Back Ring-Static | HJ-5100113 | High-Pressure Check Valve Backup Ring
The HJ-5100113 Backup Ring is a precision-engineered high-pressure sealing support component designed for BFT ultra-high-pressure waterjet pumps. Installed within the check valve assembly, the HJ-5100113 Backup Ring provides critical support to the sealing system by preventing seal extrusion under extreme operating pressures while maintaining proper alignment of internal valve components.
Manufactured from premium wear-resistant materials, the HJ-5100113 Backup Ring delivers exceptional durability, dimensional accuracy, and long service life in demanding industrial waterjet applications operating up to 4,000 bar (60,000 PSI).
The HJ-5100113 Backup Ring helps reduce internal wear, extend check valve life, minimize downtime, and maintain consistent pump efficiency.

Compatible Equipment
Suitable for numerous BFT pump platforms including:
- BFT ECOTRON
- BFT ECOTRON 38
- BFT SERVOTRON
- Additional compatible BFT high-pressure intensifier pumps using Part Number 5100113.
Function
The HJ-5100113 Backup Ring serves an important role inside the high-pressure check valve assembly by:
- Supporting high-pressure seals
- Preventing seal deformation
- Eliminating seal extrusion
- Maintaining valve stability
- Reducing component wear
- Improving sealing performance
- Extending maintenance intervals
- Increasing overall pump reliability
Without a properly functioning backup ring, seals may prematurely fail, resulting in leakage, pressure loss, reduced cutting performance, and costly downtime.
Benefits
✔ Precision Manufactured
✔ High Pressure Rated
✔ Long Service Life
✔ Excellent Wear Resistance
✔ Easy Installation
✔ Reduced Maintenance Costs

Maintenance Recommendation
During scheduled maintenance of the high-pressure check valve assembly, inspect the backup ring for:
- Wear
- Deformation
- Surface damage
- Cracking
- Compression set
Replacing the backup ring whenever the check valves are serviced helps maintain proper sealing performance and extends the life of adjacent components. Backup rings are commonly included alongside check valve service components in major maintenance kits.
