Overview
The ILMVAC P 12 E is a single-stage rotary vane vacuum pump engineered for reliable, continuous operation in demanding laboratory and light industrial environments. Based on proven Couette-flow displacement principles, it achieves ultimate vacuum levels down to 9 × 10−2 mbar while delivering a nominal pumping speed of 11.0 m³/h (183.3 L/min) at the inlet. Designed and manufactured to German engineering standards, the P 12 E integrates precision-machined rotor assemblies, hardened vanes, and optimized oil circulation pathways—ensuring stable performance across extended duty cycles. Its compact footprint (W × D × H ≈ 340 × 165 × 270 mm) and low mass (29.0 kg) support flexible integration into fume hoods, glove boxes, or modular vacuum systems without requiring structural anchoring.
Key Features
- Hermetically sealed, oil-lubricated rotary vane architecture with integrated anti-backstreaming valve—prevents oil migration into vacuum chambers upon shutdown
- Optimized vane geometry and surface-hardened rotor shaft enabling high volumetric efficiency and minimal internal leakage
- Integrated sight glass with calibrated oil-level indicator for rapid visual verification of lubricant volume and condition
- Low-noise operation (<62 dB(A) at 1 m), achieved via balanced rotating assembly, acoustic-dampening housing, and vibration-isolating feet
- Enhanced water vapor tolerance through thermally stabilized exhaust gas routing and high-flash-point mineral oil formulation
- Chemical resistance upgrade option available via fluorocarbon-compatible gasket sets (FKM/Viton®) and corrosion-resistant internal coatings
- Oil mist separator standard—reduces airborne hydrocarbon emissions to <0.5 mg/m³ under continuous operation
Sample Compatibility & Compliance
The P 12 E is compatible with non-reactive, non-polymerizing gases and vapors commonly encountered in analytical and preparative vacuum applications—including water, ethanol, acetone, and ethyl acetate. It is not rated for use with halogenated solvents, strong oxidizers (e.g., nitric acid vapor), or condensable organosilicons without optional cold trap integration. The pump complies with EU Machinery Directive 2006/42/EC, Electromagnetic Compatibility Directive 2014/30/EU, and RoHS 2011/65/EU. While not intrinsically safe, it may be deployed in Zone 2 classified areas when installed per IEC 60079-14 guidelines. Oil service intervals are defined per ISO 8573-1 Class 4 (solid particles) and Class 3 (oil aerosol) requirements.
Software & Data Management
As a standalone mechanical vacuum source, the P 12 E operates without embedded firmware or digital interfaces. However, it is fully compatible with third-party vacuum monitoring systems via analog 0–10 V or 4–20 mA pressure feedback signals when paired with optional capacitance manometers (e.g., MKS Baratron® series). Maintenance logs—including oil change dates, operating hours, and observed ultimate pressure trends—can be recorded in laboratory information management systems (LIMS) compliant with GLP and FDA 21 CFR Part 11 audit-trail requirements. ILMVAC provides traceable calibration certificates for optional integrated pressure transducers upon request.
Applications
- Primary vacuum source for freeze-drying (lyophilization) of biological samples and pharmaceuticals
- Pre-vacuum stage for diffusion pumps, turbomolecular pumps, and cryopumps in high-vacuum systems
- Continuous evacuation during rotary evaporation and short-path distillation
- Vacuum-assisted filtration in chemical synthesis and environmental sample preparation
- Leak testing of sealed enclosures using pressure-rise or helium sniffing methodologies
- Thin-film deposition support in sputtering and thermal evaporation setups
- Integration with mass spectrometers, electron microscopes, and residual gas analyzers as roughing pump
FAQ
What is the recommended oil type and replacement interval?
ILMVAC specifies ISO VG 32 mineral oil (e.g., ILMVAC VP 32 or equivalent) with a typical service life of 3,000 operating hours or 12 months—whichever occurs first—under clean, dry gas load conditions.
Can the P 12 E handle corrosive process gases?
Standard configuration supports mild organic vapors; for aggressive media (e.g., HCl, Cl₂), specify FKM seals and optional stainless-steel exhaust valve components at time of order.
Is an exhaust filter required for indoor laboratory use?
Yes—an oil mist filter is factory-installed and must remain in place to meet occupational exposure limits (OELs) for hydrocarbon aerosols per ACGIH TLV® guidelines.
Does the pump include thermal overload protection?
Yes—the motor incorporates Class F insulation and bimetallic thermal cutout rated for ambient temperatures up to 40°C.
How is ultimate vacuum verified during commissioning?
Using a calibrated Pirani or capacitance manometer connected directly to the pump inlet port, after 30 minutes of continuous operation at ambient temperature and zero gas load.
