Inside A Vacuum Diffusion Pump - ChemAssociates

A vacuum diffusion pump cannot begin its work with full atmospheric pressure inside the chamber. Instead, an ancillary mechanical roughing pump (or forepump), capable of a modest level of pumping, first brings the pressure inside the vacuum diffusion chamber down to about 10-3...<<more>>

Pump Theory - Principles

All pumps use basic forces of nature to move a liquid. As the moving pump part (impeller, vane, piston diaphragm,etc.) begins to move, air is pushed out of the way. The movement of air creates a partial vacuum (low pressure) which can be filled up by more air, or in the case of water pumps, water....<<more>>

Diffusion pump - Revolvy

The oil diffusion pump is operated with an oil of low vapor pressure. The high speed jet is generated by boiling the fluid and directing the vapor through a jet assembly. Note that the oil is gaseous when entering the nozzles. Within the nozzles, the flow changes from laminar, to supersonic and ...<<more>>

Diffusion pump - Wikipedia

The steam ejector is a popular form of diffusion pump for vacuum distillation and freeze-drying. A jet of steam entrains the vapour that must be removed from the vacuum chamber. A jet of steam entrains the vapour that must be removed from the vacuum chamber....<<more>>

Working under Pressure - Milwaukee Area Technical College

The easiest method of creating a vacuum is with a transfer pump (shown in the animation below). An impeller forces gas molecules out an exhaust valve. This creates a local vacuum behind the impeller which is filled in by some of the remaining gas molecules in the chamber....<<more>>
