ILMVAC MP 055 Z (MP 054 Zp) Dual-Stage Diaphragm Vacuum Pump – Ultimate Vacuum <5 mbar, Chemically Non-Resistant

Overview

The ILMVAC MP 055 Z (also designated MP 054 Zp) is a compact, dual-stage diaphragm vacuum pump engineered for reliable, oil-free operation in general laboratory environments. Unlike rotary vane or scroll pumps, this pump operates on positive displacement via elastomeric diaphragms driven by an eccentric mechanical linkage—eliminating lubricants, hydrocarbon contamination, and vapor backstreaming. Its ultimate vacuum performance of <5 mbar (absolute) is achieved through two sequential compression stages, enabling efficient evacuation across moderate vacuum ranges (1000–5 mbar). Designed strictly for non-corrosive, dry, and chemically inert gases—including air, nitrogen, argon, and helium—the MP 055 Z complies with IEC 61000-6-3 (EMC) and IEC 60335-1 (safety) standards for laboratory-grade electrical equipment. It is not rated for solvent vapors, acidic gases (e.g., HCl, NO₂), halogenated compounds, or condensable vapors; exposure to such media will degrade diaphragm integrity and compromise long-term sealing performance.

Key Features

• Oil-free, dry-running architecture ensures zero hydrocarbon emission—critical for GC sample introduction, mass spectrometry prep, and analytical workflows requiring ultra-clean vacuum paths.
• Dual-stage design delivers enhanced compression ratio and faster pump-down times compared to single-stage equivalents, particularly below 50 mbar.
• Integrated thermal protection and overload cut-off prevent motor damage during extended duty cycles or inlet blockage events.
• Low vibration and acoustic signature (<52 dB(A)) enable benchtop deployment adjacent to sensitive instrumentation (e.g., balances, interferometers).
• Modular diaphragm head assembly allows field-replacement of diaphragms, valves, and seals without specialized tools—reducing mean time to repair (MTTR) to under 20 minutes.
• CE-marked and RoHS-compliant construction meets EU regulatory requirements for laboratory equipment placed on the market after 2021.

Sample Compatibility & Compliance

The MP 055 Z is validated exclusively for use with non-aggressive, non-condensable gases at ambient temperature and pressure. It is incompatible with vapors from organic solvents (e.g., acetone, ethanol, chloroform), corrosive gases (H₂S, Cl₂, NH₃), oxidizers (O₃, NOₓ), or particulate-laden streams. For applications involving trace solvent carryover (e.g., vacuum filtration of aqueous/organic mixtures), installation of a cold trap or chemical adsorption filter (e.g., activated charcoal or molecular sieve) upstream of the pump inlet is mandatory. The pump conforms to ISO 8573-1:2010 Class 4 purity for compressed air (adapted for vacuum service), and its materials—EPDM diaphragms, stainless steel valve plates, and PTFE-coated housing surfaces—meet USP Class VI biocompatibility requirements for incidental contact with pharmaceutical process environments.

Software & Data Management

This analog-controlled pump does not incorporate digital interfaces, firmware, or embedded software. All operational parameters—including power state, runtime hours (via optional external hour meter), and thermal status—are monitored manually. As a result, it requires no cybersecurity configuration, firmware updates, or audit trail generation. This absence of digital control aligns with GLP/GMP Annex 11 and FDA 21 CFR Part 11 principles for “simple devices”: validation focuses solely on mechanical performance verification (e.g., ultimate vacuum attainment, suction speed repeatability over 100 cycles) rather than software qualification. Documentation includes factory calibration certificates traceable to PTB (Physikalisch-Technische Bundesanstalt) standards.

Applications

• Vacuum distillation setups operating above 10 mbar, where precise pressure control supports fractional separation of low-boiling-point compounds.
• Reaction vessel evacuation prior to inert gas purging in Schlenk-line–compatible synthesis protocols.
• Gravity-assisted or pressure-driven vacuum filtration using Büchner or Hirsch funnels with polypropylene or glass frits.
• Rotary evaporation support for aqueous or high-polarity solvent removal (when paired with a condenser and chilled recirculator).
• Desiccator evacuation for moisture-sensitive reagents, standards, or reference materials stored under controlled low-humidity conditions.

FAQ

Is the MP 055 Z suitable for pumping solvent vapors?
No. Solvent vapors will swell EPDM diaphragms, accelerate valve fatigue, and cause irreversible loss of ultimate vacuum. Always use a condenser or adsorber trap when handling volatile organics.
Can this pump be mounted vertically?
Yes—provided the exhaust outlet remains unobstructed and ambient temperature stays within 10–40 °C. Avoid mounting directly above heat-generating instruments.
What maintenance intervals are recommended?
Diaphragm and valve replacement every 6,000 operating hours or 18 months (whichever occurs first); visual inspection of inlet filter monthly.
Does the pump include a vacuum gauge?
No. A separate analog or digital vacuum gauge (e.g., Pirani or capacitance manometer) must be installed in the vacuum line for pressure monitoring.
Is the MP 055 Z compatible with continuous-duty operation?
Yes—its IP20-rated induction motor and thermally stabilized stator winding support uninterrupted 24/7 operation under load, provided ambient airflow is unrestricted and inlet pressure remains >100 mbar during startup.
