submersible motor / submersible pump / pump
zmscable 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. The casing and upper end are connected by bolt. 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 from graphite and thrusts lubricated & cooled by water ensured durable operation with heavy load.
The motors with advanced design offer good quality, long life service and easy maintenance.
