NM rubber coupling, also called claw coupling. The structure is similar to the elastic plum blossom coupling, using specially designed synthetic rubber, with two similar bodies of cast iron material, rubber coupling NM series. Mainly two cast iron (FC25 material) bodies plus rubber coupling, rubber The NM series coupling is made of (FC25) cast iron, with rubber in the middle as a buffer pad. The coupling is a connecting part between the pump and the motor, and is often used in general machinery.
