Piston Rod and Extension Rod:

Piston rods are forged by high quality alloy steel. The machinery performance of products is improved after heating treatment, phosphoirzation and zincification. Piston rod and extension rod are jointed by piston clamp, that allows quick installation or disassembly.

The big end of the piston rod is connected with the power end of the mud pump by the clamp to the extension rod; the small end is installed with the piston which moves forth and back in a direction in the cylinder liner to create the pressure.
