Description
The piston ring is the rubber seal on the plunger. If that seal is worn out, you can pump all day but won’t build pressure. This Busch piston ring does the same crucial job inside your industrial pump.
Inside a Busch Mink pump, a piston moves back and forth very fast. This motion creates the vacuum. The piston ring sits in a groove on the piston. Its job is to press snugly against the cylinder wall as the piston moves.
This tight seal is what makes the pump work. It keeps the vacuum pressure from leaking past the piston. A good seal means strong, reliable suction. A worn ring means weak vacuum power, longer job times, and wasted energy.
Replacing a worn piston ring with this Busch part is a key repair. It brings your pump’s performance back to its original specifications. You’ll notice the difference in power and efficiency.
Made for durability, this OEM ring guarantees the perfect fit and material quality needed for long-lasting performance in demanding conditions.
