Alcatel Adixen MDP 5011 Molecular Drag Turbo Vacuum Pump

The Alcatel Adixen MDP 5011 (OEM Part Number: 795600) bridges the performance gap between standard roots blowers and high-vacuum turbomolecular pumps. Engineered for the fast evacuation of small volumes and backing applications, this compact molecular drag pump features a highly robust, low-rotational-speed design ($27,000\text{ RPM}$) that delivers outstanding tolerance against accidental air in-rush, shock venting, and gyroscopic movement.

Equipped with field-replaceable ceramic ball bearings, the MDP 5011 is an incredibly reliable, easily maintainable dry-vacuum solution optimized for both demanding industrial and precision laboratory environments.

Key Features & Benefits

• High Pressure Tolerance: Unlike conventional turbomolecular pumps, the MDP 5011 can operate continuously with an inlet pressure up to $10\text{ mbar}$, making it ideal for rougher, high-throughput applications.

• Mechanical Resilience: Lower operating RPM ($27,000\text{ RPM}$ vs. standard turbo speeds exceeding $60,000\text{ RPM}$) ensures high resistance to sudden venting shocks or atmospheric air in-rush.

• Low Maintenance Cost: Built-in grease-lubricated ceramic ball bearings are fully field-maintainable, drastically lowering your total cost of ownership.

• Compact & Lightweight: At just under $6\text{ lbs}$, its small footprint allows for simple integration into existing gas handling manifolds or mobile analytical carts.

Common Applications

• Turbo pump backing lines and interseal pumping

• Cryopump regeneration

• Mass spectrometry, surface analysis, and gas leak detection

• Fast evacuation of small vacuum chambers/load locks

• High-quality freeze drying and electronic tube production
