Product ID: 10110393 – Static Seal Assembly Repair Kit (SL-III / SL-IV Sealing Head)

Description:
This component is a static seal assembly repair kit, specifically designed for the sealing head (check valve assembly) of KMT waterjet intensifier pumps . As a precision maintenance kit, it contains the static sealing elements required to rebuild the stationary side of the high-pressure check valve system. The kit ensures leak-free operation by replacing worn static seals that prevent high-pressure water bypass within the sealing head assembly . This product is engineered for Streamline SL-III and SL-IV series intensifier pumps and is rated for ultra-high pressure operation up to 60,000 PSI (approximately 4,137 bar) .

Applications:

• Used to rebuild the static seal interface within the sealing head (check valve assembly) of waterjet intensifier pumps 

• Installed during scheduled preventive maintenance or when pressure loss due to internal bypass is detected

• Suitable for KMT Streamline SL-III and SL-IV series intensifier pumps operating at 60,000 PSI (approximately 4,137 bar) 

• Compatible with both 50 HP and higher horsepower intensifier configurations 

Features:

• Complete Static Seal Solution: The kit typically includes a static seal backup ring and a static seal element, providing all necessary components to service the static sealing interface 

• High-Pressure Compatibility: Engineered for continuous operation at 60,000 PSI (4,137 bar), ensuring reliable sealing under extreme pressure conditions 

• OEM Replacement: Direct replacement for KMT original equipment part number 10110393, maintaining factory specifications and performance standards 

• Sealing Head Component: Specifically designed for the SL-III/SL-IV sealing head assembly (Product ID 05116769), addressing static seal applications 

• Preventive Maintenance Essential: As a wear part kit, timely replacement of static seals is critical for preventing internal water bypass, pressure loss, and unstable pump operation 

Maintenance:

• Identify Seal Wear: Static seals degrade over time due to continuous high-pressure exposure, compression set, and temperature cycling . Signs of failure include pressure drop, unstable cutting performance, and visible water leakage from sealing head weep holes 

• Inspect Associated Components: During installation, inspect the sealing head body (Product ID 10106417 or 05116769) for internal bore wear, pitting, or scratches that could compromise the new seal . Check the plug seating surfaces and low-pressure inlet areas for out-of-round condition or damage 

• Full Depressurization: Always fully depressurize the waterjet system (both hydraulic and high-pressure water circuits) and follow lockout/tagout procedures before removing the sealing head or installing the static seal kit

• Surface Preparation: Thoroughly clean all sealing surfaces and O-ring grooves using a soft cloth and low-pressure water. Remove all debris, old seal residue, and mineral deposits. Do not use abrasive tools that could scratch sealing surfaces 

• Proper Lubrication: Apply manufacturer-recommended high-pressure grease or O-ring lubricant to static seals during installation to prevent pinching, rolling, or damage during assembly 

• Torque Compliance: When reinstalling the sealing head, tighten retaining components (gland nut, mounting screws) to torque values specified in the equipment service manual using a staggered tightening pattern to ensure even seal compression 

• Kit Integration: The 10110393 static seal repair kit is part of the broader sealing head assembly (Product ID 05116769) and is listed as a component within the SL-IV parts diagram (Item 6) . It is often replaced in conjunction with dynamic seal assemblies (e.g., 20422243) during comprehensive pump overhauls 

• Replacement Schedule: Establish a preventive maintenance schedule for static seal replacement based on operating hours rather than waiting for failure to avoid unplanned downtime. Replace when performing major intensifier rebuilds or when pressure instability is observed 

• Cross-Reference Information: This kit is the direct replacement for KMT OEM part number 10110393 and is used on SL-III and SL-IV intensifier systems . It may also be referenced as Seal Assy, Seal Head, SLIII/IV
