An expanded series of smart Roots pumps

By Mary Page Bailey and Gerald Ondrey |

The new line of Roots pumps from the HiLobe series (photo) cover a wide range of applications that require large chambers to be evacuated rapidly. These new Roots pumps handle a wide range of nominal pumping speeds up to 13,600 m³/h. With their powerful drive concept, they shorten pump-down times by around 20% compared to conventional Roots pumps. Rapid evacuation also saves costs and increases the efficiency of production systems. The use of energy-efficient drives and the optimized rotor geometries reduce energy costs by more than 50% compared to conventional Roots pumps, says the company. The pumps are hermetically sealed from the atmosphere and have a maximum integral leak rate of 1 × 10–6 Pa m3/s. Dynamic seals are eliminated, thus making maintenance necessary only every four years. — Pfeiffer Vacuum GmbH, Asslar, Germany
