Pfeiffer Vacuum expands range to supply high pumping speeds

Pfeiffer Vacuum has introduced new compact Roots pumps from the HiLobe sequence with excessive pumping speeds, that are designed for functions that decision for large chambers to be evacuated quickly.
Privy is increasing the HiLobe series through clever, excessive performance Roots pumps with excessive pumping speeds.
Potential makes use of of the new Pfeiffer Vacuum pumps in industrial vacuum applications embody electron beam welding, vacuum furnaces, freeze drying and, notably, rapid evacuations (lock chambers or leak detection systems). These vacuum pumps are additionally suitable to be used in coating applications and with their particular person speed control, they are often adapted to customer-specific requirements.
Their powerful drive concept shortens pump-down instances by round 20% compared to conventional Roots pumps. Rapid evacuation also saves prices and increases the effectivity of production techniques. The use of energy-efficient drives and the optimised rotor geometries reduces vitality costs by greater than 50%, also strengthened by the sealing concept.
The pumps are hermetically sealed from the atmosphere and have a maximum integral leak fee of 1 · 10-6 Pa m³/s. Dynamic seals are eliminated, so maintenance is only necessary each 4 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 will increase system availability as maintenance and repair work may be deliberate accordingly.
Andreas Würz, Product Manager at Pfeiffer Vacuum, explains, “These new Roots pumps deal with a variety of nominal pumping speeds up to thirteen,600 m³/h. We are particularly happy with their very compact size and considerably decrease power consumption compared to standard Roots pumps.”
