A pump impeller is the rotating part of a centrifugal pump that transfers the motor energy which powers the pump. This is the pump that pumps
to the fluid that is being pumped up when the fluid is accelerating outwards from the rotational center. The impeller consists of a short cylinder that has an open inlet, for fluid inflow and vanes that radially push the fluid. It also has a bore that can be splined, threaded or keyed which accepts the drive shaft. The pump casing confines the fluid's outward movement, which in turn transfers the rotational velocity into pressure. The types of pump impellers are open impellers, semi-open impellers and closed impellers. They are used broadly in various application fields including in centrifugal compressors, agitated tanks, water jets, washing machines, medical devices, fire fighting rank badge and air pumps. Mechanical circulatory devices or heart pumps use a design of a pump that has a continuous axial flow impeller. Impellers are also used in water jets for powering high-speed boats.
