The most commonly used submersible is QW submersible sewage pump, and the most common dry sewage pumps are W horizontal sewage pump and WL vertical sewage pump. However, since the medium transported by the sewage pump contains impurities such as mud and sand, long-term use can easily cause blockage of the sewage pump. Therefore, it is necessary to prevent the sewage pump from blocking to improve its overall working efficiency.

The utility model is a sewage pump with a filtering function. The filter cartridge can be sleeved on the sewage pump water inlet end through the setting of the fixing ring, which can effectively prevent the accumulation of debris in the flow channel of the sewage pump, and the water entering the sewage pump water inlet end can be filtered to avoid damage to the sewage pump. Moreover, through the waterproof motor arranged at the bottom of the mounting plate, the waterproof motor can drive the debris removal brush plates at both ends of the rotating plate to brush away the impurities adsorbed on the outer wall of the filter cartridge, so that the filter screen has a better protective filtering effect on the waterproof motor, so that the motor will not run idle, and the motor can be avoided from being damaged.
