Product ID: 80080021 – HP Cylinder Liner (Discontinued)

Description:
This component is a high-pressure (HP) 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 and is compatible with 60,000 PSI (approximately 4,137 bar) intensifier pumps . It is manufactured from plastic material with a product weight of approximately 0.06 kg to 0.136 lbs depending on variant and manufacturer specification .

IMPORTANT DISCONTINUATION NOTICE:
This part number (80080021) has been discontinued and is now obsolete . The manufacturer has superseded this component. Replacement liner part numbers include SF20497767 and 20497767 . These replacement numbers consolidate and replace multiple obsolete part numbers including 10110419, 05132246, 05109624, 05121777, 05144712, 80080021, 20481574, and 20418805 .

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 including KMT style pumps 

• Specifically listed as component #11 in SL-IV series intensifier pump parts diagrams 

Features:

• Wear-Resistant Plastic Construction: Manufactured from durable plastic material, providing a low-friction surface for the reciprocating ceramic plunger 

• Precision-Molded: Manufactured to exact dimensional specifications for proper fit within the high-pressure cylinder bore 

• Sacrificial Protection: Functions as a consumable component; the liner is designed to wear over time while protecting the more expensive cylinder body from damage 

• Precise Plunger Guidance: Provides accurate guidance for the ceramic plunger during high-frequency reciprocating motion 

• 60,000 PSI Rating: Engineered for continuous operation at ultra-high pressure 

• Compatibility: Designed for all 60K KMT style pumps using 0.88 plungers 

Maintenance:

• Critical Discontinuation Notice: This part (80080021) is discontinued. When replacement is required, use superseding part numbers SF20497767 or 20497767 

• 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 unusual 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

• 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

• Cross-Reference Information: This part number is listed as component #11 in complete intensifier pump parts diagrams, appearing alongside other components including the high-pressure cylinder (20460891), plunger assembly (05039771), seal assembly (20422243), hydraulic cartridge assembly (80086622), and O-rings (10075000, 10074904)
