Minor Rebuild Kit 302700
Product Name: Minor Rebuild Kit / Minor Maintenance Kit (Part No. 302700)
Description:
The Minor Rebuild Kit 302700 is an OEM-quality maintenance kit designed for servicing the on/off valve assembly and cutting head components of high-pressure waterjet cutting systems . It contains all essential high-wear components required to restore proper valve sealing, smooth actuation, and consistent water flow control .
The kit components are precision-engineered from high-performance polymer and elastomer materials formulated to withstand continuous exposure to ultra-high pressure (up to 60,000 psi / 4,137 bar), temperature variations, and abrasive waterjet environments . All parts meet OEM specifications for perfect compatibility and fit .
According to manufacturer documentation, this kit includes the following components :
(3) Backup Ring Assembly, Brass (302244)
(1) Inline Filter Element, 9/16 inch (304104)
(2) O-Ring (200377)
(3) O-Ring (300733)
(3) O-Ring (200909)
(3) Dynamic Seal Assembly (302950)
(3) Seal, Dynamic (301639)
(3) Lip Seal (202398)
(2) O-Ring (300726)
(2) Backup Ring (200905)
Applications:
Used for scheduled Minor Maintenance of waterjet intensifier pumps
Servicing the high-pressure on/off valve and cutting head assemblies
Restoring sealing integrity and actuation performance of waterjet valves
Suitable for ultra-high pressure waterjet systems operating at 60,000 PSI (approximately 4,137 bar)
Compatible with OMAX, MAXIEM, KMT, FLOW, BFT, and WSI waterjet systems
Features:
OEM Quality: Manufactured to meet or exceed original equipment specifications
Comprehensive Solution: Contains all critical seals, O-rings, backup rings, and filter elements for minor pump maintenance
High-Pressure Rating: All components engineered for continuous operation at 60,000+ PSI
Premium Materials: Components manufactured from high-grade polymer and elastomer materials with exceptional resistance to pressure fatigue, corrosion, and abrasion
Service Classification: Designated as a "Replace" component during Minor Maintenance procedures
Maintenance:
When to Replace (Failure Diagnosis):
Scheduled Preventive Maintenance: The minor rebuild kit is designated as a "Replace" component during scheduled Minor Maintenance intervals
Valve Performance Degradation: If the on/off valve fails to seal completely, resulting in water dripping from the mixing tube when the valve is supposed to be closed
External Water Leakage: Visible water weeping from the valve body or cutting head connections indicates seal failure requiring kit replacement
Pressure Drop: Inability to maintain rated cutting pressure may indicate wear of internal sealing components
Irregular Actuation: If the valve opens or closes sluggishly or inconsistently
Installation Guidance:
Full Depressurization (Critical): Before any maintenance, fully depressurize the waterjet system (high-pressure water, hydraulic system, and air supply) and follow lockout/tagout procedures
Clean Room Conditions: Perform rebuilds in a designated clean area to prevent contamination of replacement parts with abrasive particles
Use All Components: When servicing, replace all components included in the kit simultaneously. Do not mix new components with old ones
Proper Lubrication: Apply manufacturer-recommended high-pressure grease to seals and O-rings during installation to prevent dry start-up
Torque Compliance: Tighten all retaining components to the specific torque values listed in the equipment service manual
Component Orientation: Ensure proper alignment and orientation of seals, backup rings, and wear guides as shown in the service manual
Service Context:
The Minor Rebuild Kit 302700 is a key component of the Major Maintenance Kit 302701
Regular replacement of these wear components keeps the valve operating smoothly, prevents leaks, and extends the lifespan of more expensive assemblies such as valve bodies and stems
