Product Name: Major Rebuild Kit (Part No. 302701)
Description:
The Major Rebuild Kit 302701 is a comprehensive OEM-grade maintenance kit designed for complete overhauls of high-pressure waterjet intensifier pumps and cutting head assemblies . It is manufactured by AccuStream (a Hypertherm brand) and is compatible with OMAX, MAXIEM, KMT, FLOW, BFT, and WSI waterjet systems . The kit contains all critical components necessary to restore the pump’s original performance, ensuring reliable high-pressure sealing, smooth actuation, and consistent water flow control under demanding cutting conditions . Cross-reference part numbers include AccuStream 1-12016, OMAX O302701, and RSAC12016 .
Kit Contents (Typical):
Based on component listings, this major rebuild kit includes high-pressure seals, O-rings, backup rings, valve seats, springs, wear guides, ceramic plungers, dynamic seals, check valve components, and liquid displacers . The complete scope of replacement parts covers both the high-pressure water section and the hydraulic oil section of the intensifier pump.
Applications:
Used for complete overhaul of waterjet intensifier pumps and on/off valve assemblies
Restores pump performance after extended service life or component failure
Suitable for ultra-high pressure waterjet systems operating at 60,000 PSI (approximately 4,137 bar) and above
Compatible with OMAX, MAXIEM, AccuStream, KMT, FLOW, BFT, and WSI systems
Features:
Comprehensive Overhaul Solution: Contains all necessary components for a complete pump rebuild in a single kit
OEM Quality: Manufactured by AccuStream (Hypertherm brand) to original equipment specifications
High-Pressure Rating: Engineered for continuous operation at 60,000+ PSI

Multi-Brand Compatibility: Interchangeable with OMAX O302701, AccuStream 1-12016, and RSAC12016
Maintenance:
When to Rebuild (Failure Diagnosis):
Performance Degradation: Significant pressure drop (typically 30% or more from normal operating pressure)
External Leakage: Visible water weeping from pump seals, valve bodies, or weep holes
Hydraulic Oil Contamination: Milky or discolored hydraulic oil indicates water intrusion past seals
Overheating: Pump components or intensifier cylinders running hotter than normal
Scheduled Prevention: Manufacturers recommend major rebuild every 4,500–5,000 operating hours or as part of preventive maintenance program
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 performing a complete overhaul, 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 Classification:
According to OMAX/AccuStream service documentation, the major rebuild kit components are classified as "Replace" items during Major Maintenance procedures. This kit represents a complete overhaul solution for the pump wet-end assembly.
