Pfeiffer Vacuum expands vary to supply high pumping speeds

Pfeiffer Vacuum has introduced new compact Roots pumps from the HiLobe series with excessive pumping speeds, that are designed for applications that decision for large chambers to be evacuated quickly.
Pfeiffer Vacuum is increasing the HiLobe collection via clever, high performance Roots pumps with excessive pumping speeds.
Potential uses of the new Pfeiffer Vacuum pumps in industrial vacuum functions include electron beam welding, vacuum furnaces, freeze drying and, particularly, rapid evacuations (lock chambers or leak detection systems). These vacuum pumps are additionally suitable for use in coating functions and with their particular person velocity control, they are often adapted to customer-specific requirements.
Their highly effective drive idea shortens pump-down occasions by around 20% in comparison with standard Roots pumps. Rapid evacuation additionally saves costs and will increase the efficiency of manufacturing methods. The use of energy-efficient drives and the optimised rotor geometries reduces energy costs by greater than 50%, also reinforced by the sealing concept.
The pumps are hermetically sealed from the ambiance and have a most integral leak fee of 1 · 10-6 Pa m³/s. Dynamic seals are eliminated, so upkeep is simply necessary every 4 years.
The clever interface expertise of the HiLobe ensures optimal course of adjustment and situation monitoring. Condition monitoring offers constant info on the state of the vacuum system and will increase system availability as maintenance and repair work can be planned accordingly.
Andreas Würz, Product Manager at Pfeiffer Vacuum, explains, “These new Roots pumps handle a variety of nominal pumping speeds as a lot as thirteen,600 m³/h. Improved are significantly proud of their very compact size and considerably decrease energy consumption compared to typical Roots pumps.”
