  • For preventative fluid servicing and increased operating safety

 

Portable data recorders

  • For service, commissioning and maintenance
  • For recording, displaying, processing and storing measurement data

Accumulator technology

Storage of all functional principles for every application:

  • Energy storage for brake systems
  • Smoothing of pump pulsations
  • Damping of pressure peaks
  • Chassis suspension
  • Weight equalization
  • Attachment suspension
  • Silencer for substantial reductions in noise emission

Controls, working and additional hydraulics

Mobile controls as a complete package of: hydraulics, sensors, electronics and software; everything from one source or as individual components.

HYDAC offer mobile valves for standard actuation types (manual, hydraulic, pneumatic, electronic or electro-proportional) on different hydraulic circuits and options. Whether in open or closed circuits, in monoblock or disk construction, or a combination of the two; also available with load-sensing controls. In this way we have created a modular system for flexible design of your complex controls up to approx. 180 l/min and for pressure ranges of up to 350 bar.

  • Constructional design as monoblock, in disk construction or a combination of the two,
  • setting functions with and without load pickup,
  • use with constant or adjustable pump possible,
  • a multitude of control valve pistons and characteristics is available,
  • main consumer in parallel or series switching,
  • easy integration of secondary functions,
    • of load-holding and load-lowering brake valves,
    • of the priority valve for steering (OC or LS steering),
    • of the priority valve for the brake system with integrated accumulator charging function,
    • of pressure filters and accumulators (for emergency functions),
    • of pressure and position sensors,
    • Level control

Emergency steering pump kit

Should the power supply for the steering system fail, the vehicle can be brought safely to a halt.

Tank-filter solutions

Complete systems ready for installation, optimized with reference to component protection, system cleanliness and ventilation.

Diesel tanking pump kit

This is possible on the vehicle independent of a stationary tanking system.

Filtration solutions

A comprehensive range of hydraulic and ventilation filters equipped with high-quality filter element materials ensure high operating safety and long maintenance intervals, for example:
Return filtration with return filter RFM

  • as tank-mounted or tank-integrated filter
  • for tank integration (set version) up to 2,000 l/min

 

Feed circuit filtration with line filter LPF

Pressure oil filtration with line filter MFM

Removal of coarse particles with Inline Filter ILF

Air filtration with ventilation filters BF, ELF, ELFL, BD

  • Broad standard product range
  • Optionally available with duo valve for tank pre-tension
  • Anti-swash protection possible
  • Version with air-drying function

 

Filter clogging indicators For improvement of operating safety and, if applicable, display of maintenance intervals

Brand labeling to ensure availability of spare parts Marking of the filter elements for improvement of the product identification and to ensure replacement element availability

Cooling systems

High-power and installation-optimized cooling systems are available for fulfillment of the legal requirements for noise, emissions (EURO 4, TIER 3) and savings in fuel.

  • Integrated thermo-bypass valves
  • Electric / hydraulic drives with proportional speed control available
  • Multiple combination cooling systems available

Customer-specific central hydraulics

Here individual components such as valves, accumulators, filters and partial systems can be integrated together into one block.

The advantages:

  • Space-saving
  • Reduction of leakage outwards
  • Reduced assembly time and effort
  • Economic with material
  • Tailored to the specific installation situation
