pump pump shaft transmits power and supports impeller with various materials, such as 45 steel, forging and turning, etc.

The pump shaft of the pump is the key part of the pump.



In material selection:

- Pumps for transporting clean water and other non-corrosive media are generally made of 45 steel, which is subjected to quenching and tempering treatment. 45 steel has high strength and toughness, meeting the working requirements.

- Pumps for transporting weakly corrosive media such as salt solution, with the pump shaft made of 40Cr material and subjected to quenching and tempering treatment to enhance corrosion resistance.

- Corrosion-resistant pumps for transporting acidic and alkaline media with highly corrosive properties, the material of the pump shaft is generally 1Cr18Ni9, 1Cr18Ni9Ti, and other types of stainless steel, with excellent corrosion resistance.

Structurally, the common approach is to use a stepped shaft form to accommodate different installation conditions and load distributions. The shaft is also equipped with components such as bearings and axial seals, which work together to ensure the stability of the pump shaft's operation and prevent fluid leakage.Here are 60 key terms about the pump shaft of a water pump:
