Catalogue description records
This is a 1-5/8 inch abrasive-service HSN piston cup for FMC Bean piston pumps. It is the flexible sealing element fitted to the piston in the fluid end, maintaining the seal against the cylinder liner bore as the piston reciprocates. The "abrasive service" designation in the name indicates it is intended for duty handling abrasive fluids, and "HSN" is the seal-compound designation given in the product name. It fits the FMC Bean A0413, E0413, and L0413 models. Supplied as an aftermarket replacement that can replace FMC Bean part number 3267349.
