Product ID: 05144712 – Cylinder Liner / High-Pressure Cylinder Liner

Description:
This component is a high-pressure cylinder liner, specifically a plastic liner designed for use in the high-pressure cylinder assembly of waterjet intensifier pumps . It is a precision-molded, thin-walled cylindrical component that serves as a wear-resistant lining within the cylinder bore. The liner provides a smooth, low-friction surface for the reciprocating ceramic plunger, protecting the more expensive cylinder body from wear and extending the overall service life of the high-pressure assembly .

This cylinder liner is designed for use with 0.875 inch (7/8") diameter plungers in 60,000 PSI (approximately 4,137 bar) intensifier pumps . This part number is now obsolete but can be replaced by part number 20497767 .

Alternative or cross-reference part numbers include: 10110419, 05132246, 05109624, 05121777, 80080021, 20481574, and 20418805 . The component has an approximate weight of 0.114 lbs (0.06 kg) .

Applications:

• Used as a protective liner within the high-pressure cylinder of waterjet intensifier pumps .

• Installed between the cylinder bore and the reciprocating ceramic plunger to provide a smooth, wear-resistant contact surface .

• Suitable for ultra-high pressure waterjet systems operating at 60,000 PSI (approximately 4,137 bar) .

• Compatible with 0.875 inch (7/8") plunger intensifier pumps (SL-IV, SL-V, Classic, and OEM series).

Features:

• Constructed from wear-resistant plastic material, providing a low-friction surface for the reciprocating ceramic plunger .

• Precision-molded to exact dimensional specifications for proper fit within the high-pressure cylinder bore .

• Functions as a sacrificial component; the liner is designed to wear over time while protecting the more expensive cylinder body from damage .

• Provides precise guidance for the ceramic plunger during high-frequency reciprocating motion .

• Lightweight design (approximately 0.114 lbs / 0.06 kg) for easy handling during replacement .

• Engineered for 60,000 PSI continuous operation .

Maintenance:

• Critical Wear Component: The cylinder liner is a high-wear consumable part. It should be inspected regularly and replaced as part of scheduled preventive maintenance .

• Inspection: During intensifier pump overhaul, inspect the cylinder liner for signs of wear, scoring, cracking, or deformation. Also inspect for debris buildup or wear patterns that could affect plunger performance.

• Replacement Criteria: Replace the cylinder liner if any visible wear, scoring, cracking, or deformation is detected. A worn liner can cause misalignment or increased friction on the ceramic plunger, leading to plunger damage or seal failure .

• Simultaneous Inspection: When replacing the cylinder liner, inspect the ceramic plunger and cylinder bore for signs of wear or damage. Replace components as necessary.

• Full Depressurization: Always fully depressurize the waterjet system and follow lockout/tagout procedures before removing the high-pressure cylinder or replacing the cylinder liner.

• Proper Handling: Handle the plastic liner with care to avoid scratching or deforming the precision surfaces during installation.

• Compatibility Verification: This part number (05144712) is obsolete. Replacement is part number 20497767 . Ensure compatibility with 0.875 inch plungers and 60,000 PSI pressure rating.

• Plunger Lubrication: Before inserting the plunger into the new liner, apply manufacturer-recommended assembly lubricant to the plunger surface to prevent dry startup and reduce initial friction.
