Hydraulic circuits are designed according to their task and their area of application. Designing hydraulic circuits requires knowledge of flow behaviour and pressure losses in valves and fittings, as well as characteristics of the pump. A hydraulic circuit can be compared to an electrical circuit. This analogy can be made evident in the experimental unit.
The experimental unit includes a centrifugal pump, a rotameter, a diaphragm valve, a water tank and various other valves and fittings. After filling the system once the experimental unit can be operated independently from the water supply.
