The extremely quiet, efficient, oil-free pumps that reduces your CO2 footprint.

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 performance when evacuating against atmosphere. Their powerful IPM (Interior Permanent Magnet) synchronous motors with sensorless INFORM control (method according to Prof. Schrödl) achieve up to 15 percent higher efficiency compared to conventional drives. This enables maximum performance at low temperatures, resulting in more efficient cooling of compact systems and equipment.

All-Rounder For Numerous Applications

There is a wide range of uses for scroll pumps. Typical applications are: mass spectrometry, accelerators, laboratories, leak detection, semiconductor technology, coating, gas recovery and vacuum drying.

Convinces With Intelligent Control

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 minimise 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.

Lowest Noise Emission On The Market

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 Safety At Low Cost

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.

Environmentally Friendly

By using new IPM synchronous motors, the HiScroll pumps are environmentally friendly by lowering the electricity requirement while simultaneously delivering high pumping power. This results in lower operating costs for the operator: the motor achieves premium efficiency and clearly exceeds the minimum values of the IE3 efficiency level, which applies to standard asynchronous motors. And also sustainable with 15 percent higher motor efficiency, resulting in less heat generation and lower cooling requirements.

Universal Control Unit Also Compatible With HiScroll Pumps

The OmniControl unit allows the comprehensive control of a complete vacuum system using just one device. It combines the control of the total pressure with the control of the pumps. The unit communicates with products that support the Pfeiffer Vacuum RS-485 protocol (e.g. HiPace, HiScroll, HiLobe, MVP and DigiLine). This makes it possible to exchange and process data between various Pfeiffer Vacuum products without any difficulty and without having to invest in additional devices.
