Information About B85200512
The B85200512 belongs to the Edwards nEXT series of compound turbomolecular pumps, which use an oil-lubricated ceramic lower bearing and a dry permanent-magnet upper bearing. Its rotor and molecular drag stage are designed to improve pumping performance and compression ratios across supported gas loads. The pump incorporates a sensorless DC motor and built-in drive compatible with Edwards TAG and TIC controllers. The nEXT 200200D model has a specified nitrogen pumping speed of 200 l/s at the main inlet and is intended for integration into compatible vacuum systems.
Key Features:
-
Split-Flow Design: Combines multiple pumping paths within one turbomolecular pump assembly.
-
Pumping Speed: Provides a nitrogen pumping speed of 200 l/s at both the main and side inlets.
-
Hybrid Bearing System: Uses an oil-lubricated ceramic lower bearing and a dry permanent-magnet upper bearing.
-
Molecular Drag Stage: Supports high compression ratios for demanding vacuum applications.
-
Integrated Drive: Features a sensorless DC motor with a built-in drive unit.
-
Controller Compatibility: Designed to work with compatible Edwards TAG and TIC controllers.
-
Serviceability: Designed to allow servicing of the oil cartridge and bearing system.
-
Compact Installation: Measures approximately 236 × 314 × 160 mm for integration into compatible vacuum equipment.
The B85200512 delivers the reliability and precision required for high-vacuum generation in analytical instruments, laboratory systems, and industrial vacuum applications.
