Product Name: Backup Sleeve, 15 GPM, 60k (Part No. 100018-3)

Description:
This component is a precision-machined backup sleeve specifically designed for high-pressure sealing stacks in 60,000 PSI (approximately 4,137 bar), 15 GPM waterjet intensifier pumps. It serves as a critical anti-extrusion component, installed adjacent to O-rings or dynamic seals within the cylinder bore or plunger gland. Manufactured from rigid, wear-resistant materials such as stainless steel or hardened alloy, the sleeve provides a solid mechanical barrier that prevents softer seal materials from deforming or flowing into clearance gaps under ultra-high pressure.

Applications:

• Positioned within the high-pressure cylinder sealing stack to support O-rings and dynamic seals

• Prevents seal extrusion in the plunger gland assembly during the compression stroke

• Compatible with 60,000 PSI, 15 GPM waterjet intensifier pumps

• Used in both hydraulic and high-pressure water sections of the intensifier

Features:

• High-Strength Material: Constructed from corrosion-resistant stainless steel or hardened alloy to withstand extreme pressure without deformation

• Precision Dimensions: Machined to exact tolerances for a perfect fit in the seal groove and against mating surfaces

• Anti-Extrusion Function: Fills the extrusion gap between the O-ring and the gland wall, protecting the primary seal from pressure spikes

• 15 GPM & 60k Rating: Engineered specifically for medium-flow, ultra-high pressure waterjet applications

Maintenance:

• Inspection: During pump overhaul, inspect the sleeve for signs of wear, scoring, cracking, or permanent deformation

• Replacement Criteria: Replace immediately if the sleeve shows any surface damage or loss of dimensional integrity. Reusing a worn sleeve can lead to O-ring extrusion and system pressure loss

• Installation: Ensure the sleeve is correctly seated in the groove, typically placed on the low-pressure side of the O-ring or dynamic seal

• Lubrication: Apply high-pressure grease to the sleeve and O-ring during installation to prevent pinching and ensure proper seating

• Full Depressurization: Always fully depressurize the waterjet system and follow lockout/tagout procedures before servicing
