HP Cylinder Liner, .875 Plunger, 60K | HJ-20497767
The HJ WATERJET HP Cylinder Liner, .875 Plunger, 60K (HJ-20497767) is a precision-machined liner designed for high-pressure waterjet intensifier pumps operating up to 60,000 PSI.
The HJ-20497767 HP Cylinder Liner is installed inside the high-pressure cylinder assembly, where it provides a hardened, wear-resistant surface for the reciprocating plunger. It plays a critical role in maintaining sealing integrity, reducing friction, and extending the life of the intensifier system.
Engineered and designed as a direct cylinder liner replacement for multiple part numbers that are now obsolete, making it a standard upgrade component across many KMT-style systems.
Key Benefits
- Extends Pump Life – Protects cylinder housing from wear
- Improves Seal Performance – Provides smooth sealing surface
- Maintains Pressure Stability – Reduces leakage and pressure loss
- Reduces Maintenance Costs – Replace liner instead of full cylinder
- Improves Efficiency – Minimizes friction and wear on plunger

Maintenance Recommendation
For maximum intensifier performance, inspect the HJ-20497767 HP Cylinder Liner whenever replacing:
- High-pressure seals
- Ceramic plungers
- Check valve components
- HP cylinder assemblies
Replacing a worn liner during routine maintenance helps prevent premature seal failure, pressure loss, and accelerated plunger wear.
