Catalogue description records
The Piston Cup Holder for FMC Bean L1122/W1122/L1622 is a fluid-end piston component that carries and locates the piston cup seal against the cylinder liner bore as the piston reciprocates. It fits FMC Bean models L1122, L1122D, L1622, L1622HV and W1122. This is an aftermarket replacement cross-referenced to FMC Bean part A91653.
A piston cup is the flexible sealing element fitted to the piston in the fluid end. It maintains the seal against the cylinder liner bore as the piston reciprocates, so wear here directly affects volumetric efficiency.
