We have two kinds of shaft sleeve for major brand centrifugal pump, 316 stainless steel and 416ss ceramic coating, the later with ceramic coating provides a good wear-resistance to ensure a longer service life.
Mission Pump Shaft 20612-02-33
The main function of the Mission Pump Shaft is to transmit power and support the impeller to keep it in normal operation. One end connects to the motor shaft through a coupling, and the other end supports the impeller for rotating motion. The shaft features bearings, axial seals, and other parts.
Pump Shaft Material and Structure
Because the pump shaft transmits power and rotates at high speed, in pumps that transport clean water and other non-corrosive media, we generally make them from 45 steel and quench and temper them. In pumps that transport weakly corrosive media such as salt solutions, the pump shaft material becomes 40Cr, and we quench and temper it. In terms of corrosion resistance, pumps used to transport strong corrosive media such as acid and alkali, the shaft material is generally stainless steel such as Cr18N, Cr18Ni9Ti.
The mission pump shaft is a stepped shaft part, generally as a whole, but in anti-corrosion pumps, due to the high price of stainless steel, sometimes combined parts are used, the part contacting the medium is made of stainless steel, and the bearing and coupling are installed. Use high-quality carbon cable structural steel, bearing connection between stainless steel and carbon steel, and pin reinforcement for interference fit.
