2010 new type water submersible motor

water submersible motor HEM Water Submersible motor is water filling 3 phase induction motor which is designed for driving water submersible pump and gives reliable quality. The motor is water insulated design. All conductors of squirrel-cage of the rotor are made of pure copper bars. And the stator winding is using water-proof wires. The thrust bearing is made fromspecial plastic and thrusts lubricated & cooled by water ensured durable operation with heavy load. Themotors with advanced design offer good quality, long life service and easy maintenance.
