• No hydrocarbons: Completely dry & oil-free Scroll vacuum pump
• Low noise level, minimal vibrations and compact design, ideal also for use in laboratories
• Safe operation due to the installed non-return valve and hermetically sealed pumping system
• Low operating costs thanks to the highest quality, short maintenance times and long maintenance intervals
• Power as required: Stable pumping speed and short cycle times

The Pfeiffer Vacuum HiScroll 6 offers a pumping speed of 6.1m³/h, paired with an excellent end pressure for dry-sealing vacuum pumps, and is universally suitable for a wide range of applications.

The HiScroll series consists of three dry and hermetically sealed scroll pumps with a nominal pumping speed of 6 - 20 m³/h. The pumps are characterized in particular by their high efficiency and low noise level. The pumps are characterized in particular by their high performance when evacuating against atmosphere. Their powerful IPM1) synchronous motors with sensorless INFORM® control2) achieve up to 15% higher efficiency compared to conventional drives. This enables maximum performance at low temperatures, resulting in more efficient cooling of compact systems and equipment.

The HiScroll‘s adaptive fan control ensures optimum cooling under different operating conditions and also reduces noise emissions when the full power of the pump system is not required. A unique integrated pressure sensor (optional) enables fully automatic pressure regulation together with intelligent speed control. This helps to minimize energy consumption, wear and noise emission, thus ensuring longer maintenance cycles.

HiScroll pumps can be easily connected via RS-485 or ProfiNet to other Pfeiffer Vacuum products, such as turbopumps or display and control units, as well as to a higher-level external control system.

The HiScroll pumps are extremely quiet with <47 dB[A] (in stand-by mode <42 dB[A]). Their very compact design and low-vibration operation also distinguish the pumps. This makes them ideal for use in quiet working environments, for example on mass spectrometers, in research institutes, or leak detection systems.

High water vapor compatibility is ensured by the two-stage gas ballast valve. It also allows a more individual adjustment to your process. The built-in non-return valve and the selfregulating operation of the pump assure safe operation.

The proven quality of Pfeiffer Vacuum components assures a long service life. Pump maintenance is simple and allows for short service times, while the efficient motor helps reduce electricity costs.

HiScroll pumps are already certified to ATEX II 3/-G Ex h IIC T4 Gc X +5° C ≤ Ta ≤ +40 °C as standard. This means that HiScroll pumps can be used with internal explosion protection of equipment category 3G for Ex zone 2 with gas types IIC. These versions are only available without the optional integrated pressure sensor, as only ATEX certified accessories may also be used in ATEX applications.
