How to Maintain Submersible Sewage Pump?

Released on May. 11, 2018

In order to ensure the normal use and life of submersible sewage pumps, regular inspections and maintenance should be carried out:

1Replace the seal ring: After long-term use in the sewage medium, the gap between the impeller and the seal ring may increase, resulting in the decrease of the flow rate and efficiency of the water pump. Turn off the switch, lift the water pump, remove the bottom cover, and seal the lower ring , According to the actual size of the impeller ring with seal ring, the gap is generally about 0.5mm.

2 If the submersible sewage pump is not used for a long period of time, it should be cleaned and lifted up in a ventilated and dry place. Pay attention to antifreeze. If placed in water, run for at least 30 minutes every 15 days (cannot be dry milled) to check its function and adaptability.

3 Check the cable at least once a year, and replace it if it is damaged.

4 Inspect the motor insulation and fastening screws at least once a year. If the fastening screws are loose, tighten them again.

5 The submersible sewage pump has injected proper amount of engine oil before leaving the factory to lubricate the mechanical seal. The engine oil should be checked once a year. If water is found in the oil, it should be drained, the oil replaced, the gasket replaced, and the screw plug tightened. After three weeks, it must be re-examined. If the oil becomes emulsion again, the mechanical seal should be inspected and replaced if necessary.
