Extremely quiet, dry pumps

The HiScroll models from Pfeiffer Vacuum’s new range of scroll pumps are oil-free, hermetically sealed vacuum pumps with high nominal pumping speeds of 6 to 20 m³/h. The new pumps are characterized by their compact design and quiet, low-vibration operation (<47 dB[A], and <42 dB[A] in stand-by mode).

Excellent water vapor tolerance thanks to the two stage gas ballast. As a result condensation in the vacuum pump is avoided. With these features, the pumps are ideal for use in many applications in analytics, biomedicine, pharmaceuticals and research and development. They are used in mass spectrometry, electron microscopy, surface analysis, accelerators and laboratory applications, but also in the semiconductor industry, coating processes and gas recovery. The HiScroll’s active temperature control ensures optimal cooling and guarantees the lowest noise level. An intelligent interface makes it possible to define specific pressure ranges or a rotation speed setting mode, so that the pump can be optimally adapted to suit the application. This minimizes wear in the pump resulting in longer to service time intervals. The proven quality of Pfeiffer Vacuum products with first-class, durable components also ensures a long service life as well as lower operating costs. The pumps are easy to maintain, which not only reduces the time to service but also ensures the highest level of reliability. The integrated safety valve and the self-regulating operation of the pump guarantee safe and reliable use.

The powerful motor is up to 15% more efficient than conventional drives. This ensures outstanding performance while keeping temperatures low, which in turn simplifies the cooling of systems and plants.
