With state-of-the-art pilot plants and test benches our R & D Center is optimally equipped for testing in the fields of jet pumps and vacuum systems.

The basic principle of jet pumps consists in the liquid or gas jet being emitted by a nozzle at high speed entraining and accelerating the surrounding liquid, gas or solid matter.

Variable - Flow Ejectors are based on proven GEA jet pump technology and often used for heat recovery.
