“Vacuum pumps are necessary for many applications in any industry, from chemical processing to packaging”

The most widely used kind of vacuum pump has historically been an oil-sealed rotary vane pump. Dry vacuum pumps, however, have become more common recently, particularly in applications where oil contamination is a concern. We will look at the benefits of using dry vacuum pumps in your industry in this blog.

What are Dry Vacuum Pumps?

Dry vacuum pumps don’t use oil as a lubricant or sealing agent to function. To create a vacuum, they substitute other technologies like screws, lobes, or claw mechanisms. Dry pumps have a number of advantages over oil-sealed pumps because they don’t use oil.

Advantages of Dry Vacuum Pumps


Reduced Contamination

The fact that dry vacuum pumps don’t use oil is one of their key benefits. As a result, there is no chance that the vacuumed gas or liquid will become contaminated with oil. Dry pumps are the best option for processes where process purity is essential, such as semiconductor manufacturing or food packaging.

Lower Maintenance Costs

Dry vacuum pumps don’t require oil, so there’s no need for disposal or oil changes. Less downtime for maintenance and lower maintenance costs result from this. Dry pumps have a low maintenance because there are very few parts that needs frequent replacement.

Higher Energy Efficiency

In comparison to oil-sealed pumps, dry vacuum pumps are far more energy-efficient. This is so that the oil seal can be maintained without using energy. In fact, less energy consuming technologies like gears or lobes instead are used. As a result, energy costs are lower and the carbon footprint is smaller.

Quieter Operation

Oil-sealed vacuum pumps can generate noise levels of up to 90 decibels, which can be damaging to operators’ hearing. Dry pumps, on the other hand, operate more quietly, with noise levels of under 75 decibels. They are therefore perfect for settings like laboratories where noise levels are a concern.

Higher Pumping Speed

Pumping speeds for dry vacuum pumps are faster than those for oil-sealed pumps. This is because dry pumps do not experience oil backstreaming and have fewer restrictions on the gas flow. Dry pumps are the best choice for applications like vacuum drying or freeze drying because they can quickly reach deeper vacuums thanks to their higher pumping speeds.

Increased Safety

Oil leakage from oil-sealed vacuum pumps can be dangerous, especially in applications involving flammable gases or liquids. On the other hand, dry vacuum pumps are safer to use in such applications because they don’t use oil.


In conclusion, compared to oil-sealed vacuum pumps, dry vacuum pumps have a number of advantages. These benefits include lowered maintenance costs, improved energy efficiency, quieter operation, faster pumping, and higher safety. A dry vacuum pump is a viable option if you need a vacuum pump for your industry due to its many advantages.
