Piston Cup 3.0 OD Pro Gold
This is a 3.0 OD Pro Gold piston cup, the flexible sealing element fitted to the piston in the fluid end of a reciprocating pump. As the piston reciprocates it maintains the seal against the cylinder liner bore, making it a routine wear part. It is sized for the FMC Bean M1324 pump.
What it is
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.
