Catalogue description records
This is a 1-5/8 inch nitrile piston cup, the flexible sealing element that fits onto the piston in the fluid end of a reciprocating pump. As the piston reciprocates it maintains the seal against the cylinder liner bore, so this is a routine wear part. It is sized for FMC Bean R10 and R2020 pumps.
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.
