How Do I Choose the Best Vacuum Pump?

A vacuum pump is a device designed to eliminate gas molecules from a sealed environment to prevent possible damages. It therefore leaves behind a vacuum, which is of course why a vacuum pump is called what it is. With many vacuum pumps on the market, you’ll want to decide the exact type you want for your given area of application. While there are many different types, this guide will focus specifically on rotary vane vacuum pumps, as they are the most common and the most relevant to today’s consumer.
  • Rotary vane vacuum pumps are positive displacement pumps. You can use these vacuum pumps in low-pressure to high-pressure application areas. High-pressure application areas include use in automobiles as power-steering, supercharging and automatic transmissions. Espresso coffee machines and soft-drink dispensers make up mid-range pressure applications of these pumps.
  • Chemical vapor deposition systems and auto exhaust emission control systems make up low-pressure application areas for these pumps. They are also used in air conditioners, freezers and refrigerators at home to help evacuate refrigerant lines. Whichever application you want the best vacuum pump for, this guide will help you find one that fits your budget and meets your application needs.
When we did our research, we came across more than five reputable brand options. If you need a high-powered vacuum pump, you might want to consider something like the CPS 6CFM 2-Stage Vacuum Pump, or if you need one for even larger applications, the Yellow Jacket 8CFM Superevac is another great option. These options have a higher flow rate than the ones featured on this review because they are only required if you’re a professional working in a commercial setting.
The type of vacuum pump, materials used, features, capacity, size, area of application and brand will all influence the price you have to pay for any given pump. Although you’ll find most low-end vacuum pumps in the price range of $20 to $500, mid-range electric pumps and venture generators cost anything between $200 and $1000, and high-end vacuum pumps cost as much as $5000.

The more reasonably priced vacuum pumps are pocket-friendly and usually come with low capacity for small-scale application at home. With the right budget, you’ll find your vacuum pump of choice. One word of caution though, if you do decide to go with a cheap vacuum pump, make sure that you choose one that still has good safety features and solid construction. The last thing you want to do is end up with one that you will have to quickly replace; or worse yet end up with one that poses a fire hazard.
When shopping for a rotary vane vacuum pump, there are many factors you need to consider. With various features in a typical vacuum pump, you need to know the most basic and important ones with regards to your area of application.

Two of the most important features that you want to look for flow rate which is measured in cubic feet per minute (CFM) and air pressure, measured in pounds per square inch (PSI). Some other important features to look out for in a vacuum pump include:
  • Type
  • Size
  • Material
  • Color finish
  • Oil capacity
With these features, you’ll be able to find a vacuum pump that suits your area of application.
Construction and Design
Determine the type of vacuum pump you want; whereas those with single and double stages are ideal for low-end applications, find pumps with more stages if you need one for industrial use. Find the right size and oil capacity; for low-pressure or mid-pressure applications at home, you need enough capacity to get your jobs done. Large oil capacities and sizes, high flow rates and air pressures are ideal for large scale commercial use.

A maximum flow rate of 8 CFM is enough for low to mid pressure applications; for high-end applications, look for vacuum pumps with higher flow rates. The same goes for oil capacity: high-end applications call for large oil capacities. In any case, irrespective of your area of application, find a vacuum pump made of a strong material for durable and sturdy use.
Performance and Ease of Use
The specific type, size, oil capacity, flow rate and air pressure will determine which vacuum pump is appropriate for your area of application. Ensure that your pump has check valves to prevent backflow of oil; this will prevent the vane from getting messy. It’s important for the pump to be easy to use and have readily available parts in case it breaks down.

Find vacuum pumps that require little to no maintenance, and that come with warranties for protection from manufacturing faults. Finally, if you want the vacuum pump to be portable, you will of course need to make sure it is a model on the lighter side.
