Piston Cup Kit Abrasive Service Supergold Hemisphere Style Cup for FMC Bean L0618HV/L0618COMP/L0918HDHV — Piston Cup aftermarket replacement part

This is a SuperGold hemisphere-style piston cup kit (abrasive service) for the fluid end of FMC Bean reciprocating pumps. The piston cup is the flexible sealing element fitted to the piston; it rides against the cylinder liner bore as the piston reciprocates, so it is a routine wear item whose condition directly affects volumetric efficiency. The "abrasive service" designation in the name indicates the cup is intended for duty handling abrasive or solids-laden fluids. It fits FMC Bean L0618COMP and L0618HV pumps and weighs about 0.58 lb.

What it is
