or superheated).
* The driving steam travels through the driving nozzle, which has a Laval-shaped contour to generate supersonic speed by converting the steam pressure to kinetic energy and the corresponding low pressure at the outlet.
* At this part of the pump any kind of vapour or gas is entrained, intensively
mixed with the driving medium and accelerated in the mixing nozzle. The velocity of the mixed flow is firstly reduced by a shockwave and further on in the outlet cone after the throat of the mixing nozzle to the required counterpressure and the kinetic energy is reconverted to pressure energy.
