Backup Ring 1-11680-114 for Waterjet Pump Parts Supplier

The Backup Ring 1-11680-114 is a critical sealing support component used in Waterjet Intensifier pump systems. Its main function is to support O-rings and dynamic seals under high-pressure conditions, preventing seal extrusion, deformation, and premature failure during operation.
This backup ring works together with sealing elements in hydraulic and ultra-high-pressure systems to maintain stable sealing geometry and improve overall sealing performance. It helps protect primary seals from excessive pressure load, extending the service life of both seals and related pump components.
A high-quality backup ring is essential for maintaining pressure stability, preventing leakage, and ensuring reliable long-term operation of the intensifier system.

Is Backup Ring 1-11680-114 a Wear Part?

Yes — the Backup Ring 1-11680-114 is considered a wear part.
Although it is more durable than soft sealing materials, it continuously operates under extreme pressure, friction, thermal cycling, and mechanical stress. Over time, it may wear, deform, crack, or lose its support capability.
If not replaced when worn, it can lead to seal extrusion, hydraulic leakage, pressure instability, and premature seal failure.
Regular inspection and scheduled replacement are strongly recommended.
