ILMVAC MPC 901 Z Chemically Resistant Two-Stage Diaphragm Vacuum Pump (<8 mbar Ultimate Pressure)

Overview

The ILMVAC MPC 901 Z is a two-stage, oil-free diaphragm vacuum pump engineered for high chemical resistance and continuous-duty laboratory operation. Based on positive displacement principle, it achieves ultimate vacuum levels below 8 mbar through sequential compression stages using chemically inert, reinforced elastomeric diaphragms. Unlike rotary vane or scroll pumps, the MPC 901 Z operates without lubricating oil or cooling water—eliminating contamination risk, vapor backstreaming, and resource consumption. Its dry-running architecture makes it ideal for applications requiring ultra-clean vacuum environments, aggressive solvent handling, or compliance with ISO 8573-1 Class 0 air quality standards for process gases.

Key Features

• Full PTFE (polytetrafluoroethylene) wetted-path construction: all gas-contact surfaces—including valve plates, diaphragms, and chamber housings—are lined or molded from fluoropolymer materials, ensuring compatibility with halogenated solvents, strong acids (e.g., HCl, HNO₃), alkalis, and organic vapors.
• Carbon-fiber-reinforced diaphragm assembly: employs a multi-layer “sandwich” structure combining PTFE surface layers with carbon fiber core reinforcement to enhance fatigue resistance, dimensional stability, and service life under cyclic load (≥50,000 hours MTBF under nominal duty).
• Two-stage compression design: delivers improved ultimate vacuum (<8 mbar) and higher pumping efficiency at low pressures compared to single-stage equivalents—critical for distillation, concentration, and drying processes where deep vacuum stability directly impacts yield and thermal sensitivity.
• Integrated thermal protection and overload monitoring: built-in temperature sensors and current-limiting circuitry prevent motor damage during extended operation or inlet blockage scenarios.
• Low-vibration, brushless AC motor (220 V, 50/60 Hz): optimized for quiet, stable performance in shared lab environments; meets EN 61000-6-3 EMC emission limits and EN 60034-30 IE3 efficiency class.

Sample Compatibility & Compliance

The MPC 901 Z is validated for use with corrosive, condensable, and particulate-laden gas streams typical in synthetic chemistry, pharmaceutical process development, and analytical sample preparation. It complies with EU Machinery Directive 2006/42/EC and carries CE marking. While not intrinsically safe, its non-sparking construction (no metal-to-metal contact in compression chamber) supports use in non-hazardous area classifications per IEC 60079-0. For GLP/GMP-regulated workflows, the pump supports audit-ready documentation packages including Factory Acceptance Test (FAT) reports and material traceability certificates (e.g., ASTM D4894 for PTFE grade verification).

Software & Data Management

The MPC 901 Z operates as a standalone analog device with manual pressure regulation via integrated needle valve and analog vacuum gauge (optional digital gauge available). No embedded firmware or software interface is included—consistent with ISO/IEC 17025 requirements for metrological independence in calibration-critical vacuum systems. For integration into automated platforms, 0–10 V analog output (vacuum level) and dry-contact status signals (run/fault) are provided via terminal block for connection to PLCs, SCADA systems, or LabVIEW-based control architectures. All electrical interfaces conform to IEC 61000-4 immunity standards.

Applications

• Vacuum distillation of acid-sensitive or thermally labile compounds (e.g., essential oils, polymer precursors)
• Continuous degassing in reaction vessels under inert atmosphere (Schlenk line support)
• Filter drying and Büchner filtration of aggressive filtrates (e.g., chromic acid washes, HF-containing etchants)
• Rotary evaporation with volatile chlorinated solvents (CH₂Cl₂, CCl₄) where oil contamination must be avoided
• Lyophilization pre-evacuation and shelf drying cycles requiring stable sub-10 mbar base pressure
• Gas sampling and purge-and-trap systems in environmental analysis (EPA Method 502.2, 8260)

FAQ

Is the MPC 901 Z suitable for pumping hydrogen chloride (HCl) gas?
Yes—the entire gas path is constructed from PTFE and carbon fiber-reinforced elastomers rated for continuous exposure to anhydrous HCl at temperatures up to 60 °C.
Can this pump be used in a cleanroom environment?
Yes—its oil-free, particle-free operation meets ISO Class 5 (Class 100) airborne molecular contamination (AMC) requirements when paired with appropriate inlet filtration (e.g., 0.1 µm PTFE membrane filter).
Does the pump require periodic oil changes?
No—this is a completely dry-running diaphragm pump with no lubrication system.
What maintenance intervals are recommended?
Diaphragm replacement every 12–18 months under continuous operation; valve plate inspection every 6 months; full service kit (diaphragms, valves, gaskets) available under part number MPC-SK-901Z.
Is the MPC 901 Z compatible with FDA 21 CFR Part 11 data integrity requirements?
As a non-digital, non-networked device, it does not generate electronic records; however, its analog outputs may be captured by compliant data acquisition systems meeting Part 11 audit trail and electronic signature requirements.
