VFD (Variable Frequency Drive)

Variable frequency drives are used to control the speed of a 3-phase motor by changing the frequency. Changing the speed of the motor changes the flow rate and discharge head of the pump to better meet the application performance requirements. This allows the pump to run more efficiently and eliminates the need for a throttling valve. VFDs are sized based on the horsepower (or kilowatts) of the motor and the available supply voltage.
