When replacing the pump sliding ring, it is important to keep the internal circulation at a proper value. This should be carried out periodically. The larger the drive power, the greater the energy saving effects will be. Also, if the pump operation is intermittent, energy saving effects can be expected by adding fluid couplings between the drive and the pump.

Over load (Overcurrent) occurs.
Excessive water leakage from stuffing box
Electric motor does not work well with noise.
Water comes out at first, but it doesn't come out soon.
