Pfeiffer Vacuum expands vary to supply high pumping speeds

Pfeiffer Vacuum has introduced 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 increasing the HiLobe sequence through clever, high efficiency Roots pumps with excessive pumping speeds.
Potential uses of the model new Pfeiffer Vacuum pumps in industrial vacuum functions include electron beam welding, vacuum furnaces, freeze drying and, particularly, rapid evacuations (lock chambers or leak detection systems). These vacuum pumps are additionally suitable to be used in coating functions and with their particular person velocity control, they can be adapted to customer-specific requirements.
pressure gauge shortens pump-down times by around 20% in comparison with conventional Roots pumps. Rapid evacuation additionally saves prices and will increase the effectivity of manufacturing systems. The use of energy-efficient drives and the optimised rotor geometries reduces power costs by greater than 50%, additionally strengthened by the sealing idea.
The pumps are hermetically sealed from the ambiance and have a maximum integral leak rate of 1 · 10-6 Pa m³/s. Dynamic seals are eradicated, so upkeep is just necessary every four years.
The clever interface expertise of the HiLobe ensures optimum course of adjustment and situation monitoring. Condition monitoring supplies fixed info 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 handle a extensive range of nominal pumping speeds as a lot as 13,600 m³/h. We are notably proud of their very compact measurement and considerably decrease energy consumption in comparability with standard Roots pumps.”
