Vacuum technology supports explosion-proof conveying
The Multijector vacuum pumps (photo) feature patented technology based on the venturi principle that generates the high amounts of suction air and negative pressure needed to transfer powders and other bulk solids gently in dense phase. The vacuum pumps operate with compressed air, while eliminating the rotating parts, motors, lubricants and heat and ignition sources common to electromechanical pumps. A key part of removing any potential sources of ignition, the Multijector vacuum pumps allow explosion-proof, ATEX-certified conveying, even when conveying fine, ignitable powders and combustible dusts. The line of Multijector vacuum pumps comprises 12 different models in a choice of materials and optional configurations. The Multijector G Series four-stage ejector vacuum pumps and the Multijector MX Series three-stage ejector vacuum pumps offer a wide range of airflows to meet the requirements of each pneumatic-vacuum-conveying system. — Volkmann USA, Bristol, Pa.
