There is no filter in the pump，Thanks to the filter cover, it is easy to filter fine particles and impurities, the water is hardly clogged, so that the filtration is more efficient, the service life is longer and the maintenance time is reduced. Under no circumstances should the water pump work without water (dry running). This may damage the pump shafts. Before starting, the pump body must be filled with clean water. The water pump should not be placed directly in the sludge at the bottom, and the position should be raised, otherwise the service life will be shortened. If the water environment is turbid, it is recommended to clean the filter cover and internal devices every 2 weeks. Normally, it should be cleaned once every 4 weeks.
