A Guide to the Different Types of Vacuum Pumps

An ideal way to achieve a vacuum in most industrial and research applications is by using vacuum pumps. They tend to be highly available in different types as well as easier support and installation thereby meeting ones needs effectively. The need to upgrade the pumps on one’s machine calls for learning the different types of vacuum pumps. This is because it helps greatly when one is in need of making the right choice of the available different pumps types. This also prepares one for any further research should you ever need to replace or even repair your pump. In this case one gets to have a better understanding of their machine and how it works. It’s crucial to invest in the right types of vacuum pumps for one’s application given that this gives one year’s of reliable performance. Below is a guide on the different types of vacuum pumps.

One of these types is rotary vane pumps. Its very popular in a variety of scientific and industrial applications.It uses an oil-filed chamber with a rotating rotor and spring-loaded varying slide inside the rotors slots. There is the creation of pockets of trapped air on the vane sides which is brought about by the rotor turning followed by the vanes. Once the number of vanes and their length is increased it increases the size of the trapped pockets as well as the amount of air they can hold resulting to a higher vacuum rate.

Next is drag pumps. Its best for applications with high pumping speed. The pumps uses a combination of surface area and velocity to generate a vacuum and this come from the motion of the impeller blades. This results to the creation of a drag chosen on the gas molecules in the pump. They are therefore ideal for aerial operations due to their high reliability and efficiency.

Next is diffusion pump. These types of vacuum pumps are highly used in electron microscopes and a variety of other scientific applications. There is no reliance on mechanical parts here as they use high-speed jets of vaporized oil. It’s the best available vacuum pump at moderate cost therefore an excellent choice for those looking to find a new vacuum pump. Such vacuum pump types are highly used due to the quiet operation and excellent pumping speeds.

The last one is dry pumps. They are highly used in manufacturing processes that need a certain atmospheric pressure as they are used to create a vacuum in a system. Air is sucked from the system using a rotary vane mechanism. They are lubricated lowering the need be periodically lubricated with oil hence best for people who want to find a new vacuum pump. The need to find a new vacuum pump makes one with cost and time saving the best preferred. There is reduced risk of contamination since they tend to be less likely to leaking contaminants than oil-lubricated vacuum pumps.
