Product ID: 05130091 – Hydraulic Cartridge Seal Assembly

Description:
This component is a hydraulic cartridge seal assembly, also known as a hydraulic cartridge or hydraulic seal cartridge, designed for high-pressure waterjet intensifier pumps . It is a pre-assembled unit that contains precision dynamic seals, O-rings, and backup rings configured specifically for the hydraulic (low-pressure) side of the intensifier pump . The cartridge is designed as a serviceable assembly that can be removed, rebuilt, and reinstalled without requiring special skills or extensive pump disassembly .

This cartridge is compatible with intensifier pumps utilizing a .875 inch (7/8") plunger and is rated for both 60,000 PSI (approximately 4,137 bar) and 90,000 PSI (approximately 6,200 bar) operation . Alternative or cross-reference part numbers include 05009030, 1-12107, 5000019, 80084759, 104954, and 6104954 .

Applications:

• Used in waterjet intensifier pumps to seal the hydraulic (oil) side of the reciprocating piston assembly, separating hydraulic fluid from the high-pressure water section .

• Installed within the hydraulic cylinder body, surrounding the piston rod or plunger, to prevent hydraulic oil leakage and contamination .

• Suitable for ultra-high pressure waterjet systems operating at 60,000–90,000 PSI (approximately 4,137–6,200 bar) .

• Compatible with KMT pump models including PRO I, PRO II, PRO III, SL-IV, SL-IV Plus, SL-V, SL-VI (15–60 HP and 100 HP Dual Topworks), and some late-model HSEC Neoline pumps .

• Also compatible with WSI K-Series waterjet pumps (30–60 HP) .

Features:

• Pre-assembled configuration ensures correct seal orientation and stacking order, reducing installation errors .

• Manufactured from high-pressure-rated materials including polyurethane, PTFE, and high-durometer elastomers for extended service life.

• Includes anti-extrusion backup rings to prevent seal deformation under high-pressure cycling .

• Designed for dynamic sealing applications on the reciprocating piston or plunger assembly .

• Rated for continuous operation at 60,000 PSI and 90,000 PSI pressure classes .

• Requires a specific seal installation tool (KMT Part No. 05009048) for proper seal replacement into the cartridge body .

• Replacement cartridge repair kits are available (e.g., 80084759) for rebuilding the seal assembly .

Maintenance:

• Cartridge Overhaul: The hydraulic cartridge is a serviceable component. When seals wear, the cartridge can be removed and rebuilt using a dedicated repair kit (e.g., 80084759) .

• Seal Replacement: All dynamic seals, O-rings, and backup rings within the cartridge should be replaced as a set. Do not reuse individual seals from an old cartridge .

• Special Tool Requirement: Installation of new seals into the hydraulic cartridge body requires a specific seal installation tool (Part No. 05009048) to prevent seal damage during assembly . Do not attempt seal replacement without the proper tool.

• Inspection Criteria: During pump overhaul, inspect the cartridge for external leakage, seal extrusion, or signs of hydraulic oil bypass. Replace or rebuild the cartridge if any leakage is detected.

• Compatibility Verification: Before installation, verify that the cartridge is compatible with the specific pump model (PRO series, SL series, .875 plunger) and pressure rating (60K or 90K) .

• Full Depressurization: Always fully depressurize both the hydraulic system and the high-pressure water system before removing or servicing the hydraulic cartridge. Follow lockout/tagout procedures.

• Replacement Interval: Replace or rebuild the hydraulic cartridge seal assembly as part of scheduled preventive maintenance based on operating hours, or when signs of hydraulic oil leakage or pressure instability appear.

• Torque Compliance: When reinstalling the cartridge, tighten all retaining components to the torque values specified in the equipment service manual to ensure proper seating and prevent leaks.
