Compatibility

Part Number: 05116769

Designed for:

  • KMT-style High Pressure Intensifier Pumps
  • .875" Plunger Systems
  • 55,000 PSI (3,800 Bar) operating pressure
  • SL-IV series waterjet pumps utilizing the washer-style inlet poppet design.

Always verify your equipment model and part number before ordering.

 

Assembly Includes

The complete sealing head assembly consists of precision-engineered components, including:

  • Sealing Head Body
  • Poppet Retainer
  • Inlet Poppet Check Valve
  • Compression Springs
  • Gland Nut
  • Poppet Pin
  • Valve Seat
  • Discharge Poppet Check Valve

These components work together to maintain reliable high-pressure sealing and efficient water flow throughout the intensifier system.

 

Why Replace Your Sealing Head Assembly?

Over time, continuous exposure to ultra-high-pressure operation causes internal wear that can lead to:

  • Pressure loss
  • Reduced cutting performance
  • Water leakage
  • Premature seal failure
  • Increased maintenance frequency
  • Reduced pump efficiency

Replacing worn assemblies with a HJ WATERJET sealing head restores system performance and helps extend the life of your waterjet equipment.
