Druckerzeuger

Druckerzeuger is a general term for devices that generate and deliver fluid pressure in a closed system. They convert energy from an external source—such as electricity, fuel, or stored chemical energy—into hydraulic or pneumatic pressure used to actuate machinery, perform tests, or enable precise control in industrial and laboratory settings. The concept covers a wide range of equipment from compact laboratory pumps to large industrial compressors and hydraulic power units.

Two broad classes are common. Pneumatic Druckerzeuger generate pressure of gases, typically air, using compressors, screw or piston machines, or gas cylinders with regulators. Hydraulic Druckerzeuger produce liquid pressure through hydraulic pumps, with options such as fixed or variable displacement pumps, accumulators for energy storage, and pressure intensifiers. Both types may include control systems, filtration, heat exchange, valves, sensors, and safety devices.

Key specifications include maximum pressure (Pmax), controllable pressure range, flow rate or volume per unit time, regulation accuracy, response time, energy efficiency, and physical footprint. Design considerations also address durability, ambient conditions, maintenance needs, and safety requirements. Overpressure protection, relief valves, proper sealing, and compliance with relevant standards are essential.

Typical applications span manufacturing automation, material testing and calibration, leak testing, process control, and research laboratories. Druckerzeuger enable precise actuation of cylinders, valves, and tools, and they form a core component of pneumatic and hydraulic power systems.
