Dynamic Seal Backup 1-11610 for Waterjet Pump Sealing Parts

The Dynamic Seal Backup 1-11610 is an important supporting sealing component used in Waterjet Intensifier pump systems. Its main function is to provide structural support and anti-extrusion protection for dynamic seals operating under ultra-high-pressure conditions.
This backup ring works together with dynamic seals to prevent seal deformation, extrusion into clearance gaps, and premature seal failure during high-pressure reciprocating motion. It helps maintain correct seal geometry, improve sealing efficiency, and ensure stable operation of the hydraulic system.
A high-quality dynamic seal backup is essential for protecting primary seals, maintaining pressure stability, and extending service life of the intensifier system.

Is Dynamic Seal Backup 1-11610 a Wear Part?

Yes — the Dynamic Seal Backup 1-11610 is considered a wear part.
Although it does not directly seal fluid like primary seals, it is continuously subjected to high pressure, mechanical stress, and frictional forces. Over time, it may experience deformation, cracking, hardening, or edge wear.
If not replaced when damaged, it can lead to seal extrusion, hydraulic leakage, pressure loss, and damage to related sealing components.
Regular inspection and scheduled replacement are strongly recommended.
