Catalogue description records
This is a Neoprene piston cup kit (standard service) for the fluid end of FMC Bean reciprocating pumps. The piston cup is the flexible sealing element fitted to the piston; it seals against the cylinder liner bore as the piston reciprocates and is a routine wear item that directly affects volumetric efficiency. The "standard service" label denotes a general-duty cup configuration. It fits BEAN 435, W1122 and W1122BCD pumps and weighs about 0.53 lb.
