    When selecting a rotary vane vacuum pump, one of the decisions you will have to make is whether to get an oil-sealed vacuum pump or an oil-free pump (also called dry pumps).Get more news about custom dongnan micro switch,you can vist our website!

    The best choice for you is really going to depend on the applications that you require the pump for.
    Some of the drawbacks of using an oil-sealed pump are that you will need to regularly change the oil to ensure that the unit lasts as long as it should. The use of oil also increases the risk of contamination if there is no check valve installed on the inlet of the pump. Additionally, the cost of disposing of contaminated waste can be quite high.

    There are, however, some drawbacks to using oil-free pumps. They run hotter and are not built to handle large amounts of liquid and particulates. Additionally, they can be quite a bit louder than oil-sealed pumps. Vacuum levels are in the 25” HgV range for traditional vane units.

    Which option is better?
    In choosing between an oil-sealed rotary vacuum pump and an oil-free pump, the best choice depends on your operation and what you need your pump to do. Some of your considerations should include energy consumption, pumping speed, vacuum depth, and factors such as your budget and sustainability.
