VFDs for single-phase pump control
A properly selected VFD helps a single-phase pump start smoothly, reduce hydraulic shocks, and keep pressure stable. This improves pump lifetime and reduces stress on piping and fittings.

How to select a VFD for a single-phase pump
Match supply voltage/phase, motor rated current, control mode, and protection setpoints. For pressure systems, PID control is recommended. Correct acceleration and current limits are essential for reliable operation.
