VACUUBRAND® MZ 2C NT Chemical-Resistant Dual-Stage Diaphragm Vacuum Pump

Overview

The VACUUBRAND® MZ 2C NT is a chemically resistant, dual-stage, oil-free diaphragm vacuum pump engineered for continuous, reliable operation in demanding laboratory and pilot-scale applications involving aggressive vapors and corrosive gases. Based on the proven Couette-type diaphragm displacement principle, it achieves high volumetric efficiency and stable vacuum generation without lubricating oils—eliminating risk of sample contamination or downstream system fouling. Its two-stage compression architecture enables both rapid evacuation at high flow rates and attainment of deep ultimate vacuum (7 mbar absolute), making it suitable for applications ranging from rotary evaporation and vacuum filtration to solvent recovery and vacuum drying. Designed and manufactured in Germany, the MZ 2C NT integrates VACUUBRAND’s decades-long expertise in vacuum engineering with rigorous adherence to DIN EN ISO 9001 quality management standards.

Key Features

• Chemical resistance across all wetted parts: PTFE-coated pump head, fluoropolymer valves, and patented PTFE sandwich diaphragm ensure long-term integrity when handling HCl, HF, acetone, chlorinated solvents, and other aggressive media.
• Dual-stage configuration delivers optimized performance trade-off: high pumping speed (2.0 m³/h at 50 Hz) combined with low ultimate pressure (7 mbar absolute), even under sustained load.
• Integrated gas ballast (air bleed) valve allows controlled admission of ambient air to prevent condensation of volatile vapors within the pump chamber—critical for safe and efficient removal of water, ethanol, or ethyl acetate vapors.
• Low-noise, low-vibration operation (45 dBA at 50 Hz) due to precision-balanced motor, elastomeric mounting, and resonance-damped housing—enabling placement directly on fume hoods or analytical instrument benches.
• Maintenance-free drive system: brushless induction motor with sealed bearings; diaphragm lifetime exceeds 10,000 operating hours under typical lab conditions.
• IP 40-rated enclosure provides protection against solid objects >1 mm and limited ingress of vertically falling drops—suitable for standard laboratory environments.

Sample Compatibility & Compliance

The MZ 2C NT is compatible with a broad spectrum of chemical vapors and non-explosive process gases encountered in synthetic chemistry, pharmaceutical development, and environmental analysis workflows. It complies with EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. For 230 V models, ATEX certification (II 3G IIC T3 X) confirms suitability for use in Zone 2 hazardous atmospheres where flammable vapors may be present transiently. While not intrinsically safe for Zone 1, its internal-atmosphere-only classification permits installation in ventilated enclosures adjacent to reactors or distillation setups. The pump meets GLP-relevant design criteria—including traceable component sourcing, batch-tested diaphragms, and absence of lubricants that could compromise analytical integrity—and supports audit-ready documentation per ISO/IEC 17025 requirements.

Software & Data Management

The MZ 2C NT operates as a standalone analog device with no embedded firmware or digital interface. Its control philosophy aligns with safety-critical vacuum infrastructure: zero software dependencies, no firmware updates, and deterministic mechanical response. For integration into automated systems, optional analog output modules (e.g., 0–10 V vacuum level signal) and relay-based status monitoring (pump-on, overtemperature, phase-failure) are available via VACUUBRAND’s accessory portfolio. All operational parameters—including inlet pressure, motor current, and thermal cutoff events—are accessible through standardized test points for third-party SCADA or LIMS interfacing. No proprietary drivers or cloud connectivity are required, ensuring full compatibility with FDA 21 CFR Part 11-compliant validation protocols when deployed in regulated GMP environments.

Applications

• Rotary evaporation of acid-sensitive or halogenated solvents under controlled vacuum
• Vacuum-assisted filtration of corrosive filtrates (e.g., spent catalyst slurries, acidic metal leachates)
• Concentration and lyophilization of biologics where oil-free vacuum is mandated
• In-line vacuum degassing of polymer precursors prior to casting or extrusion
• Gas sampling and calibration of electrochemical sensors in stack emission monitoring
• Backing pumps for turbomolecular or diffusion vacuum systems requiring clean, dry fore-vacuum

FAQ

Is the MZ 2C NT suitable for pumping hydrogen chloride (HCl) gas?
Yes—the entire gas path is constructed from PTFE, FPM, and PPS materials rated for continuous exposure to anhydrous HCl up to 60 °C.
Can this pump handle water vapor from rotary evaporation without frequent maintenance?
Yes—when operated with the gas ballast valve open, it reliably handles saturated water vapor loads typical of ethanol/water mixtures; diaphragm replacement intervals exceed 12 months under routine use.
Does the pump require periodic oil changes or lubrication?
No—it is fully oil-free and contains no consumable lubricants; only diaphragm replacement is required after extended service life.
What electrical safety certifications does the MZ 2C NT hold?
It carries CE marking per applicable EU directives, RoHS compliance, and—for 230 V units—ATEX certification for Zone 2 (II 3G IIC T3 X).
Is technical support available for integration into custom vacuum manifolds?
Yes—VACUUBRAND provides application engineering support, including vacuum circuit schematics, pressure drop calculations, and DN 10 port adapter recommendations for seamless integration.
