If I put a higher speed motor on my centrifugal pump, will it pump more?
It will pump more, but it will likely overload the motor. If you double the rotational speed of the motor from 1800 RPM to 3600 RPM, the horsepower required by a centrifugal pump actually increases by a factor of eight. Increasing the pump speed may also pressurize the pump beyond a safe working pressure and overload the shaft and bearings. Increasing the impeller is another option.
