Liquid jet vacuum pumps with threaded connections are mainly used in chemical laboratories for the production of vacuum, for example in vacuum distillation or drying. They are also used for evacuating syphon lines, suction lines of circulating pumps and condensers; for deaeration of pressure vessels and for producing negative pressure in Nutsch ...

A vacuum ejector, or simply ejector, or aspirator, is a type of vacuum pump, which produces vacuum by means of the Venturi effect. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.

The simplest and cheapest vacuum pumps are water jet pumps. As in a vapor pump (see Fig. 2.46 or 2.51), the liquid stream is first released from a nozzle and then, because of turbulence, mixes with the pumped gas in the mixing chamber.

Water ejectors are vacuum pumps, driven by a high pressure water (or similar medium) or steam. They use kinetic energy of the driving medium to suck in gases, vapours or other liquids and then discharge the resultant mixture against a counter pressure.

High performance water jet pumps are useful for generating a vacuum and evacuating liquids and vapours from containers. These devices provide the constant final pressure required for common procedures.

Fox Liquid Eductors are venturi jet pumps that use liquid to create vacuum to mix, blend, or dilute other liquids, dry solids, or gasses into a liquid stream. They are used to replace or eliminate pumps when simple, ultra-reliable liquid mixing is required.

Liquid jet vacuum ejectors suck off gases and/or vapours from a process. The lowest possible suction pressure in the reactor is only limited by the vapour pressure of the motive liquid. It is possible to compress to atmospheric or even higher pressure.

It is characterized by simple structure, reliable performance, low-level installation, convenient operation and maintenance; and the pump has the advantages of large pumping capacity, no requirement for the pumped medium, and quick vacuum formation.
