Dynamic Waterjet

Produces More Accurate Parts, at Significantly Higher Cutting Speeds

All waterjets exhibit stream lag and taper when cutting through material. Our patented Dynamic Waterjet® with Active Tolerance Control™ compensates for these inherent errors. Dynamic Waterjet produces more accurate parts at significantly higher cut speeds than parts cut with a standard waterjet. Utilizing advanced mathematical cutting models, SmartStream™ technology controls an articulated wrist to automatically tilt, compensating for the stream lag and taper.

With Dynamic waterjet you can cut parts 2 to 4x faster


Cut parts 2 to 4x faster than conventional flat stock waterjet cutting machines.

Waterjet cutting detailed design, illustrating quality part that can be cut quickly and accurately.


Gives you the ability to cut parts faster and more accurately than with a standard non-Dynamic waterjet.

Various stacked metals. Flow waterjets have true part stacking ability with consistent tolerance layer to layer.


True part stacking ability with consistent tolerance layer to layer.


Like all Flow waterjets, cut a variety of materials, such as metal, stone, glass, and composites.

Waterjet piercing material. Flow waterjets are easy to program.

Easy to Program

5-axis head articulations all occur behind the scenes automatically. No special training or waterjet cut part knowledge is required to gain the benefits of this technology.

Close up of pure waterjet cutting gasket. Waterjets are versatile. They can cut both soft and hard materials.


The Z axis can also carry the pure waterjet cutting head, thereby providing the ability to cut soft materials on the same machine.

Core Component Options

Flow's Paser 4 Cutting Head

PASER 4 UCL Cutting Head 

UCL (Ultra Component Life) technology extends orifice and mixing tube component life to a level that has yet to have been achieved in the industry. The UCL provides lower cost of operation as fewer parts are consumed and maintenance intervals are greatly extended.

At the core of our UCL technology is the Precision Orifice assembly. The Diamond Precision Orifice performs at 60,000 psi (4,150 bar) or 87,000 psi (6,000 bar) operating pressure reliably and repeatedly, lasting longer than ever before. Other grade orifice designs available for the Paser UCL head.

Unlike other cutting heads, the PASER 4 cutting head allows you to easily change the orifice assembly without having to replace the entire cutting head.  The advanced design eliminates the need for an expensive carbide mixing chamber spare part in the cutting head.

UltraPierce Vacuum Assist

UltraPierce Vacuum Assist 

Our exclusive UltraPierce™ Vacuum Assist technology provides reliable piercing of brittle and laminated materials such as marble, stone, glass, and composites.

Fragile materials such as these tend to form craters, cracks, or break during high pressure piercing. UltraPierce is a cutting head option that allows the Paser 4 to pierce these materials easily, saving time and raw material, as well as enhancing the quality of the finished product. UltraPierce's exclusive no clog design pulls abrasive into the cutting head a split second before the waterjet starts so that the waterjet has abrasive particles entrained in the jet stream immediately.
