Engineering standards and international structure of HYDAC Group

The engineering heritage of HYDAC began in Saarland in 1963 with the manufacture of hydraulic accessories under the original name Gesellschaft für Hydraulikzubehör.

Over six decades, the enterprise expanded into an international group encompassing 52 subsidiaries, 500 service partners, and more than 11,000 employees worldwide.

More than 900 specialized engineers in Germany dedicate their efforts to developing energy-efficient fluid technology solutions for industrial machinery.

Technical development programs follow strict DIN, ISO, and pressure equipment directive guidelines to ensure structural durability, operational safety, and extended operating cycles across all hydraulic drive installations.

Classification and engineering selection of HYDAC accumulators

HYDAC hydraulic accumulators deliver essential fluid power storage, machine damping, and thermal expansion compensation across demanding hydraulic circuits.

For high-speed mechanical press cycles, Series SB bladder accumulators provide rapid instantaneous discharge rates while occupying compact installation space.

Mobile machinery and compact machine tool clamping packages utilize Series SBO diaphragm accumulators, which feature lightweight construction and high shock tolerance.

Heavy-duty metallurgical rolling mills and metal extrusion presses benefit from Series SK piston accumulators with precision-machined barrels, enabling smooth high-temperature operation over large volumes.

Industrial fluid filtration technology and Betamicron filter elements

Protecting precision proportional spool valves and hydraulic pumps requires maintaining strict ISO 4406 fluid cleanliness standards throughout operating cycles.

HYDAC filter architectures rely on Betamicron BN4HC multi-layer microglass media elements, delivering beta efficiency ratings exceeding 200 for micron ratings from 3 to 20 micrometers.

Inline pressure assemblies Series DF handle cyclic mechanical pressures up to 420 bar, while return line filters RF incorporate fluid diffusers to prevent reservoir aeration.

The inorganic fiber structure resists synthetic and mineral fluids, ensuring deep particulate holding capacity without media breakdown under continuous flow conditions.

Electronic pressure transmitters, digital switches, and HMG recorders

Electronic pressure transmitters Series HDA 4000 feature durable stainless alloy or ceramic diaphragms with thin-film strain gauge bridges. These transmitters retain linear output curves under high-frequency hydraulic pressure spikes across fluid lines.

For visual operating feedback, Series EDS 3000 electronic pressure switches provide a rotatable LED display and configurable transistor output channels.

Portable diagnostic systems Series HMG 4000 enable maintenance technicians to record multi-channel sensor feeds simultaneously, capturing microsecond hydraulic pressure surges and cavitational fluid phenomena to support predictive service routines.

Industrial thermal management and oil cooler system sizing

Maintaining fluid temperatures between 45 and 55 degrees Celsius preserves hydraulic fluid viscosity and prolongs internal seal life. HYDAC air blast oil coolers Series AC-LN utilize specialized low-noise axial fans with aerodynamic blade profiles to minimize workshop acoustic levels.

When plant cooling water loops are accessible, copper-brazed compact plate heat exchangers Series HEX transfer substantial heat loads within minimal space boundaries.

Mobile cooling units OK-ELD powered by 12V or 24V direct current electric fan motors deliver continuous thermal regulation for industrial transmissions and mobile hydraulic power circuits.

Compact power unit design, integrated manifolds, and ball valves KHM

Modular hydraulic power packs Series CA and HYBOX integrate electric pump assemblies, aluminum or steel reservoirs, and directional valve networks into compact modular skids.

For dependable fluid isolation under demanding pressures, high-pressure ball valves Series KHM and KHP withstand operating loads up to 1050 bar without internal leakage.

The polished stainless ball rotates against wear-resistant polyoxymethylene seals, preventing binding under severe hydraulic loading.

Consolidating hydraulic logic onto multi-station manifold blocks eliminates exterior line fittings, reducing vibration risks and minimizing external fluid connection points.
