When should I use a booster pump?

Water pressure is important for running a filtration system. It is the pressure of water that forces the water through the membrane for purification and flushing away the rejected solids. Low water pressure will result in reduced production and premature fouling of the membrane.

The ideal pressure for operating a small RO System up to 300 gallons per day is 60 PSI and for larger systems 100 PSI is optimum. Pressure below 40 PSI is generally considered insufficient and can be enhanced using a pressure booster pump.

A booster pump is used to increase inlet pressure to the RO membrane. RO membranes require a minimum of about 40 PSI to operate most water supplies meet this minimum requirement. Should you plan to use your RO system where low water pressure is a problem, using a booster pump is something that you may consider.

Even for applications with sufficient water pressure a booster pump can greatly benefit your RO System. Booster pumps will increase pressure which in turn increases the efficiency of an RO membrane. Booster pumps are cost effective through increased RO performance. The result will be much faster production of filtered water and less wastewater.
