What Are the Main Types of Vacuum Pump?

When it comes to vacuum pumps, there are many different types to choose from. It’s important to select the right one for your needs, as well as the type of vacuum pump. Each type of vacuum pump is designed for a specific type of vacuum and has its own advantages and disadvantages. It’s important to choose the right pump for your project, and to factor in the price of the technology and the type of vacuum required. Armed with this knowledge, you’re ready to start shopping for the perfect vacuum pump for your needs! 

There are five main types of vacuum pump:

Rotary Vane Vacuum Pumps

If you are in the market for a high-performing vacuum pump, we recommend you consider purchasing a rotary vane vacuum pump. Rotary vane vacuum pumps are small and compact, making them perfect for use in tight spaces. They also have higher level of rough vacuum than other types of pumps, ensuring efficient removal of liquid or gas samples. While rotary vane vacuum pumps require oil to operate effectively and ensure airtightness, it is recommended to change it every 3,000 hours of operation to optimize performance. In addition to regular maintenance checks and replacements, proper lubrication will keep your pump running smoothly under all conditions.

Diaphragm Vacuum Pump

Diaphragm vacuum pumps are particularly advantageous owing to their resistance to corrosion and chemicals. This makes them ideal for use in fields such as the food industry, which is constantly subjected to various types of contamination. They are also widely used in rotary evaporation and treatment of volatile compounds. In addition, diaphragm vacuum pumps are dry pumps – this means that they do not require lubrication and maintenance costs are lower than with rotary vacuum pums.

Liquid Ring Vacuum Pump

Liquid ring vacuum pumps are an important part of industrial processing. These machines work by centrifuging a liquid in the pump chamber, which in turn results in high flow rates and improved process efficiency. These pumps are useful for different applications such as distilleries, petroleum refineries, power plants, et cetera. They can be used for vacuum filtration, moisture extraction, mineral recovery and ash handling. In addition to their utility in industrial settings, liquid ring vacuum pumps offer many advantages that may appeal to distillers and vintners alike – such as low noise levels and high-performance reliability even at high operating temperatures.

Scroll Vacuum Pump

Scroll vacuum pumps are used for clean and dry vacuum pumping. They are therefore used widely in the research field and in laboratories. Scroll vacuum pumps use two spiral-shaped scrolls to pump and compress liquid or gaseous media, making them quieter, more compact and less oil-dependent than rotary vane type vacuum pumps. Maintenance is necessary on scroll vane type pumps as seals must be replaced often to ensure optimal airtightness; however, this process can be automated using automatic sealers or robotically fitted onto the pump unit. The main disadvantage of these types of vacuum pumps is their vulnerability to debris (such as particles) that tend to erode the spiral vanes over time.

Turbomolecular Vacuum Pump

Turbomolecular vacuum pumps are excellent machines for high-pressure and high-flow applications. They can attain pressure levels of 10-12 mbar, making them suitable for a variety of industries. The flow rates vary depending on the type of gas being pumped; they typically range from 50 l/s to 5,000 l/s. 

Due to their complex technology, turbomolecular vacuum pumps are expensive to purchase and may require more maintenance than other types of vacuum pump. However, these pumps have the advantage of not using oil – an important consideration in ultrahigh vacuum applications such as analytical instrumentation or laboratory research.

How to Choose A Vacuum Pump?

When it comes to vacuum pumps, it’s important to take into account several factors in order to make the best choice for your needs. 

The first of which is the intended use of the vacuum pump. 

Secondly, you must determine the type of vacuum pump – rough vacuum, low vacuum, high vacuum or ultrahigh vacuum. 

Thirdly, you need to take into account the quality of the vacuum pump, as well as the desired vacuum level. Fourthly, you need to decide on the type of vacuum pump – rotary vane pump, diaphragm pump, positive displacement pump or impulse pump. 

Fifthly, you must consider the type of vacuum – rough vacuum, low vacuum, high vacuum or ultrahigh vacuum.

Sixthly, you must consider the number of molecules that the vacuum pump can obtain. 

Seventhly, you must decide on the price. 

Eighthly, you must decide on the warranty. 

Ninthly, you must choose a vacuum pump. 

Factors to Consider While Choosing A Vacuum Pump

When it comes to vacuum pumps, there are a lot of factors to consider. To make the right choice for your needs, here are some of the key factors to keep in mind: vacuum level, the pump’s flow rate, chemical compatibility, maintenance and cost . Once you have these factors under control, you can start narrowing down your choices to the vacuum pump that is perfect for your needs.

Vacuum level

When choosing a vacuum pump, it is important to ensure that the level of vacuum required is met. It’s important to research which type of pump will be best for your specific needs. Moreover, always keep an eye on the size and type of motor used in pumps as these factors will impact its performance.

The Pump’s Flow Rate

When it comes to vacuum pumps, it is important to understand their flow rate. This figure determines the time it will take for the pump to drain an object of a certain size, and is therefore crucial in selecting the right vacuum pump. The table below provides insights into how different types of vacuum pumps impact draining times – this can be helpful in making informed decisions when purchasing a vacuum pump. 

For high-speed pumping applications, choosing a higher flow rate will shorten draining time by decreasing surface area contact and thereby reducing heat generation.

Chemical Compatibility

When choosing a vacuum pump, it is important to take into account the compatibility of the gases used with it. In some cases, you may also need to consider using a different type of vacuum pump altogether if your application requires a specific gas combination that isn’t compatible with the one offered by your chosen device. For utmost safety during use, ensure that the vacuum pump has anti-icing and deflating features in case of emergency. 

Also, get an extended warranty if you’re not sure about its quality – after all, accidents do happen!


Vacuum pumps play an important role in scientific research and industrial applications. They are responsible for evacuating air or other vacuum-like gases, which is why it is essential to keep them lubricated. Believe it or not, a dry vacuum pump performs better than one that isn’t lubricated. Lubrication makes the pump more efficient and resistant against wear and tear. 

However, regular maintenance of the pump is still required even with a lubed system as parts can dry up over time. In lab settings where high-vacuum levels are required, using a dry vacuum pump is ideal as it eliminates the need for frequent oiling or greasing of moving parts

Maintenance and Cost

It is necessary to take into account a number of different factors of vaccum pump when calculating the maintenance and cost of an installation. These include the frequency of cycles, purchase price, as well as operating and maintenance costs. However, before arriving at a final figure, it is important to analyze each criterion in detail.

How to Choose between A Vacuum Pump without Oil and A Lubricated Vacuum Pump?

Choosing the right vacuum pump can be a daunting task. There are two types of vacuum pumps available on the market – oil-less and lubricated. The lubrication of the vacuum pump is another important factor to consider. If you’re in the market for a dry vacuum pump, which does not require oil, then you are in for a treat. These pumps are particularly recommended for use in the agri-food industry, as they are highly efficient and require little maintenance. 

On the other hand, if you’re looking for a lubricated vacuum pump, then you’ll need to keep in mind that it requires regular maintenance – approximately every 12 hours. Make sure to consult with a qualified technician to find the right vacuum pump for your needs.

What Are the Main Uses for Vacuum Pumps?

When it comes to vacuum pumps, there are many different types and uses for them. If you are in the market for one, it is important to know what those uses are in order to make an informed decision. Mainly, vacuum pumps are used in different areas of research and industry, such as laboratories, the medical and pharmaceutical industries, filtration and mass spectrometry, drying, vacuum metallurgy, vacuum mixing and beam welding. 

However, if your application concerns the agricultural or food-processing industries, we recommend that you purchase a rough vacuum pump. These pumps are specifically designed to handle high-vacuum environments. If you work in surface state physics or particle acceleration, we recommend an ultrahigh vacuum pump.
