Product Name: waterjet pump Spare Parts

Description:
Waterjet pump spare parts are replacement components designed for high-pressure intensifier pumps used in waterjet cutting systems. These parts enable routine maintenance, repair, and complete overhaul of pumps rated for operation at 60,000–90,000 PSI (approximately 4,137–6,200 bar). Common spare parts include seal assemblies, seal kits, valves, cartridges, rings, plungers, and hydraulic components. They are precision-engineered to ensure proper fit, leak-free operation, and extended service life under extreme pressure cycling.

Applications:

• Used for servicing waterjet intensifier pumps including SL-V, SL-IV, SL-IV Plus, SL-I, SL-II, Jelline JL-1, and Neoline series pumps

• Installed during scheduled preventive maintenance or when performance degradation occurs (pressure drop, leakage, unstable operation)

• Suitable for both pure water and abrasive waterjet cutting systems

Features:

• High-Pressure Rating: Engineered for continuous operation at 60,000–90,000 PSI (4,137–6,200 bar)

• Precision Manufacturing: Components machined to exact tolerances for proper fit and leak-free operation

• Wear-Resistant Materials: Seals manufactured from polyurethane, PTFE, and high-durometer elastomers 

• Consumable Design: Parts are designed as wear components requiring periodic replacement

• Kit Configurations: Available as complete seal kits, repair kits, or individual components 

• Corrosion Resistance: Materials selected to withstand water exposure and water treatment additives

Maintenance:

• Performance Monitoring: Replace spare parts when symptoms appear: drop in cutting pressure, visible water leakage from weep holes, increased pump cycling frequency, or water contamination in hydraulic oil 

• Preventive Replacement: Replace consumable parts (seals, O-rings, backup rings) on a schedule based on operating hours rather than waiting for failure

• Clean Installation: Perform maintenance in a clean area; wear gloves to prevent introducing oils, debris, or abrasive particles to new components 

• Lubrication: Apply manufacturer-recommended high-pressure grease to seals and O-rings during installation to prevent dry startup and ensure proper seating 

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

• Associated Component Inspection: When replacing seals, inspect the plunger and cylinder bore for scoring, pitting, or wear—a damaged plunger will rapidly destroy new seals 

• Water Quality Impact: Poor water quality with contaminants accelerates seal wear; maintain proper water filtration

• Torque Compliance: Tighten all connections to torque values specified in the equipment service manual

• Cross-Reference Verification: Verify spare part cross-references before installation; many parts have multiple OEM part numbers
