Introduction to different specifications of coupling for pump fittings
Dec 25, 2018

As one type of pump fitting, a coupling refers to a mechanical part that is used to couple two shafts in different mechanisms and rotate them together to transmit torque. In high-speed and heavy-duty power transmissions, some couplings also have the function of damping and improving the dynamic performance of the shafting. The coupling consists of two halves, which are respectively coupled to the drive shaft and the driven shaft. Most of the general power machines are connected to the working machine by means of a coupling.


For example, in the structural composition of the horizontal centrifugal pump, the motor pump body and the motor are mainly connected by the pump fitting coupling. Different working conditions, the specifications of the coupling required by different customers are different. Among them, the pin coupling is a simple coupling, which is convenient to install and is used in a large pump for comparing motor power.


Another commonly used pump fitting coupling is mostly used for small water pumps, that is, claw couplings. This type of coupling is simple in structure, small in size, light in weight, inexpensive, and easy to install. There is also a kind of diaphragm coupling, which has the characteristics of simple structure, large transmission torque and high temperature resistance.www.pump-casting.com
