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:

  1. motive nozzle
  2. diffuser
  3. head

Ejectors systems have a simple design, they are reliable and require low maintenance because they work without moving parts.
