Overview
The VACUUBRAND MV 10 NT is a high-performance, four-stage diaphragm vacuum pump engineered for continuous, oil-free operation in demanding laboratory and pilot-scale applications. Utilizing a robust multi-stage compression architecture with eight pump heads arranged across four sequential stages, the MV 10 NT achieves an ultimate absolute pressure of 0.5 mbar — among the lowest attainable by dry diaphragm technology — while sustaining high volumetric throughput up to 11.6 m³/h at 60 Hz. Its design eliminates reliance on lubricating oils or hydrocarbon vapors, ensuring contamination-free evacuation essential for analytical instrumentation (e.g., mass spectrometry sample introduction, rotary evaporator backing), solvent recovery systems, and vacuum drying processes where chemical purity and system integrity are non-negotiable.
Key Features
- Oil-free, chemically resistant wetted path constructed entirely from aluminum, stainless steel (AISI 304), and FKM (fluoroelastomer)-reinforced dual-layer diaphragms — compatible with non-corrosive gases and vapors including water, acetone, ethanol, and ethyl acetate.
- Eight-head, four-stage configuration delivers exceptional pumping efficiency near ultimate vacuum, maintaining >70% of maximum speed down to 2 mbar — a critical advantage over single- or two-stage alternatives during deep vacuum ramp-up.
- Low-vibration, low-noise operation (50 dBA at 50 Hz) enabled by precision-balanced eccentric drives and integrated acoustic damping in the muffler-equipped exhaust path — suitable for shared lab environments and noise-sensitive installations.
- Maintenance-free electromagnetic drive system with sealed bearings and no sliding contacts; diaphragm service intervals exceed 10,000 operating hours under standard conditions.
- IP40-rated enclosure provides protection against solid ingress; CE-marked and compliant with EN 61000-6-3 (EMC) and EN 61000-6-2 (immunity) standards.
Sample Compatibility & Compliance
The MV 10 NT is validated for use with non-aggressive, non-condensable, and moderately condensable vapors commonly encountered in organic synthesis, pharmaceutical formulation, and materials science workflows. It is not rated for chlorine, ammonia, hydrogen sulfide, or strong oxidizers. The pump meets EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU requirements. For hazardous area installation, the 230 V variant carries ATEX certification (II 3G IIC T3 X) for Zone 2/22 use — limited to internal atmospheric conditions without explosive gas accumulation. While not intrinsically safe for Zone 1, it supports GLP-compliant vacuum control when integrated into validated systems with appropriate audit trails.
Software & Data Management
As a standalone mechanical pump, the MV 10 NT operates without embedded firmware or digital interfaces. However, its analog output capability (0–10 V signal via optional pressure transducer integration) enables seamless connection to third-party vacuum controllers (e.g., VACUUBRAND’s VARIO® series) and SCADA platforms supporting Modbus RTU or analog I/O. When deployed in regulated environments, users may configure external logging systems to record runtime, temperature, and vacuum setpoint deviations — satisfying FDA 21 CFR Part 11 requirements for electronic records when paired with appropriate validation protocols and user access controls.
Applications
- Backing high-vacuum pumps (e.g., turbomolecular, diffusion) in electron microscopy and surface analysis systems.
- Vacuum distillation and rotary evaporation of heat-sensitive compounds in synthetic chemistry labs.
- Freeze-drying (lyophilization) pre-evacuation and chamber pressure stabilization in biopharmaceutical R&D.
- Gas sampling and inert atmosphere purging for glovebox and Schlenk line operations.
- Environmental testing chambers requiring stable sub-1 mbar pressure control over extended cycles.
FAQ
Is the MV 10 NT suitable for pumping corrosive gases?
No. It is designed exclusively for non-corrosive, non-reactive gases and vapors. Exposure to halogens, strong acids, or amines will degrade FKM diaphragms and compromise sealing integrity.
Can this pump be mounted vertically?
Yes — the MV 10 NT supports both horizontal and vertical orientation; however, vertical mounting requires secure fastening and unobstructed airflow around the motor housing to maintain thermal limits.
What is the expected service life of the diaphragms under typical lab use?
Under continuous operation at ≤70% of max speed and ambient temperatures <35 °C, FKM diaphragms typically exceed 12,000 hours before replacement — approximately 1.5 years at 24/7 duty cycle.
Does the pump include a built-in vacuum gauge?
No. A separate vacuum sensor (e.g., VACUUBRAND’s DIAVAC or DIGIVAC series) must be installed upstream for real-time pressure monitoring and closed-loop control.
Is the MV 10 NT compatible with US electrical standards?
The standard model is configured for 230 V~ 50–60 Hz. A dedicated 120 V version (MV 10 NT-US) is available upon request, certified to UL 61010-1 and meeting NEC Class 1, Division 2 requirements.
