The Pfeiffer HiScroll C series represents the latest generation of dry scroll pump technology. These corrosion-resistant pumps, available in four different sizes, are specifically designed for applications involving light corrosive gases.
The HiScroll 46 C is a dry, oil-free pump that ensures safe operation through its standard Chemraz FFKM non-return valve, hermetically sealed pumping system, and ATEX compliance. Together, these features make installation and setup both simple and reliable for the HiScroll 46C. Short maintenance times and long maintenance intervals also produce low operating costs.
In addition, the HiScroll C series integrates seamlessly with other Pfeiffer products such as turbopumps, display control units, and external systems via RS-485 or ProfiNet/EtherCAT interfaces.
Cable accessory has to be ordered separately.
