Product Name: Snap Ring / Retaining Ring (Part No. 200913)

Description:
This component is a snap ring, also known as a retaining ring or circlip, specifically designed for use in high-pressure waterjet cutting systems and intensifier pumps . It is a circular fastener manufactured from stainless steel, featuring an open-end design that allows it to be compressed for installation into a precision-machined internal groove .

This snap ring is specifically used as a retaining component in the coolant housing or bushing block assembly of the waterjet intensifier pump . Its primary function is to secure and position internal components such as seals, bearings, bushings, and pistons in their proper axial location, preventing movement or displacement during high-pressure operation.

The snap ring is an OEM direct replacement part for OMAX EnduroMAX and OMAX Maxiem direct drive waterjet pumps, with cross-reference part numbers including WO040021, KMT 200913, and AccuStream 1-13140 . Its weight is approximately 0.001 lbs .

Applications:

• Retains internal components within the coolant housing assembly of waterjet intensifier pumps

• Secures seals, bearings, and bushing components in position under high-pressure operation 

• Installed into precision-machined internal grooves within the cylinder bore or housing

• Used on OMAX EnduroMAX, OMAX Maxiem, and KMT waterjet intensifier systems 

Features:

• Stainless Steel Construction: Provides excellent corrosion resistance and strength in waterjet environments 

• Precision Dimensions: Bore diameter of 9/16 inch for secure fitment in designated grooves 

• Retaining Function: Secures internal components and prevents axial movement under pressure 

• OEM Compatibility: Direct replacement for OMAX 200913, KMT 200913, and WO040021 

• Lightweight: Approximately 0.001 lbs for easy handling during maintenance 

Maintenance:

Failure Diagnosis:

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

• External Leakage: Water weeping from the coolant housing area may indicate snap ring failure allowing seal movement

• Visible Damage During Inspection: Check for deformation, cracking, corrosion, or loss of spring tension

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

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 

• Inspect During Overhaul: During pump or coolant housing maintenance, remove and inspect the snap ring for signs of fatigue, distortion, or damage

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

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

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

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

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

• Storage: Store spare snap rings in a clean, dry environment away from corrosive substances
