150QJ or 6″ three phase submersible borehole pump

This series of submersible pump 3 phase can fit in boreholes with 6 inch diameter. 150 here means 150 mm, which is close to 6 inches. This series is the smallest among our 3 phase submersible water pumps. They have simple construction, since they insist of only a simple inlet, impellers, motor and discharge bowl, etc. Sometimes we use centrifugal impeller, but other times we use mixed flow impeller, depending on the need of clients. When the 3 phase submersible water pump runs, water will flow in through inlet and pass by the impellers until it moves to the outlet. The discharge bowl of the pump and the guide vane of the impellers will help to send water out of the pump.

The two different constructions both have their advantages and disadvantages.
