ILMVAC MP 601 E Single-Stage Diaphragm Vacuum Pump, Non-Chemically Resistant, Ultimate Vacuum <75 mbar

Overview

The ILMVAC MP 601 E is a single-stage, oil-free diaphragm vacuum pump engineered for reliable, clean, and maintenance-efficient operation in laboratory environments. Designed according to DIN EN ISO 8573-1 Class 0 (oil-free air) standards, it generates vacuum via positive displacement using a PTFE-coated elastomeric diaphragm driven by an eccentric mechanical linkage. This dry-running principle eliminates lubricant contamination risks—critical for applications involving solvent vapors, moisture-sensitive samples, or analytical instrumentation requiring particle- and hydrocarbon-free vacuum streams. With an ultimate vacuum of <75 mbar (absolute) and a nominal suction speed of 3.8 m³/h (63.3 L/min), the MP 601 E delivers stable vacuum performance across variable load conditions, making it suitable for moderate-vacuum processes where chemical resistance to aggressive media is not required.

Key Features

• Oil-free, dry-running operation ensures zero risk of oil backstreaming or sample contamination
• Compact footprint (280 × 140 × 260 mm) and lightweight design (11.2 kg) enable flexible benchtop integration
• Brushless AC motor with thermal protection provides extended service life and consistent rotational stability
• Integrated pressure relief valve prevents overpressure during sudden flow restriction or system shutdown
• PTFE-reinforced diaphragm and stainless steel valve plates ensure long-term mechanical durability under cyclic stress
• Low-noise operation (<52 dB(A)) supports use in shared laboratory spaces without acoustic shielding
• Front-panel vacuum gauge port (¼” BSP) allows direct connection of analog or digital vacuum sensors

Sample Compatibility & Compliance

The MP 601 E is rated for continuous duty with non-corrosive, non-condensable, and non-particulate gases—including ambient air, nitrogen, argon, and low-concentration organic vapors (e.g., ethanol, acetone, hexane). It is explicitly not rated for halogenated solvents (e.g., chloroform, DCM), strong acids (HCl, HNO₃), alkalis (NaOH vapor), or oxidizing agents (O₃, NO₂). The pump complies with EU Machinery Directive 2006/42/EC, EMC Directive 2014/30/EU, and RoHS 2011/65/EU. Its construction meets GLP-relevant traceability requirements when used within validated vacuum systems; however, it does not include built-in audit trail or 21 CFR Part 11-compliant electronic records—integration with external data loggers is recommended for regulated workflows.

Software & Data Management

The MP 601 E operates as a standalone analog device with no embedded firmware, touchscreen interface, or digital communication ports (e.g., RS-232, USB, or Ethernet). Vacuum level monitoring and process control must be implemented externally via third-party pressure transducers (e.g., capacitance manometers or piezoresistive gauges) connected to laboratory data acquisition systems (e.g., LabVIEW, MATLAB, or SCADA platforms). For routine QC documentation, users commonly pair the pump with calibrated analog gauges and manual logbooks aligned with ISO/IEC 17025 internal audit protocols. Optional accessories include vibration-damping feet and inlet particulate filters (5 µm rating) to extend diaphragm service intervals.

Applications

• Vacuum distillation of thermally labile compounds under reduced pressure
• Evacuation of jacketed glass reactors prior to inert gas purging or reaction initiation
• Filtration support for Büchner funnels and sintered glass crucibles in solid–liquid separation
• Concentration of aqueous or organic extracts in rotary evaporators (as auxiliary or secondary pump)
• Drying of hygroscopic solids, lyophilized intermediates, or polymer films in vacuum ovens
• Sample preparation for FTIR, XRD, or SEM—where hydrocarbon-free vacuum preserves surface integrity
• Gas evacuation in glovebox antechambers during material transfer protocols

FAQ

Is the MP 601 E suitable for pumping acidic or halogenated vapors?
No. It is strictly intended for non-corrosive gases. Exposure to HCl, HF, Cl₂, or chlorinated solvents will degrade the diaphragm and valve seals. For such applications, consider chemically resistant variants with EPDM/FKM diaphragms or perfluoroelastomer-lined housings.
What is the expected service life of the diaphragm under continuous operation?
At rated duty cycle (≤8 h/day, ambient temperature ≤30 °C, clean inlet air), the PTFE-coated diaphragm typically lasts 10,000–15,000 operating hours before replacement—subject to periodic visual inspection for cracking or bulging.
Can this pump be used as a backing pump for turbomolecular or diffusion pumps?
No. Its ultimate vacuum limit (<75 mbar) is insufficient to support high-vacuum stages requiring foreline pressures below 10⁻² mbar. It is designed for roughing and medium-vacuum applications only.
Does the MP 601 E require regular oil changes or lubrication?
None. As a dry-running diaphragm pump, it contains no oil reservoirs, gearboxes, or sliding bearings requiring scheduled lubrication.
Is CE marking affixed and documented for this unit?
Yes. Each MP 601 E ships with a Declaration of Conformity (DoC) referencing harmonized EN standards and bears the CE mark on the nameplate per EU regulatory requirements.
