3 Things To Consider When Choosing the Right Vacuum Technology

In today’s modern manufacturing World, vacuum technology plays a critical role in just about every industry. From food packaging and plastic extrusion to chemical distillation and woodworking router tables … all of these applications, and many more, simply wouldn’t be possible without vacuum. This means that choosing the right type of vacuum pump to fit an application is extremely important for not only the efficiency of the process, but the quality of the end product. Unfortunately, it’s common to assume that generating reliable and efficient vacuum merely consists of plugging in the vacuum pump and letting it drop to the required level – so the type of vacuum technology isn’t important, right? Wrong!

Important Things To Remember When Choosing the Right Vacuum Technology for Your process

There are three key factors to remember when researching and choosing the proper vacuum pump for your process: how the vacuum pump will impact the application and vice-versa; what the application’s vacuum requirements are; and the complete cost of ownership.

1. Impact of Process on Pump & Pump on Process.

It stands to reason that the type of pump you choose will impact your application, just as your application will impact the pump! For example, if you are selecting a pump for an oil-free application, such as pharmaceuticals or food packaging, then choosing an oil-sealed pump wouldn’t be the right decision.

Pump Impact on Application Application Impact on Pump
Pump vibration Dust/debris from process
Oil emission (if an oil-sealed pump) Mechanical movements & vibrations
Noise, heat, and particle emissions Gases/other mixtures in process
Energy consumption  

2. Vacuum Level Requirements.

Different applications require different levels of vacuum, and different vacuum pumps pull different pressure levels. With this in mind, knowing which vacuum level is required is vital to selecting the right pump technology. For instance, selecting a liquid ring pump that operates only to 28-29" of vacuum would not be suitable for a process that requires good gas flow at less than 1 torr. You should also consider whether or not your vacuum pump requires a consistent pressure level to be held, or whether it’s focused more on the pump-down process.

3. Cost of Ownership.

This includes both the initial capital costs of purchasing the vacuum pump, as well as the costs of servicing and maintaining the vacuum pump over its lifetime of use. For example, certain pumps, such as a vane pump, might require more maintenance because of consistent vane replacements – while the maintenance costs on oil-sealed rotary screw pumps could be much lower. Saving energy, reducing the frequency of oil changes, and having maximum pump availability due to non-wearing points are all elements to consider when looking at pump costs.

Vacuum, the invisible force, is indispensable in industrial production facilities around the world. When an industrial application requires a clean environment or pressure below atmospheric levels, a steady supply of vacuum is needed. Our vacuum products are the starting point to providing a total vacuum solution for dedicated point-of-use machines and central vacuum systems.
