HOW DOES A HYDRAULIC POWER UNIT WORK?
A hydraulic power unit is a unit that generates hydraulic energy (using a hydraulic pump) from a primary energy source (usually an electric motor or combustion engine) and supplies it to a hydraulic system. The power unit supplies hydraulic drives, cylinders and motors with pressure and volume flow by drawing hydraulic fluid from the tank and feeding it under pressure to the consumers via the valve control system. If everything is designed correctly, from the tank volume to the hydraulic pump to the control system, the system will operate reliably, consistently and efficiently. This applies to both stationary machines and mobile applications.
1. HOW IS A HYDRAULIC POWER UNIT CONSTRUCTED?
Each hydraulic unit consists of several components. A pump draws hydraulic fluid from the tank and brings it to a higher pressure level. Valves regulate flow and direction. An electric motor or other form of drive provides the movement. The entire hydraulic unit design is based on the application and local operating conditions. To ensure that the system can operate smoothly, the individual components must be coordinated with each other. The most important components of a hydraulic power unit are a drive type (usually electric or combustion engines with couplings), hydraulic pump, pressure relief valves, directional control valves, check valves, filters, pipe or hose lines and an oil tank with level indicator or sensors.
1.1 WHAT TYPES OF HYDRAULIC POWER UNITS ARE THERE?
There are various types, such as stationary, mobile, compact, high-pressure or customised units, depending on the requirements for the hydraulic unit.
1.2 HYDRAULIC UNITS FOR GROWING PLANTS
Manufacturing processes are constantly changing. Tools change, systems grow, processes become more complex. A hydraulic power unit adapts to these developments and expands its performance range when new tasks arise. Users adjust the pressure, tank volume or valve technology to the respective application. This keeps the system flexible without the need for major modifications to the machine design.
2. HYDRAULIC POWER UNITS IN MOBILE AND DECENTRALISED APPLICATIONS
Mobile machines often operate far away from stationary energy sources. A power unit meets this need and provides power where the machine needs it. It supplies lifting arms, lifts, supports or attachments with the necessary pressure and maintains its performance even when the environment is uneven or temperatures fluctuate slightly. In decentralised systems, it takes over the energy supply for individual work steps, thus enabling flexible locations of use. Users can move the machine more quickly and use it without being dependent on fixed connections.
QUESTIONS AND ANSWERS

processes – summarised quickly and clearly.
The intervals depend on the load, running time and environment. Systems with long shifts require more frequent oil and filter checks than machines that only run occasionally. Regularly checking the cleanliness of the oil, tank and pipes prevents damage to the pump or valve technology at an early stage.
In many cases, minor modifications can enable the system to be adapted. Additional valves, larger pumps or an increased tank volume can often be integrated effectively. It is crucial that all components are compatible and that the machine can safely handle the higher performance. WEBER-HYDRAULIK provides support with clear technical specifications.
No unit can run reliably without the right oil. The medium carries the power through the system, lubricates the moving parts and keeps the temperature within limits. If the oil remains clean and retains its original viscosity, the unit responds evenly and without vibrations. However, as soon as dirt, water or abrasion accumulate in it, wear increases noticeably. Contamination in the system can cause valves to malfunction or damage the hydraulic pump. Regularly checking the oil and oil filters and changing them when necessary will prevent system failure in the long term.
The required size is determined by the pressure, volume flow and energy requirements of the connected consumers. Anyone operating cylinders or motors with high volume flow requirements should choose a unit with a larger pump and sufficient tank volume. If higher pressures are required, a smaller hydraulic pump with a low volume flow is advantageous. Small drives, on the other hand, operate reliably at lower power ranges. It is important that the pump and valve technology are suitable for the load and that there are reserves for later expansions.
