The use of sewage lift pump has solved the sewage discharge problem in many places far away from the drainage riser and with poor drainage conditions. Sewage lift pump is increasingly favored by people, and how to choose sewage lift pump has become a new problem. The basic parameters of sewage lift pump selection are caliber, flow, lift, power, voltage, liquid and so on.

1. Select the appropriate sewage pump according to the discharge flow and transportation lift.

2. Reasonable selection of sewage pump according to the usage. For example, to transport sewage with high sediment concentration, choose sewage pump with good wear resistance; If it is used to transport sewage or dirt, the maximum particle size of sewage pump should be considered; If transporting corrosion-resistant medium, corrosion-resistant pump should be considered; If the sewage contains fecal impurities, it is necessary to consider choosing a sewage pump with cutting function.

3. On the premise of saving energy and meeting the use requirements, select an efficient sewage pump, and the parameters of the selected sewage pump run within the range of 0.7- 1.2 times of the rated flow.

4. Choose single-phase or three-phase sewage pump according to different power sources.

5. According to the price, quality condition, operation cost and convenience of installation and maintenance of sewage pump, select the appropriate pump comprehensively.

6. Check whether the sewage pump has reliable grounding device and safety protection device, so as not to affect the safe use of the sewage pump.

Pay attention to the appearance of the pump when selecting, and check whether the pump body and pump cover are damaged, whether the cable is damaged, whether the corroded bolts on the pump surface are loose, and whether there are traces of electric leakage and water leakage.
