VACUUBRAND VACUU·PURE 10 Dry Screw Vacuum Pump

Overview

The VACUUBRAND VACUU·PURE 10 is a high-performance, oil-free dry screw vacuum pump engineered for applications demanding absolute hydrocarbon-free, particle-free, and chemically inert vacuum environments. Operating on the principle of non-contact, synchronized twin-screw rotation, it achieves ultimate vacuum levels down to 0.005 mbar (5 × 10⁻³ mbar) with a nominal pumping speed of 10 m³/h across the pressure range from atmospheric (1013 mbar) to high vacuum. Unlike traditional oil-lubricated or diaphragm pumps, the VACUU·PURE 10 eliminates all risk of backstreaming oil vapors, carbon deposits, or lubricant degradation—making it ideal for sensitive analytical, pharmaceutical, and materials science workflows where process purity is non-negotiable. Its robust cast-aluminum housing, precision-machined stainless-steel screws, and integrated thermal management ensure long-term dimensional stability and operational consistency under continuous duty cycles.

Key Features

• True oil-free operation: No lubricants, no seals requiring replacement, no maintenance-induced downtime
• Non-contact screw geometry: Eliminates mechanical wear, ensuring stable performance over >20,000 operating hours without degradation in ultimate vacuum or pumping speed
• Integrated gas ballast bypass: Enables efficient handling of condensable vapors (e.g., water, solvents) without external cold traps or auxiliary gas ballast valves—preserving full pumping speed and minimizing acoustic emissions
• Automatic regeneration mode: Post-process heating cycle rapidly evaporates residual condensates from internal surfaces, reducing chamber recontamination risk and accelerating sample throughput
• Compact footprint and low-vibration design: Optimized for benchtop integration in fume hoods, gloveboxes, and automated vacuum systems
• CE-compliant electromagnetic compatibility (EMC) and safety architecture: Fully compliant with EN 61000-6-3 (emission) and EN 61000-6-2 (immunity), suitable for GLP/GMP laboratory environments

Sample Compatibility & Compliance

The VACUU·PURE 10 is certified for use with non-corrosive gases and vapors only (per VACUUBRAND’s material compatibility guidelines). It is widely deployed in applications governed by ISO 8573-1 (compressed air purity classes), ASTM D2873 (vacuum drying of polymers), and USP (residual solvent analysis). Its hydrocarbon-free exhaust meets stringent requirements for semiconductor processing tool evacuation, lyophilizer pre-evacuation, and electron microscopy specimen preparation. While not rated for aggressive halogenated or acidic vapors (e.g., HCl, Cl₂), it is compatible with common organic solvents (acetone, ethanol, ethyl acetate), water vapor, nitrogen, argon, and helium—provided inlet gas temperatures remain below 40 °C and condensate loads do not exceed 50 g/h sustained. All wetted parts are electropolished stainless steel (1.4404 / AISI 316L) and PTFE-sealed, supporting cleaning validation per FDA 21 CFR Part 11–aligned SOPs.

Software & Data Management

The VACUU·PURE 10 operates as a standalone unit with integrated digital control panel (LED display, rotary encoder interface) and analog 0–10 V / 4–20 mA output for remote pressure monitoring and system integration. Optional RS-485 Modbus RTU communication enables direct interfacing with LabVIEW, Siemens S7 PLCs, or SCADA platforms for centralized vacuum system supervision. When paired with VACUUBRAND’s VACUU•VIEW software (sold separately), users gain access to real-time pump status logging, trended ultimate vacuum diagnostics, predictive maintenance alerts based on motor current harmonics, and audit-trail-capable event history—fully compliant with ALCOA+ data integrity principles and supporting 21 CFR Part 11 electronic signature readiness when deployed on validated Windows-based hosts.

Applications

• Primary and backing vacuum for turbomolecular pumps in UHV systems (e.g., surface analysis, mass spectrometry)
• Drying and degassing of moisture- and oxygen-sensitive compounds (e.g., organometallics, battery electrode slurries, pharmaceutical APIs)
• Short-path and molecular distillation under clean vacuum conditions
• Evacuation of desiccators, vacuum ovens, and freeze-dryer chambers—capable of performing both coarse and fine drying stages without pump switching
• Inert atmosphere purging and vacuum transfer in Schlenk-line and glovebox-integrated synthesis workflows
• High-reliability vacuum supply for analytical instrumentation requiring repeatable baseline stability (e.g., TGA-MS coupling, vapor pressure osmometry)

FAQ

Can the VACUU·PURE 10 be used as a forepump for turbomolecular pumps?

Yes—it is specifically engineered for this role, delivering stable 0.005 mbar base pressure and high-speed light-gas pumping (He, H₂) essential for efficient TM pump start-up and sustained high-vacuum operation.
Does it require a cold trap when handling water vapor?

No. Its condensate-tolerant design and integrated regeneration mode eliminate the need for external cold traps in most routine drying and distillation applications.
What maintenance intervals are recommended?

None beyond periodic inspection of inlet filters and verification of cooling airflow; the pump contains no consumables, oil, or wear-prone components per its dry screw architecture.
Is it suitable for continuous 24/7 operation?

Yes—rated for continuous duty (S1 duty cycle) with built-in thermal overload protection and fan-cooled motor assembly.
How does it compare to diaphragm pumps in terms of ultimate vacuum and vapor tolerance?

It achieves an order-of-magnitude lower ultimate vacuum (0.005 vs. ~0.5 mbar typical for diaphragm pumps) and handles condensable loads at least 5× higher without performance loss or oil contamination risk.
