VARIOspeed® LCD DRIVE

5HP - 150HP Constant Pressure Applications

Variable Frequency Drive for pressure control applications.

The VARIOspeed® LCD Drive has been factory pre-programmed for specific pressure control applications. 

As flow and head conditions change in the pumping system, the VARIOspeed® LCD Drive 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.
