The coupling has a close relationship with the centrifugal pump. The coupling connects the shaft of the centrifugal pump with the shaft of the prime mover. It has the pump and prime mover as a whole. When the prime mover rotates, the centrifugal pump is also at the same time. The role of rotating and transmitting torque.
Flange couplingIt is a fixed coupling with simple structure, accurate centering, good rigidity, and can transmit relatively large torque.However, it is required to be precise during installation and cannot mitigate the impact load of the pump. It is generally used on centrifugal pumps with low vibration, low speed and small impact load.
