About hydraulic power units
Coupling Hansa Flex HK A3845 42 N3 AL is a hydraulic power unit or one of its assemblies: tank, pump group, control valves, filtration and monitoring.
Typical power unit composition
| Assembly | Function |
|---|---|
| Tank | Oil storage, cooling, contaminant settling |
| Pump group | Generates flow and pressure |
| Control valves | Controls the consumers |
| Filtration | Maintains oil cleanliness |
| Monitoring | Pressure gauges, level and temperature sensors |
What matters when ordering
- Flow and pressure — the base parameters for pump selection.
- Tank volume — typically 2–4 minutes of pump output.
- Duty cycle — continuous or intermittent; this determines cooling.
- Operating conditions — ambient temperature, contamination, climate.
We build power units for a specific task, or supply individual assemblies for repair and assembly.
