The transaction is mentioned in Bucher Industries’ Annual Report 2025: "Innovative piston pumps for lowest speedsThe “AX pump” from Bucher Hydraulics operates with low levels of noise, pulsation and vibration. In addition, it is extremely resilient, with a maximum pressure of 500 bar, and very efficient. The “AX pump” can be used for mobile electric machinery, such as earth-moving equipment, excavators and construction cranes. It is also an essential component of “Helax”, a hydraulic-electric drive that can even recover energy and reuse it immediately. In the reporting period, Bucher Hydraulics acquired the patent rights for the “Floating Cups” that are central components of both “AX pumps” and “Helax”.”Innas maintained all rights on the Hydraulic Transformer including the rights to use and exploit Floating Cup technology in hydraulic transformers.

CPR-systems redefine hydraulic performance
The FCT45 unlocks a new class of hydraulic architecture. CPR-systems represent the platform where efficiency meets productivity and reliability in the harshest environments. CPR systems work with every power source.
CPR-systems are based on a simple Common Pressure Rail
The hydraulic accumulators of the CPR are the super-caps of the system
The CPR is similar to the electric grid: a simple, well defined power supply
CPR-systems provide flexibility in power sourcing, allowing you to choose batteries if desired without requiring them.
CPR-systems strongly reduce the fuel consumption, or the amount of batteries you need to install
The strong loss reduction makes it possible to use much smaller coolers.
