deep well irrigation water pumps 5hp

Introduction          

1. QJ series submersible motor deep well pump is an equipmet mainly used for groundwater extraction and 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. Submersible deep well pump joins pump body and motor into one.

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

5. Applies  new design theory and new design technique,its efficiency has been improved 20% than traditional water pump

6. Easy installation, safe and reliable operation, convenient maintainance.
