Power packs

The hydraulic unit is the heart of every hydraulic system. The basic structure of a hydraulic power unit consists of a drive motor (e.g. electric motor, petrol or diesel engine), a hydraulic pump and a hydraulic tank. Each hydraulic power unit can be extended by appropriate hydraulic valves to realise the required function. We also assemble hydraulic power units according to customer requirements. Tell us which functions you need and we will assemble your hydraulic power unit with the corresponding components. Of course, every hydraulic unit is tested by us after assembly.

What is the function of a hydraulic power unit?

Hydraulic power units are used to supply oil and hydraulically control consumers.

How is a hydraulic unit constructed?

A hydraulic power unit is an independent assembly consisting of:

- Drive unit (e.g. electric motor, petrol or diesel engine, power take-off shaft or power take-off shaft gearbox).
- Hydraulic pump (e.g. gear pump, axial piston pump, vane pump)
- Hydraulic tank


Hydraulic power pack Structure



The drive unit is connected to and drives the hydraulic pump via a coupling. In compact units, the central flange is located between the drive motor, the hydraulic pump and the hydraulic tank. This flange serves, among other things, as a link between the drive unit, the hydraulic pump and the hydraulic tank, as well as for accommodating the hydraulic valves.
 

What must be considered when designing hydraulic units?

When dimensioning hydraulic power units, it is important to ensure that the required hydraulic power does not exceed the drive power of the drive unit. If the drive power is too low, the drive motor, for example, stops and can overheat. This can cause irreparable damage to the drive unit.
 

Which hydraulic oil can be used for hydraulic power units?

The selection of the right hydraulic oil depends on the area of application of the hydraulic unit. In most cases, a hydraulic oil HLP46 (kinematic viscosity (mm²/s) at 40 degrees Celsius) is sufficient.
