Steam jet vacuum pump - 10 - 2 000 000 m³/h
Jet vacuum pumps are used to create and maintain the vacuum in evaporators, driers, in distillation and rectification plants, and in the processes of freeze drying, poly -condensation, degassing and deodorizing.These sorts of equipment fundamentally consist of jet pumps and condensers or of a combination with other vacuum pumps such as, e.g. liquid ring vacuum pumps.
Jet pumps use the expansion work of a motive medium to create the vacuum. A high-velocity jet is generated in the motive nozzle; at low suction pressure, this jet entrains the suction medium and accelerates its path. Through transformation of the kinetic energy, this mixture is brought up to a higher pressure level in the throat and the diffuser of the ejector.
