Small Vacuum Pumps Small vacuum pumps are devices used to create a vacuum within a sealed area. They are smaller than most other industrial vacuum pumps in terms of size and dimensions but are otherwise similar.

Small vacuum pumps are used to generate suction for use in surgical and dental procedures, and portable pumps can be found on ambulances or among emergency supplies for high-risk areas like pools and nursing homes.

Miniature vacuum pumps can be used for battery powered applications, and some branches of research and science use them for particle sizing and particle counting. Small vacuums can be designed to accommodate a range of spaces and uses.

Some of them are portable, and some are designed with housing that can fit in tight spaces or in places where they won't interfere with people working nearby. Like all other varieties of vacuum pumps, most small vacuum pumps are made of stainless steel or aluminum because of the material's durability and resistance to contamination.

Portable pumps often feature an extra plastic or metal outer layer to enhance their appearance.

A small vacuum pump's effectiveness does not necessary correlate to its size. They can be configured in any one of the three ways in which all other vacuum pump varieties are configured: positive displacement, momentum transfer and entrapment.

Small pumps are commonly diaphragm pumps, which use positive displacement to create a vacuum. Momentum transfer pumps work by causing collected gas molecules to accelerate in a consistent direction through repeated collisions with a solid surface or steam jet. Entrapment pumps use condensation created by rapid heating and cooling to compress and trap gas molecules in a solid or absorbed state.

Small vacuum pumps can be wet or dry, which means that they can function without the use of any liquid, or they can use oil (or other liquids) for lubrication or sealant. Oilless vacuum pumps are cleaner because there is no oil that can enter the vacuum and contaminate it.

Dry vacuum pumps rely on close internal dimensional tolerance to create a vacuum instead of a fluid seal. Oil-less pumps are frequently used when operating conditions must be closely controlled.

Wet pumps are more expensive because they require additional machinery to prevent oil back streaming. However, the seal strength that is possible using oil or other liquids is much greater than that of dry pumps. This means that wet vacuums can achieve much lower enclosure pressures than dry vacuums.
