The European Water Jetting Institute (EWJI) member AQUAJET has introduced a series of product developments covering robot controls, attachments and high-pressure pumps. The launches include Evolution 3.1 for the Aqua Cutter 450 and 750, an Evolution 3.1 option for Ergo Controller, three new attachments for the Aqua Cutter 450 and the Ecosilence 400 high-pressure pump.
“These developments give contractors more ways to adapt their equipment to the job,” said Roger Simonsson, CEO of Aquajet. “Evolution 3.1 supports the operator’s daily work and brings familiar controls to Ergo Controller, while the new Aqua Cutter 450 attachments and Ecosilence 400 broaden the choice of tools and pump capacity. Our focus is always on developing products that work together as a complete hydrodemolition solution, making setup and operation easier.”
Evolution 3.1 across three platforms
Both the Aqua Cutter 450 and 750 have been upgraded from Evolution 3.0 to Evolution 3.1. The updated control system is also available as an option for Ergo Controller, bringing Evolution controls and sensor support to Ergo and Aqua Rail applications.
This provides a familiar system foundation across three platforms, helping operators apply their existing Evolution knowledge when moving between machines and configurations.
New functions support the operator throughout the job. Turnpoint detection and Position hold assist controlled manual positioning, while clearer Shapes graphics, traverse reset and indexing end-stop functions support programming and setup. Operators can also start and stop the motor remotely.
USB software updates, diagnostics, alarms and service reminders support troubleshooting and maintenance. Evolution 3.1 retains support for 3.0 attachments, including power heads, Rotolances, Circular kit and Extension kits, as well as Ergo and Aqua Rail configurations.
New attachments for Aqua Cutter 450
The new Rotolance 450, Extension kit 450 and Circular kit 450 are available now, expanding the application possibilities of the Aqua Cutter 450.
Rotolance 450 comes in two versions for different pressure and flow requirements. Its tool range includes large and small spray bars, with double and triple nozzle options. The Extension kit provides additional reach, while the Circular kit enables work around circular structures.
Aquajet has also introduced updated protective covers for Rotolances on both the Aqua Cutter 450 and 750. Options include large and small round covers with vacuum extraction and a reversible protection cover.

Ecosilence 400 expands the pump range
The new Ecosilence 400 adds a 400 hp class solution to Aquajet’s high-pressure pump range. Available in standard and PRO versions, the unit combines a Volvo Penta engine with a five-cylinder Hammelmann pump and Revo 3.0 controls in a 20-foot container.
The additional capacity options give contractors more choice when matching a pump to their working equipment and applications.
Demonstrated as part of a complete worksite
Aquajet presented the developments to around 150 customers and partners during its Nordic and international Customer Days on 14–15 and 21–22 October at its new headquarters in Vetlanda.
Guided outdoor demonstrations featured Aqua Cutter robots, different pump configurations and attachments, with Ecoclear treating process water for recirculation. Indoor demonstrations showed Ergo Controller with Evolution 3.1 operating in several Aqua Rail configurations. Supporting technical presentations connected equipment selection and control settings with removal results and water management, demonstrating Aquajet’s complete hydrodemolition offering.
