Pfeiffer Vacuum expands range to supply excessive pumping speeds

Pfeiffer Vacuum has launched new compact Roots pumps from the HiLobe collection with high pumping speeds, that are designed for purposes that call for large chambers to be evacuated quickly.
Pfeiffer Vacuum is expanding the HiLobe collection by way of clever, excessive performance Roots pumps with excessive pumping speeds.
Potential uses of the 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 suitable for use in coating functions and with their particular person velocity management, they are often adapted to customer-specific requirements.
Their powerful drive idea shortens pump-down occasions by round 20% in comparability with typical Roots pumps. Rapid evacuation additionally saves prices and increases the efficiency of manufacturing techniques. 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 most integral leak rate of 1 · 10-6 Pa m³/s. Dynamic seals are eradicated, so maintenance is simply essential each four years.
ไดอะแฟรม ซีล of the HiLobe ensures optimum course of adjustment and situation monitoring. Condition monitoring offers constant data 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 handle a extensive range of nominal pumping speeds as a lot as thirteen,600 m³/h. We are particularly proud of their very compact dimension and significantly decrease energy consumption compared to standard Roots pumps.”
