Designers and Manufacturers of Industrial Jet Apparatus

‘Jet-Apparatus’ is a term typically used to identify a piece of equipment (Liqui-Jet Eductors, Line-Type Heaters, Exhausters, Gas & Chemical Infusers, Mixing Eductors, and Gas-Jet Ejectors, Exhausters, Siphons, Solids Eductors and Steam Spargers that uses a fluid under pressure (liquid / gas / vapor), to perform work on, and in direct contact with, another medium (liquid / gas / vapor / granular solid), in a defined, predictable way.

The main principle governing the operation of typical Jet-Apparatus is Conservation of Momentum. When fluid pressure (potential energy) is converted into fluid velocity (kinetic energy) by means of a constricting orifice (i.e. Converging Nozzle), there exists an associated useful pressure drop. For a constant primary fluid mass flowrate and constricting orifice, this pressure drop is a function of the primary fluid pressure. Jet Apparatus uses this pressure drop to entrain a secondary medium (fluid or granular solid), within a chamber (i.e. Suction Chamber) that is at the pressure of the secondary medium, for the purpose of pumping, mixing, evacuating, etc. The suction capacity of a specific device is typically a function of the primary fluid velocity and mass flowrate [as well as properties of the suction material and downstream pressure]. Once entrained, the velocity of the mixture of primary and secondary media (kinetic energy), is converted back into pressure energy (potential), by means of a volumetric divergence (i.e. Diffuser). Available discharge pressure is typically a function of the diffuser velocity and total mass flowrate. The three main components of Jet-Apparatus (Converging Nozzle, Suction Chamber, Diffuser), are rigidly fixed in specific relation to each other, hence there are no moving parts – one of the main advantages of this type of device.
