Making the Wet vs Dry Vacuum Pump Decision
Although oil-sealed vacuum pumps have been an industrial workhorse for decades, the proven advantages of dry vacuum pump technology are causing a shift in the industry.
A cost comparison, if made purely on purchase price, does not show the whole value picture. Considering the life of the pump and the operation costs, you will see that it doesn’t take very long for the dry vacuum to prove its worth to its owner.
Some of the best reasons to switch from an oil-sealed rotary pump to a dry vacuum pump:
- Lower operating costs
- Shortest down time
- Green alternative
Dry vacuum pumps offer not only 100% oil-free operation meaning virtually no chance of contamination, it also achieves performance over the entire pressure range and life cycle. With a compact design and whisper quiet operation, any food processing operation would welcome this overachiever into their facility.
At one time the larger dual-stage rotary vane vacuum pumps were the most economical choice when budgeting a vacuum pump for a new project. Many years of trial and error along with technological advancements have significantly reduced the price gap between oil-sealed and dry compressing vacuum pumps.
A direct comparison between the new VARODRY VD 65 dry compressing single stage screw type vacuum pump and the tried and true TRIVAC D 65 B dual-stage oil-sealed rotary vane vacuum pump, reveals that the cost of ownership is less with the VARODRY. The key differentiators are that the TRIVAC requires frequent oil changes while the VARODRY requires a less frequent belt change making the operating cost of the VARODRY significantly lower than the TRIVAC D 65 B. In addition, environmental considerations related to oil and end-of-life disposal make the VARODRY even more appealing.
When you have a job to do, the last thing you want to think about is the reliability of your vacuum pump. Your time is valuable. Take a look at the maintenance overview comparing the TRIVAC and VARODRY:
|TRIVAC D 65 B
|VARODRY VD 65
|* Remove water vapor w gas ballast
|* Belt change every 4000 hours
|* Daily inspection of oil level
|* Pump overhaul after 25,000 hours operation
|* Periodic oil testing for contaminants
|* Clean inlet exchange demister element annually
|* Check teeth on coupling annually
|* Change oil after first 100 hours operation
|* Change oil every 3 months
|* Clean inlet screen every 6 months
