The mud pump piston is one of the main parts of the fluid end system of the mud pump, and also one of the vulnerable parts in drilling work. The discharge pressure of mud pump is produced through the reciprocating rectilinear motion of the piston assembly in the piston. The piston assembly is composed of a piston core, rubber, spring, pressing plate, etc..

Mud pump piston and cylinder liner constitute a pair of dynamic sealing and sealing components are assembled on the piston (some mud pump pistons don’t have cylinder liner and are directly linked to the inner wall of the cylinder body). The reciprocating motion of the piston alternately changes the volume of the working chamber and the pump suck and discharge the liquid through the valve.

Therefore, the mud pump piston is required to have the following properties:
(1) Good sealing;
(2) Sufficient strength and stiffness;
(3) The piston body should be firmly positioned and connected to the piston rod, the piston ring, and other parts.

We are specialized in producing mud pump pistons, and our product, the F1300 triplex piston mud pump, has advanced structure, small volume, reliable operation and is easy to maintain. The cylinders are made of alloy steel forgings and the three cylinders of each pump are interchangeable. The suction and exhaust valves of the F1300 and the F1600 can be used interchangeably, too. In order to improve their corrosion resistance, the cylinder surface is treated with chemical nickel-plating, and the straight-through cylinder valve structure is designed to reduce the volume of the hydraulic cylinder and improve the volume efficiency.
