FAQ – KMT Piston Assembly (NEOLINE 40i Hybrid)

1. What is the NEOLINE 40i Hybrid piston assembly?

The NEOLINE 40i Hybrid piston assembly is a key high-pressure component in the NEOLINE 40i Hybrid waterjet pump. It consists of a complete piston unit and related parts designed to generate and sustain ultra-high pressure during operation.


2. What does the piston assembly do?

The piston assembly moves within the pump cylinder and works with seals and wear components to pressurize water to ultra-high-pressure levels. This pressurized fluid is then delivered to the cutting head for precise and efficient cutting.


3. Is this part compatible with my waterjet pump?

This piston assembly is specifically designed for NEOLINE 40i Hybrid waterjet pumps. It may not be compatible with other pump models unless explicitly listed. Always check your pump model before ordering.


4. Can I replace the piston assembly myself?

Replacing the piston assembly requires mechanical knowledge and proper tools. We recommend installation by a qualified service professional to ensure correct assembly, seal integrity, and reliable pump performance. find your KMT tools here


5. What other parts should be replaced at the same time?

For optimal performance and longevity, it’s recommended to inspect and often replace related parts when servicing the piston assembly:

  • Cylinder liners

  • O-rings and seals

  • Wear rings and bearings

  • Intensifier components
    These parts help maintain effective sealing and pressure stability.


6. How often should the piston assembly be serviced?

Service intervals depend on usage, operating conditions, and maintenance practices. Regular inspection during scheduled maintenance is recommended to avoid unexpected wear or failure.


7. Are OEM-equivalent replacement parts available?

Yes — we offer OEM-equivalent replacement piston assemblies and components designed for professional service and maintenance of NEOLINE 40i Hybrid pumps.
