Buying advice

Choosing the right Hydac component

Selecting the right filter

The choice of filter follows the installation point and the task: pressure filters protect sensitive parts on the high pressure side, return line filters clean the oil flowing back to the tank, and line filters sit in the pipework. Mind the nominal pressure, port size and the required filter grade.

Cooling and temperature control

Overheated hydraulic oil ages faster and loses its lubricating effect. Standard coolers and plate heat exchangers keep the fluid within the permitted temperature window. Size them by the heat load to be dissipated, the flow rate and the available cooling medium.

Monitoring with measuring and sensor technology

Hand-held measuring devices and sensors record pressure and flow rate - for diagnosis, commissioning and continuous monitoring. That way you spot deviations early and plan maintenance ahead of time.

FAQ

Frequently asked questions about Hydac

What does Hydac manufacture?

Hydac is a German manufacturer of hydraulic and fluid technology. The programme covers filters, coolers and heat exchangers, valves plus measuring and sensor technology for industrial and mobile hydraulics.

Which filter types does Hydac offer?

Hydac offers pressure filters (DF ON series), return line filters (RF ON series) and line filters (LF ON series), among others. They differ in installation point, pressure range and task within the hydraulic circuit.

What are Hydac coolers and heat exchangers used for?

Standard coolers and plate heat exchangers keep the hydraulic oil within the permitted temperature range. That slows the ageing of the oil and preserves its lubricating effect, which supports the service life of the system.

Which measuring technology does Hydac offer?

Hydac carries hand-held measuring devices such as the HMG series plus sensors, for example for pressure and flow rate. They are used for diagnosis, commissioning and the continuous monitoring of hydraulic systems.
