These pumps may also be mounted on wheels or in cabinets so they can be easily moved when necessary.

Medical vacuum pump tubing and gaskets are made out of strong plastic and rubber that can withstand extreme conditions without boiling or releasing harmful gasses.

One of the most common uses for medical vacuum pumps is for the provision of suction during surgical procedures. Pneumatic air supply, gas chromatography, air quality samplers and analyzers rely on vacuum pumps as well. Simple vacuum pumps called aspirators remove excess fluids through a tube system. Aspirators are important vacuum pumps because they provide fast and easy suction almost anywhere.

Medical vacuum pumps vary in their configuration depending on a number of factors. Aspirators, for example, are basic, non-mechanical devices that generate a vacuum through the Venturi Effect, which is the reduction of pressure in an enclosure that occurs when a fluid flows through a constricted section of that enclosure (in this case a pipe or tube).

Other vacuum pumps can be more complicated. There are three main kinds of mechanical vacuum pumps: positive displacement, momentum transfer and entrapment pumps, though within those categories there are subcategories. Many medical vacuum pumps are positive displacement pumps that are also rotary vane pumps. Diaphragm pumps are another variety of positive displacement pump.

Momentum transfer pumps work by causing gas molecules to accelerate in a consistent direction through repeated collisions with a solid surface or steam jet. Entrapment pumps use rapid heating and cooling to cause condensation, which in turn traps molecules in a solid or absorbed state.

All vacuum pumps can also be identified as wet or dry. Oil-lubricated pumps and liquid ring vacuum pumps both involve a liquid at some point in their processes. Dry vacuum pumps don't make use of any liquid and are more suitable in healthcare contexts.

Lubricant oil could, if used in a medical vacuum pump, enter pump air streams and contaminate workspaces or harm patients. For this reason, almost every medical vacuum pump is oilless.
