What You Should Know About Vacuum Pumps

Vacuum pumps are devices which use a variety of methods to remove air and gas particles from an enclosed container. This can help create a vacuum needed to manufacture electronics, to freeze dry food items and even to safely package some materials. Before you purchase a pump, it is a good idea to know what types there are as well as what they are used for so you can be sure to get the right one for your needs.

What Types Are There?

Not only are there different makes and models of pumps, there are different types as well. You can find busch vacuum pumps for almost any purpose which run by positive displacement, momentum transfer or entrapment. With positive displacement pumps, you are expanding a compartment, sealing it off and then exhausting it. A momentum transfer pump works by moving sections transferring momentum to the particles along a directed path, effectively pushing them out. This is often seen working in conjunction with a positive displacement pump. An entrapment pump can use cold temperatures to condense the gas, chemicals which can form solids with and around the gas particles, or electrical fields to ionize particles and attract them out of the space.

What Are They Used For?

There are a couple of places in your home where vacuum pumps can be used as well as many industrial applications. You are most likely to encounter home vacuum pumps in food preparation and storage such as freeze dryers and home units designed to seal food into a vacuumed plastic bag. This can help keep harmful bacteria from growing on and spoiling your food items before you can eat them because those bacteria need air to flourish.

Vacuum pumps can be used all over your home or worksite to preserve food, manufacture electronics and much more. To find the right one for your needs you will need to consider the type of pump and the application.
