The FCT45 hydraulic transformer
The hydraulic equivalent of an electric power converter
How the FCT45 converts and controls hydraulic power
The FCT45 operates as the core component in next-generation CPR-systems, converting energy with minimal loss. This transformer enables hydraulic systems to work smarter, delivering more power while consuming less fuel and generating less heat.
Efficient Floating Cup Technology
Power is transformed via a single fixed displacement device that runs on the multi-piston floating cup principle. The floating cup principle is the only principle that allows operation from standstill, without high friction losses and wear.
Three ports
The transformer features three connections:
- one linked to the high pressure CPR-line
- one linked to the low pressure CPR-line
- one linked to the load
Rotating port plate
A BLDC-motor equipped with an integrated controller adjusts the rotational angle of the port plates between 0° and 80° to regulate power conversion.

Technical specifications
The FCT45 functions effectively throughout its broad pressure operating range of up to 35 MPa (5100 PSI), maintaining reliable output even in challenging off-road environments. Its design enables pressure amplification capabilities that can exceed the supply pressure by as much as 50%.
This transformer is capable of producing flow rates as high as 200 l/min (53 GPM). Its Floating Cup principle offers distinctive advantages, enabling smooth operation at near-zero speeds under substantial load pressure.
The large number of pistons of the Floating Cup Principle effectively minimize torque, flow, and pressure fluctuations. Such reduction is critical for accurate and efficient management of hydraulic loads.
The transformer also functions in reverse mode, making it possible to recover valuable energy. The recuperated energy can be used for other loads, or stored in the hydraulic accumulator of the Common Pressure Rail.
Hydraulic transformers regulate loads directly where they are applied. These transformers connect to the Common Pressure Rail, functioning similarly to how electrical devices are plugged into an electrical power grid.
The FCT45 incorporates Floating Cup Technology as its foundational design principle. Initially created for use in pumps and motors, this technology is now utilized in Bucher Hydraulics' AX-series pumps and motors.
The transformer's high efficiency and energy recovery capability substantially decrease environmental impact while enabling smaller batteries and lower (sustainable) fuel consumption. Additionally, minimal energy losses allow for more compact cooling systems.

No, only if this is beneficial for loss reduction or for control reasons. In for instance an excavator, the boom cylinder and the swing are good candidates to be controlled by a transformer, but valve control might still be a good option for the bucket cylinder.
The CPR-system with transformers fundamentally alters the system. In numerous instances, the engine can be substantially reduced in size, the variable displacement pump can be substituted with a simple and considerably more efficient fixed displacement pump, and the coolers will be noticeably smaller.
Fuel savings depend on your specific application and operating conditions. The FCT45 reduces consumption significantly through advanced power management and efficient energy conversion. Contact our team for detailed performance data relevant to your equipment.
The port plate controls the torque on the internal rotor, resulting in a change of rotor speed and load pressure. This controls in the end the hydraulic power to the load.
The FCT45 is a hydraulic transformer that converts energy with minimal loss. Unlike conventional systems, it delivers more power while consuming less fuel and generating less heat. The FCT45 is the key enabling technology for the next generation of CPR-systems.
