Ejector 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.
The result of this action is a mixture of the driving and entrained (sucked) fluids, the velocity of which is reduced and the pressure increased in a second nozzle.
The practical application of this principle requires a simple apparatus which essentially consists of only 3 main parts:
Ejectors systems have a simple design, they are reliable and require low maintenance because they work without moving parts.
1= motive nozzle, 2 = diffuser, 3 = head, A = motive medium inlet connection, B = suction manifold, C = pressure manifold
Pompes à vide à jet de vapeur multi-étages en graphite pour applications corrosives.
Les éjecteurs à flux variable, qui sont fondés sur la technologie de pompe à jet éprouvée de GEA, sont souvent utilisés pour la récupération de chaleur.
Steam jet cooling systems are based on proven jet pump technology and often used to cool a liquid directly without any additional refrigerant by means of flashing into the vacuum.
Les systèmes à jet de vapeur et LRVP combinés, qui sont fondés sur la technologie éprouvée des pompes à jet, sont souvent utilisés pour créer et maintenir le vide.
