Product Name: Retaining Ring / Snap Ring (Part No. HT022044/103)

Description:
This component is a retaining ring, also known as a snap ring or circlip, specifically designed for BFT waterjet intensifier pumps . It is a precision-engineered circular fastener manufactured from spring-tempered steel, featuring an open-end design that allows for compression during installation into a precision-machined internal groove.

The retaining ring functions as a mechanical stop, securing internal components such as seals, spacers, bushings, and bearing rings in their proper axial position within the high-pressure cylinder or hydraulic end assembly . It prevents component displacement or movement during high-pressure operation up to 60,000-94,000 PSI (approximately 4,137-6,480 bar). According to BFT parts diagrams for intensifier assemblies CP022001/2 and HT022012/172, this retaining ring is listed as Item 5 .

Applications:

• Secures internal components (seals, spacers, bushings) within the high-pressure cylinder or hydraulic end assembly of BFT waterjet intensifier pumps

• Provides axial positioning and prevents component movement under high-pressure cycling

• Used during scheduled preventive maintenance, major pump overhauls, or when component retention is compromised

• Compatible with BFT intensifier assemblies CP022001/2 and HT022012/172

Features:

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

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

• Precision Dimensions: Manufactured to exact tolerances for consistent fit within standard groove specifications

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

• Corrosion-Resistant Finish: Surface treatment for extended service life in wet operating environments

• Direct OEM Replacement: Interchangeable with BFT part number HT022044/103, listed as Item 5 in intensifier assembly parts diagrams

Maintenance:

Failure Diagnosis (When to Inspect/Replace):

• Component Movement: If internal parts shift or become misaligned, the retaining ring may have lost its retaining force

• External Leakage: Water or hydraulic oil weeping from the cylinder area may indicate retaining ring failure allowing seal movement

• Visible Damage During Inspection: Inspect the retaining ring for signs of deformation, cracking, corrosion, or loss of spring tension

• Noise or Vibration: Unusual sounds during pump operation may indicate loose internal components due to retaining ring failure

• Scheduled Overhaul: It is standard practice to inspect retaining rings during major pump overhauls and replace them if any wear or damage is detected

Inspection and Replacement Guidelines:

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

• Groove Inspection: Before installing a new retaining ring, inspect the corresponding internal groove for wear, burrs, or damage that could affect proper seating

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

• Replacement Criteria: Replace the retaining ring immediately if cracks, deformation, corrosion, or loss of spring tension is observed. Do not reuse a damaged retaining ring

• Full Depressurization: Always fully depressurize the waterjet system and follow lockout/tagout procedures before removing or servicing components secured by this retaining ring

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

• Cross-Reference Information: This retaining ring is listed as Item 5 in BFT intensifier CP022001/2 parts list and Item 5 in HT022012/172 parts list
