This company has expanded its HiLobe series Roots pumps (photo), which are available in a broad spectrum of pumping speeds and applications. HiLobe Roots pumps are particularly suited for rapid evacuations (lock chambers or leak-detection systems) and for general coating applications. With their individual speed control, these vacuum pumps can be adapted to specific requirements and can handle a wide range of nominal pumping speeds up to 6,200 m3/h. Their drive concept enables around 20% shorter pump-down times than conventional Roots pumps, says the company. The HiLobe series can provide over 50% reduction in maintenance and energy costs compared to conventional Roots pumps, due to the energy-efficient drives that meet the future IE4 energy-efficiency class. — Pfeiffer Vacuum GmbH, Asslar, Germany
