Pump Control Systems

Pump control systems are used to achieve energy efficiency. They control the pump's variable capacity mechanism with electric signals to govern both pressure and flow.
In recent years, attention has turned to systems that deploy AC servo motors to drive the pump and to control rotation frequency. Controlling the pump's rotation frequency makes it possible to supply power to rotate the motor only when needed, improving energy efficiency.
