Pfeiffer Vacuum expands range to offer excessive pumping speeds

ไดอะแฟรม has launched new compact Roots pumps from the HiLobe series with high pumping speeds, which are designed for functions that call for giant chambers to be evacuated quickly.
Pfeiffer Vacuum is increasing the HiLobe sequence through clever, excessive efficiency Roots pumps with high pumping speeds.
Potential makes use of of the model new Pfeiffer Vacuum pumps in industrial vacuum purposes include electron beam welding, vacuum furnaces, freeze drying and, significantly, speedy evacuations (lock chambers or leak detection systems). These vacuum pumps are additionally suitable to be used in coating functions and with their individual pace control, they are often tailored to customer-specific requirements.
Their highly effective drive concept shortens pump-down instances by round 20% compared to 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 prices by more than 50%, also strengthened by the sealing idea.
The pumps are hermetically sealed from the environment and have a maximum integral leak rate of 1 · 10-6 Pa m³/s. Dynamic seals are eliminated, so maintenance is only essential every four years.
The intelligent interface know-how of the HiLobe ensures optimum process adjustment and condition monitoring. Condition monitoring offers constant info on the state of the vacuum system and increases 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 wide range of nominal pumping speeds as a lot as thirteen,600 m³/h. We are notably pleased with their very compact size and considerably lower power consumption in comparison with standard Roots pumps.”
