Catalogue description records
This is a piston cup with a 2.75 inch outside diameter in a hemisphere style, made of neoprene and cotton. It is the flexible sealing element fitted to the piston in the fluid end of a reciprocating pump, sealing against the cylinder liner bore as the piston reciprocates, which makes it a routine wear part. It is sized for the FMC Bean R660 pump.
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.
