Catalogue description records
This is a 2-1/4 inch SuperGold piston cup for abrasive service, 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 Aplex SC-45L pump, and the "abrasive service" designation in the name indicates it is intended for pumping abrasive fluids.
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.
