The main purpose of sewage pumps is to discharge sewage, but when it comes to the selection of sewage pumps, it is simple and simple. 

However, if the selection is incorrect, the motor will be burned and the purchased pump cannot be used, so the selection of sewage pumps is crucial.

So when selecting a sewage pump, the first thing we need to consider is what special circumstances will we encounter?

(1) Hair and convenience bags in the bath center;

(2) Convenient bags in hotels, hotels and kitchens;

(3) Woven bags, braided ropes, and plastic bags in the accumulated water pit.

(4) sanitary napkins and other fibers in septic tanks;

The above four situations are the most common problems we encounter. In such situations, we need to consider the problem of sewage pump 

blockage, so conventional sewage pumps are definitely not possible. Here we need to use a submersible sewage pump with cutting or tear-type 

submersible sewage pump. The WQK cut submersible sewage pump and AS tear-type submersible sewage pump produced by Shanghai Dingfei 

Pump Industry Co., Ltd. can effectively solve this problem. Customers are welcome to consult and purchase! !

The main models of sewage pumps will be discussed here. Mainly include QW, WQ, JYWQ, JPWQ, WQK/QG, AS/AV, GW, LW, ZW and other series of sewage pumps

Notes on use are as follows:

1. Check whether the cable is damaged or broken. If there is any damage, it must be replaced in time to avoid leakage; the cable cross-section should

 be matched with the current.

2. Before operation, use a megohmmeter to check the insulation resistance of the motor stator winding to the ground, and the minimum must not be

 less than 50 megohm.

3. When the sewage pump dives into the water, it should be lifted vertically, not allowed to be placed horizontally on the ground, and it should not be 

trapped in the sludge. When stopping use, the electric pump should be lifted and cleaned, placed in drying, and pay attention to anti-freezing.

4. When the power supply exceeds ±10% of the rated voltage, the electric pump shall not be started.

5. To ensure safety of use, the grounding wire in the four-core cable must be reliably grounded to prevent electric shock accidents.

6. It is prohibited to use the cable as a mounting rope.

7. Check the direction of the rotor running, and the rotation should be clockwise from top to bottom.

8. Outdoor switches or wiring terminals should have rainproof and moisture-proof measures. Do not touch the switch when wet hands or barefoot to 

prevent electric shock.

9. When moving the sewage pump, the power supply must be cut off. People must not contact the power supply when the electric pump is running to 

prevent leakage and personal accidents.
