4SD water cooled stainless submersible motor pump for deep well

The stator is externally welded and internally lined with stainless steel, and is also filled and sealed with epoxy resin. Then the products have such features as good sealing performance, corrosion resistance, quick heat
elimination, deep-water pressure resistance, long life span and low cost.

The rotor takes the squirrel-cage type. The tank is molded with high quality aluminum ingot or circumferentially welded with copper stripe and
copper ends, so that it is hard to distort or fracture and has good conductibility and high efficiency. The sheet steel has gone through chemical treatments and
won't rot. In addition,footstep bearing is adopted that larger axial load can be
borne.

The motor inside is lubricated and cooled with water,because water won't bring pollution and special maintenance is unnecessary. The general dividing depth of this pump can amount to 350 meters, which solves the internal
problem of deep-water activities and scientific research.
