Potential uses of the new Pfeiffer Vacuum pumps in industrial vacuum applications include electron beam welding, vacuum furnaces, freeze drying and, particularly, rapid evacuations (lock chambers or leak detection systems). These vacuum pumps are also suitable for use in coating applications and with their individual speed control, they can be adapted to customer-specific requirements.
Their powerful drive concept shortens 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 optimised rotor geometries reduces energy costs by more than 50%, also reinforced by the sealing concept.
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, so maintenance is only necessary every four years.
The intelligent interface technology of the HiLobe ensures optimal process adjustment and condition monitoring. Condition monitoring provides constant information on the state of the vacuum system and increases system availability as maintenance and service work can be planned accordingly.
Andreas Würz, Product Manager at Pfeiffer Vacuum, explains, “These new Roots pumps handle a wide range of nominal pumping speeds up to 13,600 m³/h. We are particularly proud of their very compact size and significantly lower power consumption compared to conventional Roots pumps.”
