How To Select The Right Vacuum Pump?


If you are wondering what type of vacuum pump will be compatible with your other appliances and how it will fit in with your existing system then it is about time that you explore the various options available. Your options depend on the different displacement capacities provided and of course the ultimate vacuum levels. The basic 4 types of vacuum pumps are mentioned as below.

1) Rotary Vane

A traditional rotary vane vacuum pump is a preferred choice for many given its low cost installation and operating costs too. This pump makes use of oil for lubricating the parts, achieving a tight seal, and removing the heat from components in order cool down the rotors. One thing to keep in mind is that the oil here needs to be changed on a regular basis.

2) Diaphragm

This type of vacuum pump operates on the pulsing motion that opens and closes valves in order to move air, a type of dry pump. The reason this design is preferred is that it eliminates the usage of oil. Also, as the pumps are made of non-corrosive material like polytetrafluoroethylene, it makes them less susceptible to any type of damage caused by the vapors. The ultimate vacuum levels of this pump are not very deep and also the displacement capacity is quite lower as compared to others.

3) Scroll

These are dry pumps that make use of two spiral scrolls for the process of compressing air and vapor, which moves towards the exhaust in the circulation process. The lifetime operation costs for these pumps are much lower as compared to the initial high up-front costs. These pumps do not require oil and also the level of maintenance required is low which makes them a fairly suitable selection.

4) Hybrid Pumps

These are a combination of the traditional rotary vane and the diaphragm. Here the diaphragm pump works in a manner to reduce the vapors going through the RV pump by pumping the oil and thereby condensing the oil. This particular set-up helps the oil remain cleaner and thereby reduces the frequency in which oil needs to be changed.

We have covered all the major types of vacuum pumps and have also given a brief about their usage too. For expert help and advice you can contact vacuum pumps and find the pump that suits your needs and requirements.
