The function and principle of the drive coupling for a high-flow, high-head multistage pump

The drive coupling of a high-flow, high-head multi-stage pump is a key component connecting the motor and the pump. Its main function is to smoothly transmit the rotating power of the motor to the pump through elastic elements and friction surfaces, and to absorb any deviations and stresses that may occur during equipment operation. Its working principle is based on elastic and frictional characteristics, achieving efficient and reliable transmission through a series of complex structures and devices. During use, attention should be paid to maintaining and checking the status of the drive coupling to ensure its normal operation and the stable operation of the entire system.
