Product Name: Pump Seal Repair Kit / Basic Pump Seals Kit (Part No. 303019)

Description:
The Pump Seal Repair Kit 303019 is a comprehensive OEM-grade maintenance kit designed for the complete overhaul of high-pressure waterjet intensifier pumps . This kit contains all the critical sealing components required to restore pressure integrity, cutting performance, and long-term reliability of pump systems operating at pressures up to 60,000 PSI (approximately 4,137 bar) .

According to manufacturer specifications, the kit includes the following components :

All components are precision-manufactured from premium elastomer and polymer materials designed to resist abrasion, temperature fluctuations, hydraulic fatigue, and chemical degradation from water and hydraulic fluids . These components are specifically engineered to maintain a perfect seal between the hydraulic and water sections of the intensifier, preventing leaks and pressure loss .

The kit is fully compatible with major waterjet systems including OMAX, KMT, FLOW, BFT, and WSI . It is also compatible with the AccuStream brand, with the corresponding AccuStream part number being 1-11989 .

Applications:

• Complete overhaul of OMAX, MAXIEM, KMT, FLOW, and WSI waterjet intensifier pumps 

• Suitable for ultra-high pressure waterjet systems operating at 60,000 PSI and above 

• Ideal for scheduled preventive maintenance, performance restoration, and unplanned repair procedures 

Features:

• Comprehensive Kit: Contains all critical seals, O-rings, dynamic seals, static seals, and wear components for a complete pump rebuild 

• OEM-Grade Quality: Precision-manufactured to meet or exceed original equipment specifications 

• High-Pressure Rating: All components engineered for continuous operation at 60,000+ PSI (4,100+ bar) 

• Premium Materials: Components made from polyurethane (Disogrin 6865), Viton (FKM), and other high-performance elastomers for wear resistance and chemical compatibility 

• Multi-Brand Compatibility: Compatible with OMAX, KMT, FLOW, BFT, WSI, and AccuStream systems 

• Weight: Approximately 0.835 kg 

Maintenance:

When to Replace (Failure Diagnosis):

• Scheduled Preventive Maintenance: This kit is designed for use during scheduled pump major maintenance intervals to prevent unplanned downtime 

• External Water Leakage: Visible water weeping from the pump area or valve bodies indicates seal failure requiring immediate attention

• Pressure Drop: Inability to maintain rated cutting pressure (typically 30% or more drop) suggests internal seal wear

• Water Contamination in Hydraulic Oil: Milky or discolored hydraulic oil indicates seal failure allowing water intrusion past dynamic seals

• Performance Degradation: Slow intensifier cycling, erratic pressure output, or reduced cutting speed indicates seal wear

Inspection and Replacement Guidelines:

• Full Depressurization (Critical): Before any maintenance, fully depressurize the waterjet system (high-pressure water, hydraulic system, and air supply) and follow lockout/tagout procedures 

• Complete Kit Replacement: When performing a pump rebuild, replace all components in the kit simultaneously. Do not mix new components with old ones 

• Clean Room Conditions: Perform rebuilds in a designated clean area to prevent contamination of replacement parts with abrasive particles 

• Lubrication: Apply manufacturer-recommended high-pressure grease to all seals and O-rings during installation to prevent dry start-up and ensure proper seating 

• Torque Compliance: When reassembling, tighten all retaining components to the specific torque values listed in the equipment service manual

• Component Orientation: Ensure proper alignment and orientation of backup rings, dynamic seals, and static seals as illustrated in the service manual 

• Storage: Store spare kits in a cool, dry environment away from direct sunlight, ozone sources, and chemicals to prevent premature aging of rubber components
