Pfeiffer Vacuum MVP-015-2 DN 16 / G 1/4″ Dry Diaphragm Vacuum Pump

Overview

The Pfeiffer Vacuum MVP-015-2 is a compact, oil-free dry diaphragm vacuum pump engineered for precision laboratory and analytical applications requiring contamination-free vacuum generation. Based on positive displacement via elastomeric diaphragm oscillation, the MVP-015-2 delivers reliable, pulsation-dampened suction without lubricants or hydrocarbon vapor carryover—ensuring absolute dryness and chemical inertness in the pumped gas stream. Its two-stage design achieves ultimate pressures down to 3.5 mbar (without gas ballast) and 4.5 mbar (with gas ballast), with a nominal pumping speed of 0.95 m³/h at atmospheric inlet pressure. The pump is optimized as a forepump for Pfeiffer’s HiPace and TurboVac turbomolecular pumps, and is widely integrated into surface area analyzers (e.g., Micromeritics ASAP series), residual gas analyzers, leak detection systems, and vacuum ovens where hydrocarbon-free operation is mandated by ISO 27401, ASTM E2912, or USP guidelines.

Key Features

• True oil-free operation: No lubricants contact the gas path—eliminating risk of sample contamination, oil backstreaming, or solvent degradation.
• Extended diaphragm service life: Reinforced EPDM or FKM diaphragms (model-dependent) withstand >10,000 operating hours under typical lab duty cycles.
• Ultra-low noise emission: Acoustic output of only 26.5 dB(A) enables installation in shared lab spaces without acoustic enclosures.
• Low vibration design: Precision-balanced motor and damped mounting minimize mechanical coupling to sensitive instrumentation (e.g., SEM stages, quartz crystal microbalances).
• Global power compatibility: Dual-voltage AC input (100–115 V / 208–236 V, 50/60 Hz) supports deployment across North America, EU, and APAC regions without external transformers.
• Modular maintenance: Diaphragms, valves, and gas ballast assemblies are field-replaceable using standard tools—no calibration required post-service.
• Robust housing: Die-cast aluminum body with IP54-rated enclosure ensures resistance to ambient dust and incidental splashes per IEC 60529.

Sample Compatibility & Compliance

The MVP-015-2 is compatible with non-condensable gases and low-vapor-pressure solvents (e.g., N₂, Ar, He, CO₂, CH₄, and trace organics below 10 Torr partial pressure). It is unsuitable for pumping corrosive vapors (e.g., HCl, Cl₂, NH₃) unless equipped with the C-version (MVP-015-4C) featuring fluoropolymer-coated internals. All MVP models comply with EU Machinery Directive 2006/42/EC, Electromagnetic Compatibility Directive 2014/30/EU, and RoHS 2011/65/EU. UL recognition (E350493) confirms conformity with UL 61010-1 for laboratory electrical equipment safety. When deployed in regulated environments (e.g., pharmaceutical QC labs), the pump supports audit-ready documentation packages aligned with FDA 21 CFR Part 11 requirements for instrument qualification (IQ/OQ/PQ).

Software & Data Management

While the MVP-015-2 operates as a standalone analog device, its electrical interface (IEC 60320 C14 inlet) and stable power draw enable seamless integration into automated vacuum control systems via programmable logic controllers (PLCs) or LabVIEW-based DAQ platforms. Optional analog 0–10 V or 4–20 mA feedback signals (available on select OEM configurations) permit real-time monitoring of motor current—serving as an indirect proxy for pump load and diaphragm wear. Pfeiffer’s Vacuum Manager software (v4.0+) supports remote status polling and event logging when paired with compatible vacuum gauges and controllers—facilitating GLP-compliant record retention and preventive maintenance scheduling.

Applications

• Forepumping for turbomolecular and sputter-ion pumps in UHV systems (10⁻⁷–10⁻⁹ mbar range).
• Vacuum degassing of solvents, resins, and polymer precursors prior to casting or spectroscopy.
• Gas evacuation in BET surface area and porosity analyzers (ASTM D3663, ISO 9277).
• Leak testing of hermetic packages using helium mass spectrometry (ASTM E493, ISO 10648-2).
• Sample preparation for XRD, XPS, and TEM—where carbon contamination from oil diffusion must be avoided.
• Process vacuum in gloveboxes and controlled-atmosphere reactors handling air-sensitive catalysts.

FAQ

Is the MVP-015-2 suitable for continuous 24/7 operation?
Yes—the pump is rated for continuous duty (S1 duty cycle) with thermal protection and automatic shutdown at >85°C winding temperature.
Can it handle water vapor or condensable vapors?
Limited tolerance only; prolonged exposure to high-humidity or condensable streams accelerates diaphragm fatigue. Use of a cold trap or gas ballast is recommended for intermittent moisture loads.
What maintenance intervals are recommended?
Diaphragm replacement every 8,000–12,000 operating hours; valve kits every 24 months or 6,000 hours—whichever occurs first—under typical lab usage.
Does it meet cleanroom compatibility standards?
Yes—particle shedding is 0.5 µm) per ISO 14644-1 Class 5 when installed with HEPA-filtered exhaust ducting and operated within specified ambient conditions.
Is remote monitoring supported out-of-the-box?
No native digital interface is included; however, analog signal outputs (optional) and standardized power consumption profiles allow integration with third-party SCADA or building management systems.
