Vacuum pumps work by moving gas molecules from one region to the next, creating a vacuum by switching between high and low-pressure states, creating an ideal atmosphere.
These devices are widely used across both industrial and scientific processes such as composite plastic molding, flight instruments, production of vacuum tubes/lamps production as well as semiconductor processing/dry etch/photolithography processes.
They create a vacuum
Vacuum pumps can be divided into two broad categories, dry (oil-less) and wet (oil-lubricated).
Oil-lubricated vacuum ones tend to be less susceptible to corrosion while providing improved lubrication compared to their dry counterparts; however, they require regular servicing and maintenance and may be more expensive overall. You can find out more about corrosion by clicking the link.
Choosing a device for your needs depends on your application needs and desired maximum pressure range, and selecting one can be a complex process.
First you must determine your working vacuum level by using handbook formulas, theoretical data, catalog information or performance curves on prototype systems to calculate system capacity – then compare this number against commercial pumps’ maximum ratings to find an ideal match.
Mechanical devices are popularly used for low and medium applications, using compression-expansion principles to reduce gas volume within a working chamber through rotary displacement. They’re particularly well-suited for chemical, industrial and coating uses as well as freeze drying applications.
They are used in mining
Mining is a worldwide industry. This is one reason why it is important to know that industrial vacuum pumps can help miners accelerate the work. This can make the process safer for all involved.
When selecting a device for mining operations, several factors must be taken into account when selecting one. For instance, its desired level of vacuum and required flow rate must meet specific needs of underground mining operations in order to be effective.
Positive displacement, rotary vane and diaphragm pumps are among the most widely used types.
These pumps convert potential energy into mechanical rotational energy by expanding a cavity before exhausting it, with positive displacement pumps being particularly well suited to harsh environments as they’re less susceptible to oil contamination.

Rotary vane and diaphragm pumps are popular choices because they’re reliable enough to resist corrosion and stand up to abrasive applications.
They are used in laboratories
Vacuum pumps are an essential tool in laboratories, used to create low pressure environments within closed systems.
There are various types of these devices on the market with unique advantages and drawbacks that should help you select one suitable for your lab application. By understanding their operation you can make the best possible choice.
There are two primary methods for creating partial vacuum: gas transfer and entrapment.
Gas transfer ones draw in and eject gases through check or non-return valves, either positively displace them through positive displacement, momentum transfer, or both. Entrapment works by capturing gases by various means such as condensation, sublimation, adsorption or ionization – often employed for applications like mass spectrometry (MS).
Laboratory versions of these devices come in various sizes and capacities.
From stand-alone units similar to domestic refrigerators to fully integrated MS units, these devices serve many tasks, from aspiration and filtering to controlling or inducing solvent evaporation in concentrators, gel driers, ovens and rotary evaporators; they’re even useful in reducing sample vapor pressure.
They use either diaphragms or oil sealed rotary vane pumps; combination options may be available. Noise levels for laboratory devices range between 50 dB and approximately 68 dB depending on their model, while their net weight ranges from 4-14 kg.
They are used in industry
Vacuum pumps are indispensable tools in many industrial settings, changing atmospheric pressure by moving gas molecules from high to low areas.
Atmospheric pressure varies with temperature, humidity and altitude as well as fluctuations in Earth’s gravitational pull which in turn determines how quickly these devices operate. In contrast to compressors which compress air to create power for pneumatic tools and devices, they simply transport gases from one location to the other.
There are various kinds of these devices, each designed for specific uses. Positive displacement pumps produce rough or low vacuum levels while higher and ultrahigh levels can be reached using momentum transfer or entrapment pumps. Lubrication systems can further influence their performance.
Food industry vacuum pumps can be used for various tasks, including degassing and drying meat and fish products, as well as extracting entrails from packaged meat products for improved product quality, sanitation, and operational productivity.
Vacuum pumps have long been used by the pharmaceutical industry to stabilize vaccines and other medical drugs, while being employed in plastics production to remove air, adhesives and humidity from melted plastic, thus maintaining its impermeability and adhesion qualities.
There are many real-world applications for these important industrial toold. Finding the right one for you involves seeking out specialized tools from competent professionals that are just right for your needs.
