Vacuum pumps common types and applications

Vacuum pump type

Vacuum pumps are used in a variety of process equipment and to pump air, water vapor, organic and inorganic solvents and acids. In order to meet the special needs of transporting various gases, there are now many different types of vacuum pumps on the market.

Liquid ring:

Liquid ring vacuum pumps are used for medium to heavy steam load conditions. Liquid sealants are used to run vacuum co. LTD about 30 pumps. Low vacuum obtained with the use of oil, glycol or other low vapor pressure fluids. This type of pump is desirable because it can be sealed by a fluid with a process of gas/vapor that would damage other types of pump (i.e., oil seals) and is relatively inexpensive. High reliability because of its simplicity.

Rotating blade:

Rotary vacuum pump is used for pumping clean, dry, no active gas oil seal pump. The actual limit due to oil as its sealant/lubricant is about 5 MMHG of vacuum. These pumps are usually air-cooled and directly drive 1750 rotary pumps, which cover a small area and save space. Reliability is average periodic oil changes and periodic blade/filter changes to maintain maximum time. Pricing is very moderate due to the vacuum they produce.

Rotating piston:

Slide valve vacuum pump is industrial – grade heavy – duty pump produced in 50-1 tank vacuum. The use of these pumps, which are highly polluting, must be handled by pumps. Reliability is the medium height abuse these pumps suffer from. The price reflects the high vacuum performance of these pumps and their ability to handle a large number of contaminants.

Dry vacuum pump:

Dry vacuum pump, compressed gas without sealing fluid such as oil or water to aid. They are used in extremely corrosive applications where pump failure will occur, or where environmental problems exist. The vacuum ranges from the atmosphere to 10 MMHG. The design includes screws, leaves and claws.

There are many types of vacuum pump, vacuum pump applications are also extremely wide. To this end, the vacuum pump manufacturers have collected a relatively complete collection of common vacuum pump applications to share with you. If you have more types of vacuum pump applications, also welcome to supplement!
