GAST MOA-V111-CD Diaphragm Vacuum Pump

Overview

The GAST MOA-V111-CD is a compact, oil-free diaphragm vacuum pump engineered for reliable, low-maintenance operation in laboratory, medical, and environmental instrumentation applications. Utilizing a precision-machined PTFE-reinforced diaphragm and corrosion-resistant stainless steel valve assembly, it delivers consistent vacuum generation without internal lubrication—eliminating oil contamination risks and simplifying compliance with ISO 8573-1 Class 0 air purity requirements. Its operating principle relies on reciprocating diaphragm motion driven by an eccentric cam, enabling positive displacement of gas across sealed chambers. This architecture ensures stable performance under variable backpressure conditions and supports continuous duty cycles typical in analytical sample preparation, filtration, and gas sampling workflows.

Key Features

• Oil-free operation: Eliminates risk of sample or system contamination; compliant with USP and ISO 14644 cleanroom-compatible protocols when integrated into closed-loop systems.
• Low acoustic signature: Operates at ≤45 dBA at 1 m distance—suitable for noise-sensitive environments including clinical laboratories and shared research facilities.
• Robust thermal management: Integrated thermal cutoff and optimized motor winding design sustain stable output across ambient temperatures from 5 °C to 40 °C.
• Compact footprint: Dimensions of 193 × 108 × 121 mm (L × W × H) enable seamless integration into benchtop analyzers, portable gas monitors, and modular vacuum manifolds.
• Long service life: Rated for >20,000 hours MTBF under nominal load conditions; diaphragm replacement intervals exceed 12 months in typical lab filtration use.
• Electrical safety: UL Recognized (E151272) component rating; conforms to IEC 61000-6-3 (EMC emission) and IEC 61000-6-2 (immunity) standards.

Sample Compatibility & Compliance

The MOA-V111-CD is compatible with non-reactive, non-condensable gases and vapors commonly encountered in analytical chemistry and biomedical sampling—including ambient air, nitrogen, oxygen, CO₂, and diluted VOC mixtures. It is not rated for explosive, corrosive (e.g., Cl₂, NH₃), or solvent-saturated streams. When used in regulated environments, the pump supports GLP and GMP documentation requirements through traceable serial-numbered units and factory calibration records. Its oil-free design facilitates adherence to FDA 21 CFR Part 11–aligned data integrity practices when paired with validated vacuum monitoring software.

Software & Data Management

While the MOA-V111-CD operates as a standalone analog device, it is fully compatible with third-party vacuum control systems featuring 0–10 V or 4–20 mA analog feedback inputs. Integration with LabVIEW™, MATLAB® Data Acquisition Toolkits, or PLC-based SCADA platforms enables real-time vacuum level logging, duty-cycle optimization, and predictive maintenance alerts. Optional pressure transducers (e.g., Validyne DP15 series) can be mounted inline to generate time-stamped vacuum profiles compliant with ASTM D3985 (oxygen transmission rate testing) or ISO 15502 (vacuum drying validation).

Applications

• Laboratory filtration: Vacuum-assisted membrane filtration for water quality analysis (EPA Method 1600), particulate collection (ISO 7708), and microbiological assays.
• Medical diagnostics: Sample aspiration in hematology analyzers, blood gas monitors, and point-of-care respiratory gas analyzers.
• Environmental monitoring: Active sampling for ambient VOCs, NOₓ, and SO₂ using sorbent tubes per EPA TO-17 protocols.
• Instrument OEM integration: Primary vacuum source for mass spectrometer foreline pumps, FTIR gas cells, and headspace samplers.
• Process validation: Vacuum hold testing of sterile packaging per ISO 11607-2 and ASTM F2338.

FAQ

Is the MOA-V111-CD suitable for continuous-duty operation?
Yes—designed for uninterrupted 24/7 service under rated vacuum and flow conditions; thermal protection circuitry prevents overheating during extended use.
Can this pump handle condensable vapors?
No—it is not configured with vapor traps or condensate drainage; prolonged exposure to saturated steam or solvent vapors may compromise diaphragm integrity.
What is the expected diaphragm replacement interval?
Under standard lab filtration duty (≤30 min/h average runtime), diaphragms typically last ≥12 months; replacement kits (P/N: 111-0021) are field-serviceable in <15 minutes.
Does GAST provide calibration certificates for this model?
Factory calibration data (vacuum level vs. inlet pressure, flow vs. backpressure) is supplied with each unit; NIST-traceable certification is available upon request (additional lead time and fee apply).
Is the MOA-V111-CD compatible with 50 Hz power grids outside North America?
Yes—the 230 V, 50 Hz motor variant (MOA-V111-CD) is specifically engineered for European, Asian, and Middle Eastern utility standards and includes dual-voltage insulation rating per IEC 60034-1.
