Sealing Head Assembly, HP, 1.125 Plunger, 60K | HJ-72110979
The HJ WATERJET HP Sealing Head Assembly, 1.125 Plunger, 60K (HJ-72110979) is a high-pressure intensifier topworks component engineered for large-frame waterjet systems operating up to 60,000 PSI (4,100 bar).
The HJ-72110979 HP Sealing Head Assembly is installed at the high-pressure end of the intensifier, where it performs three critical functions:
- Seals ultra-high-pressure water during compression
- Controls flow direction via inlet and discharge check valves
- Maintains pressure integrity for consistent cutting performance
It is a direct replacement for part 80072341, and is specifically designed for 1.125" plunger systems in high-horsepower applications (75–200 HP).
Key Benefits
- Restores Full Pressure Output – Critical for 75–200 HP systems
- Improves Flow Efficiency – Optimized internal flow path
- Reduces Internal Leakage – Maintains sealing integrity
- Handles High Duty Cycles – Built for continuous industrial use
- Faster Downtime Recovery – Replace vs rebuild entire head
