The Variospeed 3R controller is designed to control a three phase pump in constant pressure control applications including booster pump, deep well submersible pump, and irrigation pump applications. As flow and head conditions change in the pumping system, the VFD is able to automatically control the pump speed and maintain a constant discharge pressure. The desired set pressure is entered on the door mounted display. The pressure transducer measures the pump discharge pressure. Not for use with sewage pumps.
