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

Description:
This component is a retaining ring (also known as a circlip or snap ring) specifically designed for BFT waterjet intensifier pumps, as listed in the CP022001/2 and HT022012/172 intensifier assemblies. It is a precision-engineered circular fastener manufactured from spring-tempered steel, featuring an open-end design with lug holes that allow for compression during installation into a precision-machined internal groove.

Within the BFT intensifier pump, this retaining ring is used to secure and position critical internal components such as seals, spacers, bearings, and pistons in their proper axial location 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 manufacturer parts documentation, this retaining ring is listed as a standard component in BFT intensifier assemblies, working in conjunction with other components including the cylinder (CP022002/190), piston sealing (XK121/220), wear ring (XF56/220), rod sealing (XST17/220), and back rings. The part number HT022044/103 is a direct OEM replacement for BFT waterjet systems.

Applications:

• Retains internal components (seals, spacers, bushings, bearings) within the high-pressure cylinder or intensifier assembly of BFT waterjet 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 a standard component in intensifier assembly parts diagrams

• Semi-Wear Part Classification: Under normal operating conditions, the retaining ring is not a high-wear consumable but should be inspected for deformation or damage during major overhauls

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: 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 (high-pressure water, hydraulic system, and air supply) 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

• Replace as a Set: When servicing the intensifier assembly, inspect and potentially replace related components such as cylinder (CP022002/190), piston sealing (XK121/220), wear ring (XF56/220), and back rings (CP022012/780, CP022015/527) simultaneously
