SN(SM) Series 3 - Phase Asynchronous water submersible motors are filled with water, chiefly used to directly drive deep well pumps in 6", 8", 10", 12" 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 latest design are made of best quality materials, thus the motor can operate under high axial thrust and longer motor run life can be guaranteed.
Application For lift underground water from wells or reservoirs For industrial water supply For mine drainage and farm irrigation
