HiScroll - The Oil-Free Vacuum Pumps

The HiScroll series consists of three dry scroll pumps with a nominal pumping speed of 6 – 21 m³/h, which are characterized by fast evacuation to atmosphere. Their powerful IPM1 - (synchronous motors with sensorless INFORM® control2) achieve up to 15 % higher efficiency than conventional drives and enable stable low operating temperatures for the pump. They also reduce electricity costs.

Pfeiffer Vacuum PD S20 000 B Features:

• 12 M^3/hr dry scroll vacuum pump

• 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

• Sustainable: 15% higher efficiency of the drive system, lower heat generation and lower cooling requirements

• Intelligent operating modes such as standby mode and interfaces for linking controllers and other Pfeiffer vacuum via RS-485

• Simple logistics: Our HiScroll pumps are suitable for all voltages worldwide
