Piston Cup Kit Abrasive Service HSN for FMC Bean L1622

The Piston Cup Kit Abrasive Service HSN for FMC Bean L1622 supplies the flexible piston cup sealing element for the fluid end of reciprocating pumps. The cup seals against the cylinder liner bore as the piston reciprocates and is a routine wear part. As the name indicates, it is intended for abrasive-service duty, where the pumped fluid carries solids that accelerate seal wear. It fits FMC Bean models L1622 and L1622HV, weighs about 0.51 lb, and is an aftermarket replacement cross-referenced to FMC Bean part P508620.
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.
