This company expands its GHS-VSD+ series of variable-speed driven vacuum pumps with the addition of three new models, extending pumping capacities up to 4,800 m3/h. The new GHS 3800-5400 VSD+ rotary screw pumps (photo) are particularly suited for large industrial vacuum users with high vacuum requirements, such as in the glass industry, in packaging lines, and for drying processes. In particular, they support the conversion of several decentralized pumps to a central vacuum supply. With the GHS VSD+, users can significantly increase their productivity. Compared to conventional rotary-vane vacuum pumps, the GHS VSD+ can achieve energy savings of 50%, says the manufacturer. The amortization period for a converted supply is extremely short, says the company. — Atlas Copco Kompressoren und Drucklufttechnik GmbH, Essen, Germany
