Specification :

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.
