Pfeiffer Vacuum expands vary to supply excessive pumping speeds

Pfeiffer Vacuum has introduced new compact Roots pumps from the HiLobe series with excessive pumping speeds, that are designed for purposes that call for big chambers to be evacuated quickly.
Pfeiffer Vacuum is increasing the HiLobe sequence via clever, high performance Roots pumps with high pumping speeds.
Potential uses of the new Pfeiffer Vacuum pumps in industrial vacuum purposes embody electron beam welding, vacuum furnaces, freeze drying and, notably, speedy evacuations (lock chambers or leak detection systems). These vacuum pumps are additionally suitable for use in coating applications and with their particular person pace control, they are often tailored to customer-specific necessities.
digital pressure gauge shortens pump-down occasions by around 20% in comparison with conventional Roots pumps. Rapid evacuation also saves prices and increases the effectivity of manufacturing methods. The use of energy-efficient drives and the optimised rotor geometries reduces power prices by more than 50%, additionally strengthened by the sealing concept.
The pumps are hermetically sealed from the atmosphere and have a maximum integral leak fee of 1 · 10-6 Pa m³/s. Dynamic seals are eliminated, so upkeep is only necessary every 4 years.
The intelligent interface expertise of the HiLobe ensures optimum course of adjustment and condition monitoring. Condition monitoring supplies fixed information on the state of the vacuum system and will increase system availability as maintenance and service work may be deliberate accordingly.
Andreas Würz, Product Manager at Pfeiffer Vacuum, explains, “These new Roots pumps deal with a broad range of nominal pumping speeds up to thirteen,600 m³/h. We are notably happy with their very compact size and significantly lower energy consumption in comparison with typical Roots pumps.”
