The centrifugal pump impeller is most typically supported on its own shaft and bearings and driven by an electric motor, and less often by an engine or a turbine.The function of the bearings in a centrifugal pump is to keep the shaft or rotor in correct alignment with the stationary Centrifugal Pump Bearings parts under the action of radial and transverse (axial) loads (see Fig. 1). Bearings that give radial positioning to the rotor are known as line bearings, and those that locate the rotor axially are called thrust bearings.

Centrifugal pump This example shows the bearing selection process applied to an application case in which modification is required to a centrifugal pump. The pump manufacturer wants to improve the SKF tkba 40 Bearing efficiency of an existing centrifugal process pump by modifying the impeller.centrifugal pump operation principles, pump bearing details including bearing life, bearing lubrication, etc. Part II includes: application of ball and roller bearings in detail, comparative viscosity classifications, unit conversions, and references.
