Couplings essentially connect two drive elements (usually shafts) to allow rotary motion and torque to be transferred between them. This allows the motion from the pumps driver, such as an electric motor, to be transferred to the pump itself. Secondary functions of couplings can include accommodating misalignment between shafts, controlling the transmission of axial thrust and vibration between components of a pumping system, and maintain shaft alignment. Rigid or flexible couplings may be used, depending on the requirements of the application. The choice of coupling can have implications on pump efficiency, reliability and maintenance requirements.
