stainless steel submersible pump

QN/QM Series three phase asynchronours water submersible motors are filled with water,chiefly used to directly drive deep well pumps in 6inch,8inch,10inch,12inch casings in order to lift under ground water for city and industrial water supply as well as for mine drainage and farm irrigation.

These motors are perfect in design and simple in construction with the features of low-noise,energy efficient excellent performance reliability and easy maintenance.

Bearings of lastest design are made of best quality materials,thus the motor can operate under high axial thrust and longer motor run life can be guaranteed.

1.     technical data

1.1  Rated Voltage:380V/50HZ,three phase A.C. synchronous speed:3000R.P.M.

1.2  Motor operates continuously

1.3  Motor’s rated output can be guaranteed when rated voltage deviation does not exceed ±5% and rated frequency does not exceed ±1%.

2.     Working Conditions

2.1  The motor should be completely submerged in water, It’s highest position should be below the moving water level.But should not exceed 70m.It’s lowest position to well bottom should be no less than 5 meters.

2.2  Well water should be generally clean,containing sand no greater than 0.01%(by weight).

2.3  Well water temperature should not exceed +30°C

2.4  Well water contains no chemical corrosives,PH value with in 6.5-8.5

2.5  Motor should be operated in vertical. Water passing the motor’s surface is more than 0.5m/s. in order for heat—dissipating.
