Mud Pump Pull Rod

The pull rod is an important part of the connection between the crosshead and the piston or plunger. It is a key component connecting the power end and liquid end of the mud pump. 

One end is connected to the crosshead and the other end is connected to the piston or plunger. Its periphery is equipped with a stuffing box assembly. During the reciprocating movement, the outer circular seals of the intermediate tie rods rub against each other. In order to ensure its wear resistance, the outer surface of the middle rod is sprayed with alloy.
