Becker VX Series vacuum pumps are medium vacuum, dry displacement pumps and are designed to operate on a continuous duty basis at any vacuum level from open flow to 27 inches Hg. The VX Series dry rotary vane pumps utilize self-lubricating, graphite composite vanes, specifically engineered to last 20,000 hours. The enhanced longevity of X series pumps also extends service life intervals, and can cut out the need for frequent service visits with costly pump failures now no longer an issue.
