Liquid Jet Pumps for Pumping and Combining Fluids


Transvac has supplied thousands of Ejectors to the process, chemical, food and pharmaceutical industries. Using liquid as the motive force Transvac Jet Pumps can accurately entrain, mix and dilute a secondary liquid, eliminating the need for mechanical dosing pumps and mixers.

Liquid Jet Pumps can also entrain solids that have been fluidised to enable smooth flow.

In operation a high velocity jet of pressurised liquid discharged from the motive nozzle produces a region of low pressure in the suction chamber that entrains the secondary liquid or fluidised solids.. The two streams then thoroughly mix in the throat before the resulting mixture flows through the diverging cone to regain some pressure in order to overcome system discharge heads.
