Catalogue description records
This is a 2-1/4 inch SuperGold piston cup for abrasive service in a preformed style, the flexible sealing element fitted to the piston in the fluid end of a reciprocating pump. It seals against the cylinder liner bore as the piston reciprocates and is a routine wear part. It is sized for FMC Bean L1118SC and L1618SC pumps, and the "abrasive service" designation in the name indicates it is intended for pumping abrasive fluids.
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.
