The Mobile and Industrial Product portfolio is as follows:

A Axial Piston Pumps & Motors
  Axial piston pumps are available in swashplate and bent-axis design for the medium and high-pressure range. Variations in the design, in the output range and in the open and closed-loop control options guarantee optimum solutions for stationary applications.
 

Performance profile

  • Displacement 5 to 1000 cm³
  • Nominal pressure up to 420 bar
  • Maximum speed up to 5600 min-1
  • Maximum power 933 kW
  • Modular controllers: hydrome¬chanical and electrohydraulic controllers
 
   
B External Gear Pumps & Motors
  Gear pumps are classic in the field of hydraulics.
Solo-pumps, multiple pumps and low-noise "silence" pumps in five series offer a multitude of applica-tion possibilities.
 

Performance profile

  • Displacement 1 to 56 cm³
  • Nominal pressure up to 280 bar
  • Pressure-related gap sealing and high manufacturing precision ensure optimum efficiency

I Proportional, High-Response and Servo-Valves
  Proportional valves
Many controls would hardly be conceivable without proportional valves with integral electronics (OBE). They reduce the cabling effort and simplify handling while offering exact reproducibility and low manufacturing tolerances.

Performance profile

  • Pressure and flow control and directional valve variants in sizes 6 to 52
  • Maximum flow 2800 L/min
  • Maximum operating pressure 350 bar
  • Proportional solenoid with electrical closed-loop position control for high accuracies (> 1 %)
  • Rugged electronics for stationary and mobile applications

  High-response valves
High-response valves are compact and robust. They are convincing in their high dynamics and control accuracy. The core product of size 6 and size 10 can be combined with main stages of up to size 160 with a nominal flow of up to 18000 litres.

Performance profile

  • Maximum flow 50000 Llmin Maximum operating pressure 420 bar
  • Sizes 6 to 160
  • Highly dynamic valves with zero overlap for use in closed control loops
  • Direct and pilot operated
  • For subplate mounting and block installation

  Servo-valves
Servo-valves are hydraulically pilot operated 2- or 3-stage directional valves with porting pattern to DIN 24340 form A. They are mainly used for closed loop-controls of position, force or pressure and velocity.
They are characterized by:
- Compact build
- Low electrical power consumption
- High dynamics and
- Excellent quasi-steady-state values
