A vacuum ejector, or simply ejector 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.
Jet noise may be reduced by adding features to the exit of the nozzle which increase the surface area of the cylindrical jet. Commercial turbojets and early by-pass engines typically split the jet into multiple lobes. Modern high by-pass turbofans have triangular serrations, called chevrons, which protrude slightly into the propelling jet.
The S type pump is useful for removing water from a well or container. Shallow well pumps are those in which the jet assembly is attached directly to the main pump and are limited to a depth of approximately 5-8m to prevent cavitation. Deep well pumps are those in which the jet is located at the bottom of the well. The maximum depth for deep ...
The young enterprise produced injectors and jet-pumps as well as the associated condensers. In 1874 the small factory was already supplying 2,000 devices. The enterprise grew quickly, and in a few years established proxies in Germany and neighboring European lands (London, Paris, Milan , Genoa, Barcelona, Breslau (Wrocław), St. Petersburg ...

An oil diffusion pump is used to achieve higher vacuum (lower pressure) than is possible by use of positive displacement pumps alone. Although its use has been mainly associated within the high-vacuum range, down to 1 × 10 −9 mbar (1 × 10 −7 Pa), diffusion pumps today can produce pressures approaching 1 × 10 −10 mbar (1 × 10 −8 Pa) when properly used with modern fluids and accessories.
