as faucet

There are two types of pump use in reverse osmosis system

Booster pump-raise water pressure as it enters the RO unit

Delivery or demand pump – move filtered water from storage tank to the appliance such as faucet, refrigerator, and ice maker.


In the market, there is an electric pump and permeate pump.

Electric pump requires electricity to operate while permeate pump uses water pressure to increase pressure needed.

Permeate pump not only saves energy it reduces the water required to flush membrane. For instance, instead of using four gallons to produce one gallon of water, RO system using permeate pump waste one gallon to produce one gallon of filtered water. You need two gallons of contaminated water to produce one gallon of pure water.

Aquatec AQUATEC-ERP-1000 Permeate Pump

Looking for energy saving device, AQUATEC-ERP-1000 Permeate is a non-electric pump. It utilizes turbine pump that uses the pressure of the waste water to pump clean water into the storage tank.
