Backup Ring 1-11680-244 for Waterjet Pump Sealing Support Parts

The Backup Ring 1-11680-244 is an important sealing support component used in Waterjet Intensifier pump systems. Its main function is to provide structural support for O-rings and dynamic seals, preventing seal extrusion and deformation under ultra-high-pressure operating conditions.
This backup ring works together with sealing elements to maintain proper seal shape, improve pressure resistance, and extend the service life of the sealing system. It is especially important in high-pressure hydraulic and water sealing applications where extreme pressure and reciprocating movement are present.
A high-quality backup ring is essential for maintaining sealing reliability, preventing leakage, and protecting critical pump components.

Is Backup Ring 1-11680-244 a Wear Part?

Yes — the Backup Ring 1-11680-244 is considered a wear part.
Although it is more durable than soft seals, it continuously operates under extreme pressure, friction, mechanical stress, and thermal cycling. Over time, it may deform, crack, wear, or lose its support capability.
If not replaced when worn, it can lead to seal extrusion, leakage, pressure instability, and premature failure of the sealing system.
Regular inspection and scheduled replacement are strongly recommended.
