ABSTRACT:
A booster pump for a reverse osmosis water purification system. The booster pump has a spring return piston that is stroked by the pressure of feedwater. The pump also has a pair of solenoid control valves that control the flow of feedwater into and out of the pump to move the piston between stroke and return positions. The control valves are switched by a detector switch which detects when the piston reaches the fully stroked and return positions.
