Leading Small Vacuum Pump Manufacturers

Types of Small Vacuum Pumps

Like all other types of vacuum pumps, manufacturers can set up small ones using one of three configurations: positive displacement, momentum transfer, or entrapment.

Positive Displacement in Small Vacuum Pumps

Positive displacement operates under the premise a vacuum can be partially created by increasing a container's volume. By constantly closing off, exhausting, and re-expanding one of their compartments, positive displacement vacuum pumps can continuously empty chambers without requiring infinite growth. Diaphragm pumps, rotary vane pumps, piston pumps, screw pumps, external vane pumps, toepler pumps, and lobe pumps are a few examples of tiny positive displacement pumps.

Momentum Transfer in Small Vacuum Pumps

Momentum transfer in small vacuum pumps drives gathered gas molecules to accelerate in one direction. They accomplish this by repeatedly slamming onto a hard surface or a steam jet. Turbomolecular pumps and diffusion pumps are two types of tiny momentum transfer pumps.

Entrapment in Small Vacuum Pumps

Tiny vacuum pumps designed for entrapment work will rapidly cool and heat to produce condensation. This will compress and trap gas molecules in either an absorbing or solid form. Ion pumps, cryopumps, sorption pumps, non-reactive getter pumps, and titanium sublimation pumps are a few examples of small entrapment pumps.

Oilless Vacuum Pump

Small vacuum pumps can be made wet, dry, or oilless. Oil or other liquids must seal and lubricate inside wet vacuum pumps. Oilless vacuum pumps are used in situations where precise control is needed. Oilless pumps do not produce as strong of a seal as those that utilize oil or another liquid. Thus they take less time and money to clean. Wet pumps also produce lower enclosure pressures than dry vacuum pumps. However, they are expensive because they require equipment to prevent oil backstreaming.

Liquid Ring Pumps

Liquid ring pumps can be used as gas compressors and vacuum pumps. In a liquid-ring pump, a spinning ring of liquid is stirred to create the compression-chamber seal. The rotor is the only moving component, making them low-friction designs. The shaft seals are the only points of sliding friction. An induction motor is used to power liquid-ring pumps.

Applications of small vacuum pumps

Small vacuum pumps can be portable and used as emergency supplies in high-risk locations like nursing homes, public swimming pools, and ambulances. Additionally, they provide suction for use during surgical and dental operations. Portable pumps frequently have an extra layer of metal or plastic on top for visual appeal.

Miniature vacuum pumps are available for even smaller applications when a battery-powered device is needed. In several fields of science and research, they are used for complex, delicate applications like particle counting and particle sizing. Small vacuum pumps can be tucked away into workspace areas that won't obstruct operations. Some have housings that are created expressly to fit in small locations.

Choosing the Proper Small Vacuum Pump Manufacturer

To make sure you have the most productive outcome when purchasing small vacuum pumps from a small vacuum pump manufacturer, it is important to compare at least 4 manufacturers using our small vacuum pump directory. Each small vacuum pump manufacturer has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the manufacturer for more information or request a quote. Review each small vacuum pump business website using our proprietary website previewer to get an idea of what each business specializes in, and then use our simple RFQ form to contact multiple small vacuum pump businesses with the same message.
