Mining
Mining plays a central role in securing the global supply of raw materials. At the same time, it places the highest demands on the reliability of the technology and machines used. With our many years of expertise and innovative product solutions, we're your reliable partner for successfully mastering any challenge – for maximum system availability and ultimate safety.
Components, systems & solutions for all mining sectors
Underground mining
High temperatures and humidity, dust formation and vibrations make it difficult to use machines and technology underground. With robust and proven product solutions, we ensure long intervals between maintenance and a long service life for your underground mining equipment.
Surface mining
In surface mining, machines are exposed to extreme weather conditions, dust and contamination. High standards for the cooling, filtering and reliability of the hydraulic systems ensure that the machines work efficiently and without errors even when in continuous use.
Tunnel construction
Due to the limited space available, compact yet powerful solutions are particularly in demand in tunnel construction. We contribute to optimum space utilisation with integrated system solutions from the filtration, cooling and drive technology sectors.
Deep-sea mining
For the extraction of raw materials below the sea surface, we offer special cylinders, filtration systems and accumulators for pressure compensation that reliably withstand the prevailing pressure conditions and the corrosion caused by salt water in deep-sea mining.
System availabilityTried-and-tested product solutions for the special requirements in mining
The extreme working conditions in mining demand maximum performance from machines and systems as well as people. High temperatures, constant exposure to dust and high humidity accelerate component wear and often lead to unplanned downtimes.
With our tried-and-tested product solutions in the fields of hydraulics, filtration, cooling, valve technology and pumps, we minimise maintenance costs while increasing the reliability of your systems in surface or underground mining. This reduces unplanned downtimes and maximises operating times.

HYDAC process filters
We offer our customers a wide range of process filters for underground and surface water filtration in the mining industry, e.g. for shield spraying in cutting machines, cooling water treatment for mine ventilation, protective filtration for underground water hydraulics or the filtration of HFA and HFD fluids.
HYDAC mounting technology
Our HYDAC mounting solutions can be used to securely fasten accumulators, tanks, cooling elements and supply lines in mining.
We offer you a wide range of pipe, hose & cable mounts, band straps and accumulator mounting elements.
HYDAC Heavy Duty solutions
For use in particularly challenging conditions and with high loads, we also offer many of our mining solutions as special heavy duty versions. They are characterised by their high load capacity, durability and resistance.
Explosion protection
ATEX-certified systems and components play a crucial role in mining as they enable safe operation in potentially explosive atmospheres. By complying with strict European directives, these certified solutions offer a high level of protection against sparks and potential explosions caused by dust or gases. ATEX-certified systems therefore make a significant contribution to ensuring safety underground.
We offer you a wide range of explosion protection solutions in an ATEX version, such as sensors, coolers, pumps, drive systems, cylinders and filter systems.

HYDAC air coolers AC-LN ATEX / AC-LNH ATEX for cooling lubrication oil or hydraulic oil
With its antistatic fan, earthed components and ATEX-certified fan drive, our solution is particularly suitable for areas at risk of gas and dust explosions. Our air cooler is available with an AC motor (AC-LN) or a hydraulic fan drive (AC-LNH) with 50 Hz and 60 Hz.
HYDAC's valve range with explosion protection for maximum safety in mining
For use in potentially explosive atmospheres in surface and underground mining, our valves are also available with ATEX certification on request, e.g. HYDAC industrial solenoid valves in a spool design, HYDAC industrial solenoid valves in a poppet design, HYDAC industrial proportional valves 3-way pressure control valve, HYDAC hydraulic valves or HYDAC cartridge solenoid valves in a poppet design.
HYDAC filter systems for maximum explosion protection in mining
Our filter systems such as the HYDAC vacuum dewatering unit FAM ATEX, the HYDAC Condition Monitoring Package CMP EX, the HYDAC OffLine Filter OLF ATEX and the HYDAC filter pump transfer unit in OFU ATEX enable the best possible safety in potentially explosive atmospheres.
HYDAC sensors for potentially explosive atmospheres
HYDAC offers you an extensive range of sensors for the special requirements of underground mining. Our product range includes pressure transmitters, pressure switches, temperature transmitters and flow rate transmitters, for example.
System engineering
System solutions for mining equipment offer decisive advantages over the use of individual components. The optimum coordination of all components maximises efficiency while reducing downtimes and extending the service life of the entire system.
HYDAC offers you tailor-made complete solutions from a single source that minimise maintenance costs and reduce the total cost of ownership as well as facilitating integration.
