Considerations for Choosing the Right Vacuum Pump

Vacuum tables are used in many commercial and industrial processes to hold down a wide variety of items during additional processes.  The type of vacuum pump you choose for your table depends upon many factors, including the type of part or substrate, and several other considerations.  It is helpful to have an understanding of the technology behind the force in vacuum tables when choosing the right type of vacuum pump.  

Many people think that an increased horsepower in vacuum force is better, no matter what.  An increase in horsepower will not necessarily yield a better process, but it will increase your electric bill for sure.  The question is, just how much vacuum force do you need for your process? 

One important consideration when designing your vacuum system is the surface area of your part and the table.  Large parts such as sheets of aluminum or metal would not require as much vacuum as smaller or odd shaped parts.   Small parts require stronger vacuum force to securely hold your part in place.  The contact surface area between the vacuum holes and the object is a key consideration. 

The friction between your vacuum table surface and the substrate is of important consideration when choosing the proper vacuum pump.  A slippery table surface will allow your part or substrate to move regardless of the vacuum force, whereas a non-slippery surface should hold your part firmly in place with adequate vacuum force applied. 

Air permeability of your object is another very important factor that directly affects the amount of vacuum force needed.  Canvas or paper products with greater air permeability will require more vacuum force than a sheet of metal.
