RST - Electric Pump Systems

These electric powered pump systems control the speed of the motor/pump to provide the pressure and flow required. Prior to the existence of variable speed drives you either had to use expensive single stage pumps, or a pressure reducing valve, such as a Clayton valve. Whichever of these two systems were adopted, they still ran the motor/pump at full speed – regardless of what pressure and flow was required. With the a variable speed drive panel, the motor is turned at the speed that is needed and no more – rather like an engine driven pump.
