Application scope:
WQ series submersible sewage pump has reliable performance and perfect quality. It can be used widely. This series pump adopts some know-how technology, its structure which can resist tear and clog can guarantee effectively that the solid particle (φ 50mm- 125mm) and fiber such as cotton, weed can pass smoothly.
WQ series pump can be used on many application such as mine, municipal engineering, hospital, hotel, village and marsh gas tank to pump civil sewage and industrical pollution water. It is also applied to oil extraction and irrigation. Operating range:
1. Maximal temperature: 40 °
2. pH: 5-9.

Operation instruction:
Pay attention to installation:
Before operating pump, a qualified electrician should check pump system. Be sure to make some electrical equipment protection measures as follow:
1. Before operating pump, a 0-500V megohmmeter should be used to measure resistance of the motor to the ground. Minimum resistance is 1 megohm.
2. Power voltage deviation can not exceed ± 10% of the rated voltage which is showed on the nameplate.
3. Check the motor rotation. Before operating the pump, start the pump on the ground, check the rotation is the same with the rotation marked on the pump body. If not, change two of them.
4. The pump should be controlled by a special panel. As pump with many protection device, like leakage monitor, temperature sensor, and so on. These device can protect pump from damage and prolong the pump life.
