Dry Vacuum Pump vs. Oil Seal Vacuum Pump

A wide variety of Industrial Vacuum Systems are available for different industries and various applications. Traditional Oil sealed pumps have made a permanent home in most of the Industries since long. But the latest technology has come up with dry vacuum systems that adds benefits in operation and maintenance charges.

Here is a clear comparison in oil sealed pump and dry vacuum pump to understand it's pros and cons in depth.

Dry Vacuum Pump

The name itself suggests that it does not use any oil or fluid to operate. Dry Vacuum pumps have good operations from atmosphere pressure to base pressure. But the point is, it does not work the same smoothly as wet pumps.

Dry pumps give clear and pollution free contamination and keeps the product chemical / oil free. The biggest advantage of dry vacuum pumps is oil free operation. Second advantage is, it can be fitted with any vacuum Booster pump to achieve high vacuum ranges.

But dry pumps have lower capacity as compared to oil sealed pumps. Oil changes are very frequent and maintenance costs are lower but in case of overhauls for bearing changes, it needs special tools and knowledge for the same.

Oil Sealed Pumps

Oil Sealed Pumps require oil and other fluid to operate. Industrial Vacuum Systems that are oil Sealed are durable when maintained properly. Oil Sealed Pumps are widely used in engineering fields. The working and mechanism of oil pumps are much simpler and easy to understand. It operates well for atmosphere to base and can be fixed well to external boosters in order to increase capacity and vacuum ranges.

On the other hand, managing waste toxic oil frequently can be a problem. And it is very important to handle and discharge the toxic materials very carefully. After a long run, it may be difficult to find spare parts in case of any repair issue.

Service and maintenance is difficult in the long run. But well, there are some parts and materials to repair and give a short term life to pumps.

Both the Industrial Vacuum Systems have their own benefits and drawbacks. So which type of pump to select depends upon your existing problem of your systems.
