Catalogue description records
This is a 5-inch piston assembly, an aftermarket replacement part for triplex and duplex mud pumps. As a complete piston — the rigid body together with its sealing rubber — it reciprocates inside the cylinder liner bore to move the drilling fluid on every stroke. The 5-inch size corresponds to the liner bore it is matched to; the model and part references are listed for identification only.
A piston assembly is the complete piston — body and sealing rubber — that reciprocates in the liner to move the pumped fluid.
Catalogue question records
Original catalogue questions are retained. Fitment and availability need technical review.
- What is a piston assembly and what does it do?
- A piston assembly is the complete piston — body plus sealing rubber — that reciprocates inside the cylinder liner to move the pumped fluid. It is a routine wear item in the fluid end of a mud pump.
- What size is this piston assembly?
- This is the 5-inch (5寸) size. The piston size is matched to the liner bore it works in, so it should be paired with a 5-inch cylinder liner.
