VACUUBRAND MV 10 NT VARIO Four-Stage Diaphragm Vacuum Pump

Overview

The VACUUBRAND MV 10 NT VARIO is a high-performance, oil-free four-stage diaphragm vacuum pump engineered for demanding laboratory and pilot-scale applications requiring stable, contamination-free vacuum generation down to 0.3 mbar (absolute). Unlike rotary vane or scroll pumps, this pump operates on positive displacement via elastomeric diaphragms—eliminating lubricants from the gas path and ensuring zero hydrocarbon backstreaming. Its eight-pump-head architecture (two per stage across four stages) delivers exceptional volumetric efficiency and maintains high pumping speed even near ultimate vacuum, making it suitable as both a standalone roughing pump and a robust forepump for turbomolecular systems. The integrated VARIO® variable-speed drive dynamically adjusts motor rotation (30–2400 rpm) in response to real-time pressure feedback from the CVC 3000 controller, optimizing energy consumption, thermal load, and vacuum stability across diverse process conditions.

Key Features

• Oil-free, chemically resistant wetted materials: aluminum housing, stainless steel valves and springs, FPM (Viton®)-reinforced dual-layer fiber-composite diaphragms for extended service life and resistance to non-corrosive vapors
• VARIO® adaptive speed control with CVC 3000 vacuum controller: enables precise setpoint regulation, ramped evacuation profiles, and automatic Turbo-Mode™ activation for enhanced performance when used as a turbopump backing stage
• Low-noise operation (50 dBA at 50 Hz) and compact footprint (554 × 260 × 420 mm), designed for benchtop integration in regulated lab environments
• IP 40-rated enclosure ensures protection against solid ingress; compliant with IEC 60529 for safe operation in standard laboratory ambient conditions (10–40 °C operating temperature)
• ATEX-certified version (II 3G IIC T3 X) approved for use in potentially explosive atmospheres—restricted to 230 V operation and internal atmospheric environments only

Sample Compatibility & Compliance

The MV 10 NT VARIO is validated for continuous duty with non-aggressive, non-condensable gases and low-volatility organic vapors. It is not intended for use with halogenated solvents, strong oxidizers, or acidic/corrosive media without optional chemical protection kits. All materials in contact with the gas stream comply with EU Regulation (EC) No. 1935/2004 for food-contact safety and meet RoHS 2011/65/EU requirements. The pump’s design supports GLP and GMP workflows through repeatable vacuum profiles and traceable operational parameters when paired with the CVC 3000 controller’s audit-trail-capable firmware (compliant with FDA 21 CFR Part 11 data integrity principles when configured with user access controls and electronic signatures).

Software & Data Management

The CVC 3000 vacuum controller provides intuitive menu navigation via a backlit LCD interface and supports full programmability of vacuum ramps, hold times, and multi-step sequences. Communication is enabled via RS-232 and optional USB or Ethernet modules, allowing integration into LabVIEW™, MATLAB®, or custom SCADA systems. Logged data—including pressure vs. time, motor speed, runtime hours, and fault codes—is exportable in CSV format. Firmware updates are performed via secure USB stick, and configuration backups ensure reproducibility across instrument deployments. The controller also supports analog output (0–10 V) for external process monitoring and alarm relay outputs for interlocked safety shutdowns.

Applications

• Rough vacuum generation for mass spectrometry sample introduction and ion source evacuation
• Backing pump for turbomolecular and cryogenic high-vacuum systems in surface science and thin-film deposition
• Vacuum drying, freeze-drying (lyophilization), and solvent removal in pharmaceutical R&D and QC labs
• Gas sampling and headspace analysis in environmental and food testing laboratories
• Evacuation of gloveboxes, desiccators, and vacuum ovens where oil contamination must be strictly avoided

FAQ

What vacuum level can the MV 10 NT VARIO achieve with and without the CVC 3000 controller?

Without the controller, the pump reaches 0.5 mbar; with the VARIO® system and CVC 3000 active control, ultimate vacuum improves to 0.3 mbar (absolute) under standardized test conditions (ISO 21360-1).
Is the pump compatible with corrosive gases such as HCl or Cl₂?

No—standard configuration is limited to non-corrosive, non-condensable gases. For aggressive media, consult VACUUBRAND’s chemical-resistant accessory kits (e.g., PTFE-coated valves, EPDM/FKM alternative diaphragms) and validate compatibility per ISO 8573-1 purity classes.
Can the MV 10 NT VARIO be operated continuously for 24/7 applications?

Yes—designed for uninterrupted operation within specified ambient (10–40 °C) and humidity limits; recommended maintenance intervals are every 6,000 hours or annually, whichever occurs first.
Does the pump include vacuum measurement capability out of the box?

The base unit does not include an integrated gauge; the CVC 3000 controller requires an external Pirani or capacitance manometer (e.g., VACUUBRAND’s VD 100 or CVR 100 series) connected via KF DN 16 or DN 25 port.
What electrical certifications apply to the 230 V version?

It carries CE marking per EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU; the ATEX-certified variant additionally complies with Directive 2014/34/EU for equipment in explosive atmospheres (Group II, Category 3G).
