How Does a Vfd Work on a Pump

Variable frequency drives are used for adjusting flow or pressure to the actual demand. They control the frequency of the electrical power supplied to pumps or fans. Significant power savings can be achieved when using a VFD pump. … It controls the frequency of the electrical power supplied to the motor.

How does a VFD affect a pump?

VFDs (Variable Frequency Drives) can achieve reduced flow by providing variable speed pump operation. This results in reduced system pressure and operation near the pump’s Best Efficiency Point. In addition, maintenance costs might be reduced.

Can VFD control pressure?

The VFD regulates water pressure as demand fluctuates, and the input power required by the pumping system is minimized. Simply put, the VFD will monitor the pressure and draw just enough power to ensure that the system maintains demand.
