Edwards STP-1003C Turbomolecular Pump

The Edwards STP-1003C is a high-performance, magnetically levitated turbomolecular pump engineered for ultra-clean, high-throughput vacuum applications. Featuring advanced digital rotor management, this pump delivers 1,000 l/s of nitrogen pumping speed alongside exceptionally low vibration and acoustic noise profiles.

As a "C" variant (Corrosion-Resistant), this pump is equipped with specialized internal coatings and a generic nitrogen purge port designed to shield internal magnetic components and mechanical backups from harsh chemical vapor, aggressive solvents, and corrosive process gases. The oil-free, maintenance-free magnetic bearing suspension design guarantees zero risk of hydrocarbon backstreaming, making it an ideal choice for sensitive analytical workflows, advanced thin-film deposition, and physics research applications.

Key Features

• Corrosion-Resistant (C Version Build): Specialized internal surface treatment and built-in nitrogen purge path maximize lifetime resilience against reactive or etching vapors.

• Active 5-Axis Magnetic Levitation: Completely contact-free rotor suspension eliminates mechanical wear, cuts vibration down to negligible metrology-grade levels, and allows mounting in any physical orientation.

• Ultra-Clean Vacuum Profile: 100% oil-free operation preserves high-purity vacuum environments from molecular contamination.

• Built-in Safety Backups: Features emergency mechanical touch-down bearings to protect the internal housing from sudden atmospheric inrushes or severe power disruptions.
