QJ Deep well submersible pump

QJ Series deep well submersible pump    

Introduction          

1. QJ series submersible motor deep well pump is an equipment mainly used for groundwater extraction, also widely used in field irrigation, drainage of factory enterprises and domestic water supply of  plateau mountainous area.

2. QJR series submersible hot water pump, adopt special material and structure, used for extraction of underground hot water.

3. The deel well submersible pump joins the pump body and motor into one.

3. With graphite bearing, it's very wear-resisting.

4. Aapplies new design theory,specical structure and advanced material, the efficiency has been improved 20% than traditional water pump.

5. Easy installation,safe and reliable operation, convenient maintainanc
