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.
A large vacuum chamber. A small vacuum chamber for studio or lab use in de-airing materials such as mold rubbers and resins. Vacuum chamber for testing leaks in packaging. A vacuum chamber is a rigid enclosure from which air and other gases are removed by a vacuum pump.
The turbomolecular pump can be a very versatile pump. It can generate many degrees of vacuum from intermediate vacuum (≈10 −2 Pa) up to ultra-high vacuum levels (≈10 −8 Pa). Multiple turbomolecular pumps in a lab or manufacturing-plant can be connected by tubes to a small backing pump.
In the field of oil regeneration and re-refining, vacuum pumps create a low vacuum for oil dehydration and a high vacuum for oil purification. [44] A vacuum may be used to power, or provide assistance to mechanical devices. In hybrid and diesel engine motor vehicles, a pump fitted on the engine (usually on the camshaft) is used to produce a vacuum.

[1] The company is noted in Die Deutsche Wirtschaft database as being foreign-owned by a parent company, Allied Motion Technologies, based in the United States of America, and serves a global market.
The sorption pump is a vacuum pump that creates a vacuum by adsorbing molecules on a very porous material like molecular sieve which is cooled by a cryogen, typically liquid nitrogen. The ultimate pressure is about 10 −2 mbar. With special techniques this can be lowered till 10 −7 mbar.
