Hydraulic power units

The tailor-made superpower for hydraulic movements.
We manufacture hydraulic power units for almost all tasks in mechanical and plant engineering, including electronics and control, if required, ready for use.

Our goal: Aggregates that are optimally tailored to your area of application and deliver the required power efficiently and over a long timeOur goal: Hydraulic units that are optimally tailored to your area of application and deliver the required power efficiently and over a long period of time.

Thanks to our experience, we are also able to reduce noise emissions many times below the specified value of the work guidelines. It is also possible to produce units with ATEX CE marking. Large units with DNV approval, such as those used for transportation on oil platforms, are a specialty for our steel construction.

Frequently asked questions about AROS hydraulic units

What is a hydraulic unit?

A hydraulic unit is a compact unit for generating hydraulic energy, which consists of a pump, motor, tank and valves.

How does a hydraulic unit work?

The pump sucks liquid out of the tank, creates pressure and transfers it via valves to consumers, such as cylinders.

What are the main components of a hydraulic unit?

The core parts include motor, pump, hydraulic oil tank, filters, valves and accessories such as coolers or sensors.

Which technical data is important?

Pressure (bar), flow rate (l/min), output (kW), tank size and operating voltage are decisive.

How do I select the appropriate hydraulic unit?

Take into account the pressure, the flow rate (the volume flow), the movement cycle and the size of your drive units as well as the environmental conditions.

How do you calculate the required power for a hydraulic unit?

Use the following formula:
Power (kW) = (flow rate (l/min) × pressure (bar))/600.

Where are hydraulic units used?

They are typically used in industry and in classic mechanical engineering. They are used to achieve high forces with a compact design (presses, conveyors, etc.). In some cases, hydraulic units can also be found in large vehicles and mining equipment (conveyor belts for ore).

What are the benefits of AROS hydraulic units?

High power density in a small installation space. In addition, the acquisition costs are low and the technology is developed, tested and available worldwide. This makes it possible to implement even complex controls and movement patterns.

How is a hydraulic unit serviced?

The oil, as well as the filters, must be checked and changed regularly. The temperature is monitored and a regular functional test of the valves must be carried out.

Which hydraulic oil is suitable?

Select it based on viscosity, temperature range, and compatibility with seals and materials. Mineral hydraulic oils such as HLP 32 or HLP 46 are most commonly used.

What types of hydraulic units does AROS Hydraulik produce?

Stationary and mobile hydraulic units.

Why are AROS hydraulic units a good choice for industrial applications?

- Extremely robust construction
- Many years of experience in hydraulics
- We are a system supplier: Aggregate, cylinder and fasteners come from a single source
- Compliance with special standards or factory regulations is possible by arrangement
- Weltweite Erstatzteilverfügbarkeit

What equipment options are available with AROS hydraulic units?

Just about anything possible.

Does AROS also produce special solutions in small quantities?

Yes, that is the strength of AROS. We focus on small and medium-sized series in aggregate construction.

What information is required to design a hydraulic unit?

All required information can be viewed and completed in our Specification sheet PDF.
