Knuth Water-jetCutting System Hydro-Jet Eco 2040

Rigid Water-Jet Cutting System with small footprint and maximum operator comfort

completely equipped for Abrasive & Pure-Water Cutting
Flying Bridge Construction
space-saving design
state-of-the-art GPlus Cut control
axes are driven via preloaded ball screws

work area is open on three sides for comfortable loading
mechanical feed on Z axis
separately set up abrasives container with 1000 kg fill capacity

The Water-Jet is a universal tool with many benefits:

no thermal stresses, hardening, or tensions on the part
no dust, smoke or toxic fumes
small kerf width and very clean cut edges
virtually burr-free cuts = no rework necessary
direct plunge-cut at any position
very low mechanical stress on the part

High Pressure Pump Ecotron 40.37

maximum power and reliability for pure-water and abrasive cutting operations
maximum operator safety and low maintenance

hydraulic drive with axial-piston pump
Oil/water heat-exchanger for oil cooling system
pressure booster, complete with high-pressure tubing
Pulsation damper with pressure accumulator
relief valve integrated in the high-pressure circuit

The Hydro-Jet High-Pressure System with pressure transmitter is based on a high-pressure pump with hydraulic drive, pressure transmitter, pulsation damper, pre-filter unit, and pressure relief valve - all mounted on a common base frame.

The quick-relief valve maintains atmospheric pressure in the pipe system upon completion of the cutting process. Sound proofing enclosure is available to dampen the noise level and to protect the high pressure system.

A proportional valve to automatically control the water pressure via CNC control is included.
