SHURflo 8000 Series RO Pumps are the most widely used pumps for RO. They are ideal for high pressure / low flow applications with low amp draw. They can be mounted in any position, are compact, and are designed for long trouble-free life.
The 6800 series water pressure booster pump is designed to boost water pressure to an RO systems that produce less than 50 gpd (gallons per day). RO Systems rated for more than 50 gpd should use the 8800 series booster pump.
The 8800 series water pressure booster pump is designed to boost water pressure to an RO systems that produce more than 50 gpd (gallons per day). RO Systems rated for less than 50 gpd should use the 6800 series water booster pump.
Boosting pumps are to be used in applications where the normal water pressure feeding a system is low and needs to be increased - where you want to boost water pressure. The typical reverse osmosis (RO) system requires at least 50 psi feeding the system in order to function properly. If the water pressure feeding an RO system is less than 50 psi, the system will produce less water and at a lower quality.
The water pressure boosting pumps are designed specifically for increasing the water pressure (boost water pressure) to pre-water treatment (RO boost) applications. Most booster pumps require a pressure switch and transformer.
