Product Name: Backup Sleeve (Part No. 20458161)

Description:
This component is a backup sleeve, a rigid annular support component specifically designed for the high-pressure seal assembly within the intensifier pump of a waterjet cutting system . Its primary function is to provide structural support to the high-pressure dynamic seals, preventing them from extruding or collapsing under the extreme pressure of the waterjet cutting process . By maintaining the integrity of the seal stack, the backup sleeve ensures a leak-tight seal and consistent pressure delivery to the cutting head .

The backup sleeve is a standard component in the intensifier pump assembly, typically installed between the hydraulic cylinder components and the high-pressure cylinder .

Applications:

Serves as a rigid mechanical support for the high-pressure dynamic seal stack within the waterjet intensifier pump .
Maintains the structural integrity of the seal assembly under extreme pressure cycles (typically 60,000 PSI / 4,137 bar) .
Compatible with major waterjet systems, including KMT, AccuStream, and others .

Features:

Rigid Support: Constructed from high-strength metal or durable plastic to provide a non-deformable backing for the elastomeric high-pressure seals .
Critical Component: Essential for preventing seal extrusion and maintaining system pressure.
Semi-Wear Part: While more durable than the seals themselves, this component can become worn or damaged over time and requires periodic inspection .

Maintenance:

Regular Inspection: It is important to regularly inspect the backup sleeve for signs of wear, deformation, or damage .
Replacement Criteria: Replace the backup sleeve immediately if it shows signs of cracking, permanent deformation, or wear, as a damaged sleeve will compromise the seal stack and lead to high-pressure leaks and pressure loss .
Systematic Replacement: It is standard practice to replace the backup sleeve whenever the high-pressure seal assembly is being rebuilt to ensure optimal system performance .
