There are several types of couplings commonly used for pump shaft connections, including flexible couplings, rigid couplings, gear couplings, and fluid couplings. Flexible couplings are ideal for applications requiring misalignment compensation, while rigid couplings provide a solid connection for precise alignment. Gear couplings are suitable for heavy-duty applications with high torque, while fluid couplings use hydraulic fluid to transmit power and dampen vibrations.
