Variable Frequency Drives

Xylem offers Godwin Variable Frequency Drives (VFD) to automatically vary electric motor speed for Godwin Dri-Prime and Heidra pumps.

Godwin VFDs enable variable speed control to optimize system performance, increase efficiency and mechanical reliability by automatically starting and stopping electric motors using switches, transducers and SCADA remote signals. Godwin VFDs monitor motor conditions such as speed, torque, voltage, current and power, and mitigates the effects of waterhammer from startup and shutdown of pumps. VFDs allow operators to maintain wet-well level and discharge pressures. ​

Godwin VFDs also provide power savings by enabling the pump and motor speed to vary and match system demands, using only the energy required. VFD technology is ideal for applications such as drinking water distribution systems, booster pump applications, pumping into sanitary force mains and other pump applications that require a pump to match a pressure, level or flow condition.
