Product ID: 05034798 – Snap Ring / Retaining Ring (Flange Hydraulic Seal Retaining Component)

Description:
This component is a snap ring, also known as a retaining ring or circlip, designed specifically for the hydraulic seal flange assembly in high-pressure waterjet intensifier pumps . It is a precision-engineered circular fastener manufactured from spring-tempered steel, featuring an open-end design that allows it to be compressed for installation into a machined internal groove. This snap ring functions as a mechanical retaining device, securing the flange and hydraulic seal components in their proper axial position within the intensifier assembly.

This part is specifically used on SL-V (75-100 HP) intensifier systems, SL-IV Plus, SL-V, SL-VI series pumps, and is compatible with HSEC (High Service Exchange Cycle) units . It is rated for ultra-high pressure operation up to 60,000 PSI (approximately 4,137 bar) . Alternative or cross-reference part numbers include 1-12578, WI012578, and 5000017 .

Applications:

• Used in waterjet intensifier pumps to retain the hydraulic seal flange assembly in position within the cylinder bore 

• Installed into precision-machined internal grooves within the hydraulic cylinder assembly to secure flange components

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

• Compatible with KMT SL-IV Plus, SL-V, SL-VI, HSEC units, and OEM intensifier assemblies 

• Two snap rings are required per complete intensifier assembly 

Features:

• Spring-Tempered Steel Construction: Provides high tensile strength, fatigue resistance, and durability under cyclic loading

• Precision-Stamped Design: Manufactured to exact dimensions for consistent fit within standard groove specifications

• Open-End Configuration: Features lug holes for installation using standard snap ring pliers

• Axial Retention: Provides reliable mechanical retention without requiring additional fasteners or threading

• Corrosion-Resistant Finish: Surface treatment (zinc plating or similar) for extended service life in wet operating environments

• Lightweight: Product weight is approximately 0.001 kg (0.002 lbs) 

• High-Pressure Rating: Designed for continuous operation at 60,000 PSI (4,137 bar)

Maintenance:

• Proper Tooling: Always use the correct size and type of snap ring pliers designed for internal retaining rings to avoid distorting the ring during removal or installation

• Inspection: Before reuse, inspect the snap ring for signs of deformation, bending, twisting, cracking, corrosion, or loss of spring tension

• Groove Inspection: Check the corresponding internal groove inside the cylinder bore or flange housing for wear, burrs, nicks, or damage that could affect proper seating of the snap ring

• Replacement Criteria: Replace any snap ring that shows signs of permanent deformation, cracking, fatigue, or corrosion. Do not attempt to reuse a damaged snap ring

• Full Seating: During installation, ensure the snap ring is fully and evenly seated in its groove. Partial seating may cause component failure under pressure

• Full Depressurization: Always fully depressurize both the hydraulic system and the high-pressure water system before disassembling any component secured by a snap ring. Follow lockout/tagout procedures

• Do Not Over-Expand: Avoid stretching a snap ring beyond its designed working range; over-expansion can cause loss of retaining force or permanent deformation

• Replacement Recommendation: When replacing seals or other internal components during pump overhaul, install a new snap ring as a best practice to ensure reliable retention

• Quantity Note: Two snap rings of this part number are required per complete intensifier assembly
