ILMVAC MPC 105 E Chemically Resistant Single-Stage Diaphragm Vacuum Pump (<75 mbar Ultimate Pressure)

Overview

The ILMVAC MPC 105 E is a compact, single-stage diaphragm vacuum pump engineered for precision and long-term reliability in chemically aggressive laboratory environments. Unlike oil-lubricated or water-ring vacuum systems, this pump operates dry—eliminating contamination risks, oil backstreaming, and consumable dependency. Its core operating principle relies on reciprocating PTFE-coated diaphragms driven by an eccentric cam mechanism, generating vacuum through positive displacement without internal lubrication. Designed to achieve an ultimate pressure of <60 mbar (abs), the MPC 105 E delivers stable, pulse-dampened vacuum output ideal for continuous-duty applications requiring chemical inertness and low maintenance overhead. It complies with IEC 61000-6-3 (EMC emission standards) and meets CE marking requirements for laboratory equipment within the European Economic Area.

Key Features

• Chemical resistance certified: All gas-contact surfaces—including diaphragm, valve plates, chamber housing, and inlet/outlet ports—are fully coated with polytetrafluoroethylene (PTFE) and reinforced with carbon fiber composite for enhanced mechanical stability and corrosion resilience.
• Three-layer diaphragm construction: A proprietary sandwich design integrates elastomeric base layers with a central PTFE barrier, significantly extending service life under cyclic stress and preventing permeation of aggressive vapors (e.g., HCl, HF, organic solvents).
• Dry, oil-free operation: No lubricants, seals, or cooling fluids required—ensuring zero risk of sample contamination and eliminating routine oil changes or disposal concerns.
• Low power consumption & thermal management: Optimized motor winding and aluminum alloy housing provide efficient heat dissipation, enabling uninterrupted operation at ambient temperatures up to 40 °C.
• Integrated vibration damping: Rubber-isolated mounting feet and balanced drive train reduce transmitted vibration to <0.5 mm/s RMS, critical for sensitive analytical setups such as gravimetric dryers or connected mass spectrometry interfaces.
• Modular service architecture: Field-replaceable diaphragm kits, valve assemblies, and motor modules allow full functional restoration without specialized tools or factory recalibration.

Sample Compatibility & Compliance

The MPC 105 E is compatible with vapors and gases commonly encountered in synthetic chemistry, pharmaceutical processing, and materials science workflows—including chlorinated hydrocarbons, alcohols, esters, ketones, and acidic fumes (pH ≥1). It is not rated for explosive atmospheres (ATEX), halogenated peroxides, or particulate-laden streams without upstream filtration. The pump conforms to ISO 8573-1:2010 Class 0 (oil-free air standard) for compressed gas purity and supports GLP-compliant documentation when integrated into validated vacuum systems. While not intrinsically safe, its design facilitates integration into fume hood exhaust manifolds or closed-loop solvent recovery trains meeting EN 14175-3 ventilation safety guidelines.

Software & Data Management

As a standalone analog-controlled pump, the MPC 105 E does not feature digital connectivity or embedded firmware. However, it is fully compatible with external vacuum controllers (e.g., Vacuubrand VACUU·SELECT or KNF EC series) via 0–10 V analog input/output interfaces. When deployed in regulated environments, users may log operational parameters—including runtime hours, on/off cycles, and duty cycle—using third-party SCADA or LIMS platforms compliant with FDA 21 CFR Part 11 requirements. Maintenance records, including diaphragm replacement dates and performance verification data (e.g., ultimate pressure checks per ISO 21360-1 Annex B), are recommended for audit readiness under ISO/IEC 17025 or GMP Annex 15 frameworks.

Applications

• Vacuum distillation of thermally labile compounds where oil contamination must be avoided
• Continuous evacuation of jacketed reactors during exothermic synthesis under inert atmosphere
• Filter flask aspiration in analytical sample preparation (e.g., EPA Method 505, ASTM D892)
• Rotary evaporation support for high-boiling-point solvents (e.g., DMF, DMSO) without condenser icing
• Desiccator cabinet evacuation for moisture-sensitive hygroscopic standards (e.g., USP Reference Standards)
• Pre-vacuum conditioning of porous materials prior to BET surface area analysis (ISO 9277)

FAQ

What is the maximum allowable inlet vapor concentration for safe operation?
The MPC 105 E is designed for non-condensable gases and low-saturation vapors. For condensable solvents, inlet cold traps are strongly recommended; maximum permissible partial pressure should remain below 20% of the solvent’s vapor pressure at pump head temperature.
Can this pump be used in a cleanroom environment?
Yes—its dry, particle-free operation and absence of outgassing lubricants make it suitable for ISO Class 5–7 cleanrooms when installed with HEPA-filtered exhaust ducting and grounded static discharge paths.
How often should the diaphragm be replaced under continuous use?
Under typical laboratory conditions (8 h/day, moderate solvent load), PTFE-carbon diaphragms exhibit service life exceeding 10,000 hours; replacement intervals should be verified annually via ultimate vacuum test per manufacturer’s procedure.
Is the pump compatible with vacuum gauges using Pirani or capacitance manometer sensors?
Yes—the MPC 105 E interfaces seamlessly with all common analog and digital vacuum measurement systems, provided electrical isolation and proper signal scaling are maintained per gauge manufacturer specifications.
