The function of a pump shaft is to transmit the drive power to the displacement elements of positive rotary displacement or the centrifugal pumps
impellers. Impellers are usually mounted onto pump shafts which are often made of stainless steel and designed to support the rotating impeller. A pump shaft features a careful design with high precision sizing to reduce pump vibration, pump shaft breakage and shorter bearing life. The pump shaft is usually protected by a pump sleeve which is located below the sealing arrangement. It also used to fix the impeller on the shaft correctly and is threaded or slid onto the shaft. The pump shaft also has bearings
that support and hold it in place are designed to withstand the force of the rotating impeller mounted on the shaft. Pump shafts are used in various types of pumps including impulse pumps, positive displacement pumps, velocity pumps, valveless pumps, gravity pumps and steam pumps.
