XBSY Centrifugal Sand Pump

Product details

The main function of the Centrifugal Sand Pump Shaft is to transmit power and support the impeller to keep it in normal operation. One end is connected to the motor shaft through a coupling, and the other end supports the impeller for rotating motion. The shaft is equipped with bearings, axial seals and other parts.

Pump Shaft Material and Structure

Because the pump shaft is used to transmit power and rotate at high speed, in pumps that transport clean water and other non-corrosive media, they are generally made of 45 steel and are quenched and tempered. In pumps that transport weakly corrosive media such as salt solutions, the pump shaft material is 40Cr and is quenched and tempered. 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 centrifugal 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.
