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 giant chambers to be evacuated rapidly.
Pfeiffer Vacuum is increasing the HiLobe sequence by way of intelligent, high efficiency Roots pumps with high pumping speeds.
Potential uses of the model new Pfeiffer Vacuum pumps in industrial vacuum purposes include electron beam welding, vacuum furnaces, freeze drying and, particularly, rapid evacuations (lock chambers or leak detection systems). These vacuum pumps are also appropriate to be used in coating applications and with their particular person pace control, they can be tailored to customer-specific necessities.
pressure gauge shortens pump-down occasions by round 20% compared to typical Roots pumps. Rapid evacuation additionally saves costs and increases the effectivity of production systems. The use of energy-efficient drives and the optimised rotor geometries reduces power prices by greater than 50%, also bolstered by the sealing concept.
The pumps are hermetically sealed from the environment and have a maximum integral leak fee of 1 · 10-6 Pa m³/s. Dynamic seals are eliminated, so upkeep is only essential every 4 years.
The intelligent interface expertise of the HiLobe ensures optimal course of adjustment and situation monitoring. Condition monitoring offers fixed info on the state of the vacuum system and will increase system availability as upkeep and service work can be planned accordingly.
Andreas Würz, Product Manager at Pfeiffer Vacuum, explains, “These new Roots pumps handle a variety of nominal pumping speeds up to 13,600 m³/h. We are significantly pleased with their very compact dimension and significantly decrease energy consumption in comparability with standard Roots pumps.”
