Jet Mixer Systems

Applications. Liquid jet mixers are jet pumps to mix and circulate liquids. The range of applications for liquid jet mixers is only limited by the viscosity of the liquid to be mixed. As a rule, jet mixers can be used in all cases where the liquid to be mixed can still be supplied by a centrifugal pump. Liquid jet mixers are mainly used in vessels, storage tanks and neutralization basins.

Jet Pumps, Mixers, Heaters and Vacuum Systems

Jet pumps, also referred to as ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids in which a gaseous or liquid medium serves as the motive force. They operate by the conversion of pressure energy into velocity in suitable nozzles. They are “pumps without moving parts”. 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, ...
