This cylinder cover is an aftermarket replacement part for triplex and duplex mud pumps. A cylinder cover (liner cover) retains and seals the cylinder liner in the fluid end, holding it in place and closing the bore against the pumped fluid. The original Chinese designation is 缸盖 (cylinder cover). Any model or part numbers shown are used only for identification and do not imply original-equipment manufacture.
A cylinder cover closes the outer end of the fluid-end cylinder, retaining pressure and providing access for liner and piston service.
