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.
1= motive nozzle, 2 = diffuser, 3 = head, A = motive medium inlet connection, B = suction manifold, C = pressure manifold
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, also known as jet pumps, have a simple design, they are reliable and require low maintenance because they work without moving parts.
Multi-stage steam jet vacuum pumps in graphite for corrosive applications.
Variable - Flow Ejectors are based on proven GEA jet pump technology and often used for heat recovery.
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.
Combined Steam Jet and LRVP Systems are based on proven jet pump technology and often used to create and maintain the vacuum.
