Pump Impeller

Description

The impeller is a crucial part of a centrifugal pump that converts the energy from the motor into fluid movement by propelling the fluid away from the center of rotation. As the fluid is accelerated outwards, its velocity transforms into pressure when it is constrained within the pump casing. Impellers typically have a short cylindrical shape with an open inlet referred to as the eye, which allows the fluid to enter. They also consist of vanes that push the fluid in a radial direction and a bore that can be splined, keyed, or threaded to accommodate a drive-shaft.

The rotor, often referred to as the impeller, is commonly made of cast material. One cost-effective method is to cast the radial impeller directly onto the support structure. This support structure is then powered by a gearbox connected to an electric motor, combustion engine, or steam-driven turbine. In cases where both the spindle and impeller are mounted using bolts, they are collectively referred to as the rotor.
