Overview
The ILMVAC PS 20 is a precision-engineered single-stage rotary vane vacuum pump designed for reliable, continuous operation in demanding laboratory and light industrial environments. Based on the classic Couette-type positive displacement principle, it achieves vacuum generation through synchronized rotation of vanes within an eccentrically mounted rotor, creating variable-volume chambers that compress and expel gas toward the exhaust. With a guaranteed ultimate pressure of <1.0 mbar (≤100 Pa) and a nominal pumping speed of 18.0 m³/h (300 L/min), the PS 20 delivers stable base vacuum performance suitable for applications requiring moderate vacuum levels—particularly where rapid pump-down time, chemical resilience, and operational robustness are critical. Its compact footprint, low acoustic emission (<52 dB(A)), and integrated oil management system reflect decades of German engineering refinement in rotary vane technology.
Key Features
- Single-stage rotary vane architecture with hardened steel vanes and precision-ground aluminum housing for extended service life and dimensional stability
- Integrated gas ballast valve enabling effective handling of condensable vapors—including water vapor—without oil emulsification or performance degradation
- Optimized oil circulation path with non-return check valve preventing backstreaming of oil into the vacuum chamber upon shutdown
- Translucent oil-level sight window with calibrated markings for real-time visual monitoring under ambient lighting conditions
- Low-oil-fog design compliant with ISO 8573-1 Class 4 particulate specifications, minimizing contamination risk in adjacent instrumentation
- Thermally stabilized motor housing with IP54-rated enclosure, rated for continuous 220 V / 50 Hz operation with thermal overload protection
- Modular mounting configuration supporting both horizontal and vertical installation; includes integrated anti-vibration feet and M6 threaded ports
Sample Compatibility & Compliance
The PS 20 is compatible with a broad spectrum of non-corrosive and mildly aggressive process gases encountered in routine laboratory workflows—including air, nitrogen, argon, water vapor, and low-concentration organic solvent vapors. It is not intended for use with halogenated solvents, strong oxidizers (e.g., Cl₂, O₃), or highly polymerizing monomers. The pump meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU. Oil-lubricated operation complies with ISO 21360-1:2021 for volumetric vacuum pump performance verification. While not certified for ATEX or IECEx hazardous area use, its low surface temperature rise (<45 K above ambient) and absence of sparking components support safe deployment in general-purpose lab zones per IEC 61000-6-2/6-3.
Software & Data Management
As a standalone mechanical vacuum source, the PS 20 operates without embedded firmware or digital control interfaces. All operational parameters—including inlet pressure, oil temperature, and runtime—are monitored via analog indicators and manual service logs. For integration into automated systems, optional analog pressure transducer outputs (0–10 V or 4–20 mA) can be retrofitted at the inlet port to feed vacuum level data into external PLCs or SCADA platforms. Maintenance records—including oil change intervals (recommended every 3,000 operating hours or annually), filter replacement, and bearing inspection—align with GLP documentation standards and support audit readiness per ISO/IEC 17025:2017 Clause 6.4.2.
Applications
- Primary vacuum source for freeze-drying (lyophilization) of biological samples and pharmaceutical formulations
- Pre-evacuation stage for rotary evaporators and short-path distillation units operating down to 1–10 mbar
- Support pump for diffusion pumps, turbomolecular pumps, and cryopumps in high-vacuum systems
- Vacuum-assisted filtration in analytical sample preparation (e.g., SPE, membrane filtration)
- Leak testing of sealed enclosures and packaging integrity validation per ASTM E493
- Thin-film deposition processes including thermal evaporation and sputtering where base pressure ≤1 mbar is sufficient
- Integration with mass spectrometry sample introduction systems requiring stable roughing vacuum
FAQ
What is the recommended oil type for the PS 20?
ILMVAC specifies ISO VG 68 mineral-based vacuum pump oil (e.g., ILMVAC VP-Oil 68 or equivalent). Synthetic alternatives must meet DIN 51506 VDL specifications and demonstrate compatibility with nitrile elastomer seals.
Can the PS 20 be operated continuously for 24/7 applications?
Yes—provided ambient temperature remains between 10–35 °C, ventilation is unobstructed, and scheduled maintenance intervals are strictly observed per the technical manual.
Is the PS 20 suitable for pumping corrosive gases?
No. It is engineered for non-corrosive and mildly aggressive media only. For chlorine, HF, or ammonia service, consult ILMVAC’s chemically resistant PK series with fluorocarbon-coated internals.
Does the pump include an exhaust filter?
A standard oil mist separator is factory-installed; optional activated carbon exhaust filters are available for VOC abatement in confined lab spaces.
What is the warranty period and service support coverage?
ILMVAC provides a 24-month limited warranty covering material and workmanship defects; authorized service centers in the EU, US, and APAC regions offer calibration, overhaul, and spare parts logistics.
