    The VARIOspeed variable-frequency drive (VFD) is designed specifically for pressure control applications. As the flow and head conditions change in the pumping system, it is able to automatically control the pump speed and maintain a constant discharge pressure. The desired set pressure is configured with the user-friendly VFD keypad. The pressure transducer measures the pump discharge pressure.
