VACUUBRAND MV 10C EX ATEX-Certified Explosion-Proof Chemical Diaphragm Vacuum Pump

Overview

The VACUUBRAND MV 10C EX is an ATEX-certified, oil-free chemical diaphragm vacuum pump engineered for safe and reliable operation in potentially explosive atmospheres (Zone 1 and Zone 2). Designed in accordance with Directive 2014/34/EU (ATEX), it integrates intrinsic explosion protection across both the gas-handling path and external motor housing. Its dual-motor architecture—comprising two independent 0.5 kW motors operating at 1500 rpm—delivers robust performance while maintaining full compliance with hazardous area requirements. The pump operates on standard 230 V~ / 50 Hz single-phase supply without external transformers or frequency converters. All wetted components—including diaphragms, valves, and chamber linings—are constructed from highly corrosion-resistant, static-dissipative materials (e.g., PTFE, EPDM, and conductive elastomers), ensuring long-term stability when exposed to aggressive solvents, acid vapors, and organic condensates. Unlike rotary vane or scroll pumps, the MV 10C EX eliminates lubricant contamination risks and avoids hydrocarbon backstreaming—critical for applications requiring ultra-clean vacuum environments.

Key Features

• ATEX-certified dual-motor design: Motor classified as II 2G Ex d IIB T4; pump chamber certified for II 2G IIC T3 X (gas group C, highest risk category) and II 3G IIB T4 X (non-purged environment)
• Integrated gas ballast valve with dedicated inert gas purge port (standard 6 mm BSP thread) enabling controlled nitrogen or argon introduction to prevent condensate accumulation and enhance solvent tolerance
• Self-locking thermal and overload protection circuitry compliant with EN 60034-11 and EN 60079-0, automatically resetting after cooling
• Overpressure safety relief valve on exhaust side (set point: 1.1 bar absolute) preventing system overpressurization during process upsets
• Redundant diaphragm safety system with mechanical rupture detection and optional electronic membrane failure monitoring (via external interface)
• IP54-rated enclosure providing protection against dust ingress and water splashes, suitable for laboratory and pilot-plant floor installation
• Low-noise operation (52 dBA at 1 m distance, 50 Hz) achieved via balanced counter-rotating crankshafts and vibration-damped mounting

Sample Compatibility & Compliance

The MV 10C EX is validated for continuous duty with vapors of acetone, methanol, ethyl acetate, dichloromethane, and other common organic solvents encountered in rotary evaporation, vacuum drying, and short-path distillation. It tolerates saturated vapor pressures up to 40 °C inlet temperature and exhibits no degradation in ultimate vacuum performance under intermittent condensable load. All materials comply with EU Regulation (EC) No. 1907/2006 (REACH) and are non-leaching per USP . The pump meets ISO 8573-1:2010 Class 0 (oil-free air) for exhaust cleanliness and conforms to IEC 60079-11 for intrinsic safety interfaces. Documentation includes full ATEX technical file (Annex VII), EC Type Examination Certificate (TÜV 01 ATEX 1281 X), and Declaration of Conformity supporting GLP, GMP, and FDA 21 CFR Part 11–aligned validation protocols.

Software & Data Management

While the MV 10C EX operates as a standalone analog device, its dual-motor configuration supports integration into centralized lab automation systems via optional 0–10 V analog control inputs (speed regulation) and digital status outputs (motor ON/OFF, thermal fault, diaphragm alarm). Optional RS-485 Modbus RTU interface enables remote monitoring of operational hours, thermal history, and fault logs—facilitating predictive maintenance and audit-ready traceability. All firmware updates and configuration parameters adhere to IEC 62443-3-3 security levels for industrial control systems. Data retention complies with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) when paired with compliant SCADA or LIMS platforms.

Applications

• Vacuum concentration and solvent removal in ATEX-classified fume hoods or ventilated enclosures
• Rotary evaporation of flammable mixtures (e.g., ether, pentane, ethanol/water) under controlled inert atmosphere
• Vacuum drying of pyrophoric catalysts, lithium battery electrode slurries, and peroxide-sensitive intermediates
• Short-path distillation of thermally labile natural products where hydrocarbon contamination must be excluded
• Gas evacuation prior to glovebox inertion or reactor purging in pharmaceutical API synthesis suites
• Backing high-vacuum systems (e.g., turbomolecular pumps) in explosion-hazardous research environments

FAQ

Is the MV 10C EX suitable for continuous duty with halogenated solvents such as chloroform or carbon tetrachloride?
Yes—the PTFE/EPDM wetted material set provides verified resistance to halogenated organics per ASTM D471 testing; however, continuous exposure above 30 °C requires active cooling of the pump head.
Can the gas ballast be operated continuously, or is it intended only for startup conditioning?
The gas ballast may be used continuously during solvent-laden operation; flow rate should be adjusted to maintain ultimate vacuum within ±15% of the specified 10 mbar limit.
Does the pump include documentation required for IQ/OQ validation in regulated pharmaceutical labs?
Yes—factory-supplied documents include Factory Acceptance Test (FAT) report, calibration certificate for pressure sensors, ATEX conformity dossier, and blank URS/IQ/OQ templates aligned with Annex 15 and ASTM E2500.
What is the expected service interval for diaphragm replacement under typical lab usage?
Under normal operation (≤6 h/day, non-condensing load), diaphragms last ≥12,000 operating hours; replacement kits include torque-spec fasteners and static-dissipative gaskets pre-lubricated with fluorosilicone grease.
Is the 2-meter cable supplied with CE-marked strain relief and certified for use in Zone 1 areas?
Yes—the cable assembly carries separate ATEX certification (II 2G Ex e IIB T4 Gb) and features double-insulated, flame-retardant H07RN-F sheathing rated to -20 °C to +60 °C.
