OmniJet III Waterjet Cutting Head

The OmniJet Waterjet Cutting Head creates a coherent waterjet cutting stream and provides responsive on/off control for the UHP water. Its lightweight and compact size offers versatility in multi-directional water jet cutting applications with all motion control systems. Cutting performance, size, component service life and ease of maintenance make this the superior cutting tool for all waterjet cutting applications.
The OmniJet Waterjet Cutting Head is designed and tested for pressures up to 60,000 psi and orifice sizes ranging from .003 to .020 inches. The cutting head has a fail-safe valve design requiring air pressure to open. Water flow to the orifice is regulated by the needle and seat. For waterjet cutting, the orifices are premounted in a set-screw style retainer making them easy to change with an Allen wrench. Consistent stream coherency is achieved by stabilizing the water prior to entering the orifice.


The OmniJet has been rigorously tested under high-duty cycle conditions.  A unique seal and needle arrangement provides long life for all components, including the orifice.  The modual design makes replacing parts a quick and simple procedure.
