Product Description
The HJ WATERJET HP Cylinder Liner, .875 Plunger, 60K (HJ-20497767) is a precision-machined component designed for high-pressure waterjet intensifier pumps operating up to 60,000 PSI.
This 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
Compatible Pumps
The HJ-20497767 cylinder liner is compatible with:
- NeoLine Series
- SL-IV Series (15 HP – 60 HP)
- SL-IV Plus Series
- SL-V Series
- SL-VI Series
These systems utilize .875 plunger intensifier assemblies, where the liner acts as the primary wear surface.
Applications
The HJ-20497767 liner is widely used in:
- Waterjet cutting systems (metal, composites, plastics)
- Automotive manufacturing
- Aerospace fabrication
- Stone and glass cutting
- Industrial production environments
