Vacuum pumps

Various models of vacuum pump for sale at Foeth

Vacuum pumps create a partial vacuum by removing air particles or gas molecules from a sealed volume. A vacuum pump changes the pressure of the sealed volume by lowering it below the atmospheric pressure. Its applications range from medical and pharmaceutical industries to filtration and mass spectrometry. Every industry requires a unique type of vacuum pump. Foeth provides a collection of vacuum pumps suitable for various applications that require filtration or vacuum metallurgy. There is also a selection of pumps at discounted prices. Besides, the used vacuum pumps are in perfect operating conditions due to the checks run before they are released for sale.

Order high-quality vacuum pumps from Foeth.

What are the types of industrial vacuum pumps?

The primary function of a vacuum pump is to change the pressure in a contained space and create a vacuum by pushing molecules out of a confined volume. As the pump removes molecules from the sealed volume, it becomes hard to remove additional molecules. The vacuum power required ranges from a low to an extremely high vacuum. Most vacuum pumps are classified based on the pressure range they can achieve, leading to three groupings of pumps; primary, booster and high vacuum pumps. Industrial vacuum pumps are wet or dry. Wet pumps have lubricants like oil or water, while dry pumps don’t have fluids in the rotating mechanisms or static parts. Some of the working principles of vacuum pumps depend on the type. For instance, capture pumps don’t have moving parts and can create high vacuum pressures using cryopumps or sputter ion pumps. Transfer pumps use kinetic energy or positive displacement to push gas molecules from a sealed volume.

How to Select the Best Vacuum Pump

You can choose a vacuum pump for your industrial processes based on various factors. When the vacuum pump is adopted for your applications, you can determine the vacuum level and technology used for air transfer and lubrication. The vacuum pump should generate the desired vacuum level depending on the scarcity of molecules. When the pressure of residual gases is weak, the gas has fewer molecules, improving the vacuum quality. Lubrication is important since lubricated vacuums have greater efficiency and resistance, while a dry vacuum pump is ideal for laboratory environments. The flow rate usually varies depending on the model and vacuum pump manufacturers. Hence, it is important to evaluate the capacity of the Busch vacuum pump and its pumping speed.
