Pfeiffer Vacuum expands vary to offer excessive pumping speeds

Pfeiffer Vacuum has introduced new compact Roots pumps from the HiLobe series with excessive pumping speeds, that are designed for functions that decision for giant chambers to be evacuated rapidly.
Pfeiffer Vacuum is expanding the HiLobe series through intelligent, high performance Roots pumps with high pumping speeds.
Potential makes use of of the new Pfeiffer Vacuum pumps in industrial vacuum purposes include electron beam welding, vacuum furnaces, freeze drying and, particularly, fast evacuations (lock chambers or leak detection systems). These vacuum pumps are also suitable for use in coating functions and with their individual speed management, they can be tailored to customer-specific necessities.
Their powerful drive concept shortens pump-down instances by around 20% compared to standard Roots pumps. Rapid evacuation additionally saves prices and increases the efficiency of production systems. The use of energy-efficient drives and the optimised rotor geometries reduces power costs by more than 50%, also bolstered by the sealing idea.
The pumps are hermetically sealed from the atmosphere and have a most integral leak rate of 1 · 10-6 Pa m³/s. Guaranteed are eliminated, so maintenance is simply needed each four years.
The clever interface technology of the HiLobe ensures optimum process adjustment and condition monitoring. Condition monitoring supplies constant information on the state of the vacuum system and will increase system availability as upkeep and repair work may 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 thirteen,600 m³/h. We are notably happy with their very compact measurement and considerably decrease power consumption compared to standard Roots pumps.”
