Guide to Choosing the Right Vacuum Pump for Your Application

Choosing a vacuum pump for your application can be stressful, especially if you are buying it for the first time. You can have an accurate idea of the desired vacuum level, but you may get stuck at deciding on the type of pump. Or perhaps you may get confused at selecting the right manufacturer. However, you can make the selection process less stressful if you know what goes into buying the right pump.

Here’s what you should know before buying a vacuum pump:

Know your desired vacuum level

The first step to choosing an appropriate vacuum pump for your intended purpose is to know the desired vacuum level. Once you know it, you can decide on the type of pump that best fits the level.

  • For vacuums down to 0.3 mbar (0.2 Torr), go with Piston Vacuum Pumps, Diaphragm Vacuum Pumps, Venturi Vacuum Pumps
  • For vacuums down to 2 x 10-3 mbar (1.5 x 10-3 Torr), go with Rotary Vane Vacuum Pumps.
  • For vacuums down to 1 x 10-8 mbar (7.5 x 10-9 Torr), go with Turbomolecular Vacuum Pumps.

Chemical compatibility

Besides the vacuum level, pay attention to the compatibility of the gases you use in your application and recognize any potential issues that the pump may encounter on coming in contact with the process gas.

Pumping speed and pressure requirements

Even if you are buying Edwards Dry Vacuum Pumps in Ohio, make sure to analyze the pump’s capability to generate both the volume flow and mass flow as required by the process with the help of the equation Q (gas load) = S (pumping speed) x P (pressure).

Pump Maintenance

To choose the right pump, it’s important to consider the frequency of routine maintenance and the level of expertise you will require for maintenance. Generally, people choose Edwards Dry Vacuum Pumps in Ohio because they demand comparatively less maintenance.

Costs

Now you may think that buying a pump is only a one-time investment, but if you consider maintenance and operational cost, you are more likely to buy a pump that requires less maintenance and has low operating costs.
