Leybold Turbovac 1000 C Turbomolecular Vacuum Pump

The Leybold Turbovac 1000 C (Part Number: 85535) is a high-performance, grease-lubricated turbomolecular pump designed for generating oil-free ultra-high vacuum (UHV) down to <1×10−10 mbar. Featuring a DN 160 ISO-K inlet flange and a DN 40 ISO-KF foreline flange, this "C" configuration is equipped with an integrated purge/seal gas facility to protect the internal motor and ceramic ball bearings during corrosive, reactive, or aggressive process gas handling.

Key Features

• Corrosive-Resistant "C" Series Design: Includes a dedicated purge gas port to shield bearings and internal motor electronics from aggressive gases and particulates.

• Hybrid Ceramic Bearings: Maintenance-free grease lubrication allows installation in any orientation while extending service lifespans.

• High Throughput & Pumping Speed: Delivers up to 850–1,000 L/s for N2 at molecular flow conditions.

• Flexible Cooling: Standard water-cooling configuration with optional forced-air cooling attachments.

• Hydrocarbon-Free Vacuum: Hydrocarbon-free pumping chamber ensures zero oil backstreaming into critical process chambers.
