Servicing Enerpac hydraulic pumps? The Enerpac DC9221101 Piston Ring 3P MPE is the genuine replacement part. The piston moves inside a bore under hydraulic pressure, either pumping oil or driving the tool. A scored or worn piston lets oil bypass and reduces output pressure.
When to replace the DC9221101
Replace it if the piston or its bore is scored, or if the tool loses pressure after the seals have been replaced.
