Mud Pump Pony Rod

We can offer a wide range of extension (pony) rods for triplex mud pumps that are made of high quality alloy steel (40Cr). After strict heat treatment of quenching and high temperature, the rods have the features of high intensity on surface and high tough inside. The surface is treated with galvanization or nitrogen for high intensity and low abrasion.



Mud Pump Pony Rod


Pony rod also called the intermediate rod, is an important part of the connection between the crosshead and the piston rod. It is the key component that connects the power end and the hydraulic end of the mud pump. One end is connected to the crosshead and the other end is connected to the piston rod by a clamp. Its outer circumference is filled with a packing box assembly. In the reciprocating motion, the outer circle of the intermediate tie rod and the sealing member in the packing box rub against each other. To ensure it’s wear resistance, the outer surface of the intermediate rod is hard chrome-plated.

The pony rod is made of premium quality, heat treated alloy steel. The surface is Chrome plated and polished to mirror-like finish. The rod is precisely made and treated with excellent abrasion and corrosion resistance. it is Forged of quality alloy steel, and made via thermal refining, high frequency and chroming with high mechanical strength, shock resistance.
