Today, let's take a look together and see when the efficient and non clogging sewage pump needs to be replaced with oil, which is very helpful for everyone. In general, before leaving the factory, the manufacturer has already injected it.

1. The efficient and non clogging sewage pump has been injected with an appropriate amount of engine oil before leaving the factory to lubricate the mechanical seal, and this engine oil should be checked once a year.

2. If water is found in the pump oil after reuse, it should be drained, replaced with the oil, the sealing gasket, and the screw plug tightened. After three weeks, it is necessary to recheck. If the oil returns to emulsion, the mechanical seal should be inspected and replaced if necessary.
