The servo hydraulic solutions presented here are delivered plug & play. They have been tailored to the needs of specific applications, but they can also be adapted for other machine types.
Servo hydraulics
Servo hydraulic power pack type HS
Servo hydraulic power pack type HS
The servo hydraulic power pack type HS contains a very compact and powerful servo electric motor. Due to "Power on Demand" it impresses with high energy efficiency and can do without additional cooling. With the servo unit type HS, reversing operation can be realized without additional valve technology. It is also characterized by its small footprint, compact design and low noise emission. The unit is used in injection molding machines, machine tools, punching and bending machines, and straightening machines, among others.

- Flow rate Qmax: 50 lpm
- Rated power: 24.3 kW (per axis)
- Installation position: horizontal (cylinder module, tank module) or as necessary (servo power module)
Data sheet: D 6340
Electro-hydraulic drive type ePRAX® max
Electro-hydraulic drive type ePRAX® max
The patented ePRAX® electro-hydraulic drive combines the advantages of both drive technologies in a single, powerful and ready-for-connection system. Thanks to its hydraulics, it is powerful and durable, and it does not need any external oil lines due to its integrated design. Speed control takes place independently for each axis via the ePRAX controller. This drive has been specially optimized for press brakes and, through the targeted use of stored drop energy for the return stroke, it provides an extremely high level of dynamics while also achieving significant energy savings. The ePRAX® max complies with the valid accident prevention regulations and is certified with certificate of unit approval no. 13005.
Technical data
- Nominal force per machine: 1,100 to 1,700 kN (with two ePRAX max)
- Rapid speed: up to 230 mm/s
- Positioning accuracy: 5 µm
- Working stroke: 280 mm (standard)

Power module type MPLM
Power module type MPLM
Motor pump unit as link between electrical and hydraulic system.
In HAWE's motor-pump units, an electric motor and the hydraulic pump are directly connected via a flange. Different motor types and pump types can be combined. This makes it possible to generate emission-free hydraulic power from an electric drive train
Technical data
- Nominal force per machine: 1,100 to 2,500 kN (with two ePRAXs)
- Rapid speed: up to 230 mm/s
- Positioning accuracy: 5 µm
- Working stroke: 280 mm (standard)
