VARIOspeed® VFD
The VARIOspeed® variable frequency drive (VFD) is designed for constant pressure control applications, including booster pumps, deep well submersible pumps, and irrigation pumps.
As flow and head conditions change in the pumping system, the VARIOspeed® VFD is able to automatically control the pump speed and maintain a constant discharge pressure. The desired set pressure is set on the VFD keypad. The pressure transducer measures the pump discharge pressure.
