4inch oil cooled stainless steel submersible pump

 Description

4" stainless steel submersible pump has such advantages as good sealing performance,
corrosion resistance, quick heat elimination, deep-water pressure resistance,
long longevity 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 and
special maintenance is unnecessary. The motor inside is lubricated and cooled with
water. The general dividing depth of this pump can amount to 35 meters.
