What is the shaft?

To the displacement elements of rotary positive displacement pumps or the impellers of centrifugal pumps, the pump shaft transmits the drive torque. The central component of a centrifugal pump rotor is the pump shaft. It carries the impellers, the shaft sleeves, the bearings, and the coupling as well as other components that are part of the rotor.

What are the factors that affect the shaft’s ability?

  • The size of the shaft. When it comes to overall stiffness, the distance between the bearings is more important than the shaft’s diameter.
  • The Surface finish and stress concentration points of the shaft are also other determining points for the level of functionality of the pump.
  • Shafts fail more quickly which allow liquid to reach the points of stress concentration than one that remains dry. So this is also a factor that affects the shaft’s ability.
