ILMVAC MP 1201 T Three-Stage Diaphragm Vacuum Pump, Non-Chemically Resistant, Ultimate Vacuum <2 mbar

Overview

The ILMVAC MP 1201 T is a three-stage, oil-free diaphragm vacuum pump engineered for reliable, clean, and maintenance-efficient operation in general laboratory vacuum applications. Utilizing a dry-running, multi-stage diaphragm compression principle, it achieves an ultimate vacuum of <2 mbar without lubricants or hydrocarbon contamination—making it ideal for processes requiring inert, particle-free vacuum environments. Unlike rotary vane or scroll pumps, the MP 1201 T operates without internal oil, eliminating risk of backstreaming, vapor carryover, or sample cross-contamination. Its robust aluminum alloy housing and precision-machined PTFE-reinforced diaphragms ensure long-term dimensional stability and consistent performance under continuous duty cycles. Designed and assembled in Germany to DIN EN ISO 9001-certified manufacturing standards, the pump complies with CE marking requirements and meets electromagnetic compatibility (EMC) directives per EN 61326-1.

Key Features

• Three-stage diaphragm architecture for enhanced compression ratio and improved ultimate vacuum (<2 mbar)
• Oil-free, dry-running operation ensures zero hydrocarbon emission and eliminates need for oil changes or filter replacements
• Integrated thermal protection and overload shutdown safeguard motor integrity during extended operation
• Low-vibration, brushless AC motor (220 V, 50/60 Hz) with high-efficiency winding and IP54-rated enclosure
• Compact footprint (W × D × H: 320 × 370 × 310 mm) and lightweight design (32.8 kg) facilitate benchtop integration and mobility
• Chemically inert wetted materials: PTFE-coated diaphragms, EPDM valves, and stainless steel pump head—suitable for non-aggressive gases only

Sample Compatibility & Compliance

The MP 1201 T is explicitly rated for non-corrosive, non-condensable, and non-particulate gas streams—including ambient air, nitrogen, argon, and helium. It is not compatible with solvents, acidic vapors (e.g., HCl, HF), halogenated compounds, or oxidizing agents (e.g., O₃, NO₂), as these may degrade diaphragm elastomers or valve seals. The pump conforms to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions) standards. While not certified for ATEX or IECEx hazardous area use, its design supports GLP-compliant documentation workflows when paired with validated vacuum control systems. It is routinely deployed in laboratories adhering to ISO/IEC 17025 quality management systems for testing and calibration.

Software & Data Management

The MP 1201 T operates as a standalone analog device with no embedded digital interface or firmware. However, it integrates seamlessly with third-party vacuum controllers (e.g., VAT, Pfeiffer, or MKS analog-input modules) via 0–10 V or 4–20 mA process signals for closed-loop pressure regulation. When used in validated environments, its operational parameters—including runtime hours and thermal event logs—can be recorded manually or via external PLC-based SCADA systems compliant with FDA 21 CFR Part 11 requirements (when paired with audit-trail-capable software). No proprietary drivers or cloud connectivity are required or supported.

Applications

• Vacuum distillation of heat-sensitive organic compounds where oil contamination must be avoided
• Evacuation of jacketed glass reactors during controlled synthesis under reduced pressure
• Filter flask evacuation in qualitative and quantitative gravimetric filtration (e.g., ASTM D2986, ISO 12103-1)
• Routine solvent removal in rotary evaporation systems with cold trap integration
• Desiccation of hygroscopic samples in vacuum ovens operating down to 10 mbar range
• Support vacuum for freeze-dryer primary drying stages when paired with appropriate condenser capacity

FAQ

Is the MP 1201 T suitable for pumping corrosive or solvent-laden vapors?
No. This pump is strictly intended for non-corrosive, non-condensable gases. Exposure to aggressive chemicals will compromise diaphragm integrity and void warranty.
What is the expected service life under continuous operation?
With proper ventilation and ambient temperature ≤35 °C, typical diaphragm service life exceeds 10,000 operating hours; replacement kits (diaphragms, valves, gaskets) are available as genuine ILMVAC spare parts.
Can it be mounted vertically or on a mobile cart?
Yes—the pump is designed for flexible orientation and includes threaded mounting holes on base and rear panel; vibration-damping feet are factory-installed.
Does it meet noise emission limits for ISO 14001-certified laboratories?
At 62 dB(A) @ 1 m (per ISO 3744), it complies with standard laboratory acoustic requirements and requires no additional sound enclosure.
Is calibration documentation provided with shipment?
A factory test report verifying ultimate vacuum (<2 mbar) and suction speed (8.3 m³/h ±5%) is included; full metrological calibration per ISO/IEC 17025 is available upon request through accredited service partners.
