Ejector Systems
Ejectors
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
Functional principle
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:
- motive nozzle
- diffuser
- head
Ejectors, also known as jet pumps, have a simple design, they are reliable and require low maintenance because they work without moving parts.
