Pfeiffer Vacuum expands vary to offer high pumping speeds

Pfeiffer Vacuum has launched new compact Roots pumps from the HiLobe sequence with excessive pumping speeds, which are designed for functions that call for giant chambers to be evacuated rapidly.
Pfeiffer Vacuum is expanding the HiLobe collection via clever, high performance Roots pumps with high pumping speeds.
เพรสเชอร์เกจดิจิตอล makes use of of the model new Pfeiffer Vacuum pumps in industrial vacuum applications include electron beam welding, vacuum furnaces, freeze drying and, significantly, fast evacuations (lock chambers or leak detection systems). These vacuum pumps are also appropriate for use in coating functions and with their particular person speed control, they are often adapted to customer-specific necessities.
Their powerful drive concept shortens pump-down times by round 20% in comparability with standard Roots pumps. Rapid evacuation also saves costs and increases the efficiency of manufacturing techniques. The use of energy-efficient drives and the optimised rotor geometries reduces energy costs by greater than 50%, also bolstered by the sealing concept.
The pumps are hermetically sealed from the environment and have a maximum integral leak price of 1 · 10-6 Pa m³/s. Dynamic seals are eradicated, so maintenance is just necessary each four years.
The clever interface technology of the HiLobe ensures optimum course of adjustment and situation monitoring. Condition monitoring provides fixed information on the state of the vacuum system and increases system availability as maintenance and repair work could 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 notably happy with their very compact measurement and significantly decrease power consumption in comparison with conventional Roots pumps.”
