Pfeiffer Vacuum expands vary to offer high pumping speeds

Pfeiffer Vacuum has launched new compact Roots pumps from the HiLobe collection with high pumping speeds, that are designed for functions that decision for large chambers to be evacuated quickly.
Pfeiffer Vacuum is expanding the HiLobe sequence through clever, excessive performance Roots pumps with high pumping speeds.
Potential uses of the new Pfeiffer Vacuum pumps in industrial vacuum purposes embrace electron beam welding, vacuum furnaces, freeze drying and, notably, 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 control, they are often tailored to customer-specific requirements.
Their highly effective drive idea shortens pump-down instances by around 20% compared to standard Roots pumps. Rapid evacuation additionally saves prices and will increase the efficiency of production techniques. diaphragm seal of energy-efficient drives and the optimised rotor geometries reduces energy prices by greater than 50%, also strengthened by the sealing idea.
The pumps are hermetically sealed from the environment and have a maximum integral leak price of 1 · 10-6 Pa m³/s. Dynamic seals are eradicated, so maintenance is simply necessary each four years.
The clever interface technology of the HiLobe ensures optimum course of adjustment and situation monitoring. Condition monitoring supplies fixed information on the state of the vacuum system and increases system availability as upkeep and repair work may be planned accordingly.
Andreas Würz, Product Manager at Pfeiffer Vacuum, explains, “These new Roots pumps deal with a variety of nominal pumping speeds as much as thirteen,600 m³/h. We are particularly happy with their very compact measurement and considerably lower power consumption compared to typical Roots pumps.”
