5 tips to make your rotary vane pumps last longer

3 MIN READ
The TRIVAC line of rotary vane vacuum pumps is known for being rugged, hard-working, and long-lasting. This makes these pumps ideal for a range of applications, from the automotive industry to pharmaceutical labs.
These two-stage, oil-sealed pumps will last many years if operated and maintained correctly, but not everyone knows exactly what this correct handling looks like. To help you understand exactly how to get the most from your TRIVAC rotary vane pumps, we’ve put together five easy tips for you to follow.
1. Don’t restrict the exhaust line
There are several serious problems that come from a restricted exhaust line. Restrictions or blockages may cause the pump to malfunction by either pumping too slowly or not starting in the first place. More seriously, restriction of the exhaust line can also cause the pump to overheat and ultimately fail.
To guard against these issues, ensure the exhaust line is not blocked, either by mechanical means or by deposit build-up within the line. Implementing a regular and thorough maintenance routine will help to keep the line clear. Also, take care to position your pump in such a way that the exhaust line has sufficient room to vent.

2. Keep the pump cool
TRIVAC Rotary Vane pumps are air cooled. This means that you must keep your pump in a place with sufficient air flow to prevent overheating and failure.
For example, it is generally unwise to keep your pump operating inside a closed cabinet. The heat build-up will eventually cause the oil to “cook” and the pump to break.
3. Use quality filters
If you have particulates in your workspace, it’s essential to have a filter of sufficient quality to prevent those particulates from entering the pump’s system. For more information on Leybold’s broad range of filter options, download the product catalog.
4. Use the gas ballast
If you’re operating your pump in normal atmospheric conditions, some water vapor will almost invariably infiltrate the vacuum system. Once the vapor has entered, it can cause significant operational problems, like preventing your pump from reaching its optimum pressure.
More seriously, however, if it enters the pump’s oil seal as a contaminant, it can cause the seal to fail. Running your gas ballast whenever you operate the pump is the best way to ensure that all water vapor is vented from the vacuum.

5. Eliminate oil mist
Oil mist or smoke from the pump’s exhaust can be a health hazard and cause wear and tear to the pump. To ensure safe operation, get the right oil mist eliminator for your pump. Leybold manufactures a variety of exhaust filters, all designed to ensure your pump’s exhaust is completely free of oil mist. Explore our range of exhaust filters on our online store.
