DynaMAX 3-series waterjet pumps

Available in three power levels, DynaMAX™ (Echion™) 15, 30, and 50 waterjet pumps deliver consistent cut quality at optimum cutting speeds and a design that simplifies service so maintenance is faster, easier, and less expensive. At the same time, DynaMAX pumps include features like fully integrated cooling for a smaller footprint that enables easy integration into small spaces.


System information


Reduced maintenance time

DynaMAX 3-series waterjet pumps include the next evolution of Hypertherm’s Advanced Intensifier Technology™ (AIT). This technology eliminates soft, static high-pressure seals and incorporates industry-leading cartridge seal design, enabling rapid replacement of common consumables.


Increased performance

Standard on all DynaMAX 3-series pumps, closed‑loop proportional pressure control adjusts for ambient pressure and temperature, oil viscosity and hydraulic system wear parts, to deliver consistent quality at optimum cutting speeds.

Improved reliability and ease of service

With 20% fewer parts than earlier generations, DynaMAX 3-series pumps include user-friendly features such as common service components located front and center, quickconnect fittings, and an easy access bleed‑down valve, to make maintenance faster, easier, and less expensive.
