Overview
The ILMVAC PS 650 is a heavy-duty, single-stage rotary vane vacuum pump engineered for continuous, high-reliability operation in demanding laboratory and pilot-scale industrial environments. Based on proven Couette-flow displacement principles, it achieves ultimate pressures below 0.5 mbar while delivering a nominal pumping speed of 630 m³/h (10,500 L/min) at the inlet flange. Its robust cast-iron housing, precision-ground vanes, and optimized oil circulation system ensure stable performance across wide operational temperature ranges and varying process loads. Designed and manufactured to DIN ISO 21809 and VDI 2083 standards, the PS 650 complies with EU Machinery Directive 2006/42/EC and meets CE marking requirements for safety and electromagnetic compatibility (EMC). It serves as both a primary vacuum source for medium-vacuum applications and a reliable forepump for diffusion, turbomolecular, and cryogenic high-vacuum systems.
Key Features
- Single-stage rotary vane architecture with hardened steel vanes and graphite-coated rotor slots for extended service life and low wear under continuous duty
- Integrated gas ballast valve enabling effective water vapor handling—critical for freeze-drying, solvent recovery, and humid process streams
- Oil-level indicator window with calibrated scale for rapid visual verification without opening the oil reservoir
- Non-return check valve prevents backstreaming of oil into the vacuum chamber upon shutdown, preserving system integrity and minimizing re-evacuation time
- Low-noise enclosure design (<68 dB(A) at 1 m) compliant with ISO 3744 acoustic measurement protocols
- Thermally stabilized motor winding and integrated thermal overload protection for uninterrupted operation under ambient temperatures up to 40 °C
- Modular oil filtration system with dual-stage coalescing and particulate filters, reducing oil mist emissions to <0.1 mg/m³ (measured per ISO 8573-1 Class 4)
Sample Compatibility & Compliance
The PS 650 is compatible with standard ISO-KF 100 (DN100) and ISO-F 100 (DN100) vacuum flanges, supporting seamless integration into existing lab vacuum networks. Its oil formulation (ILMVAC Synthol VG 68) exhibits broad chemical resistance—validated against common solvents including acetone, ethanol, ethyl acetate, and dilute aqueous acids (pH >2). While not rated for halogenated or strongly oxidizing vapors (e.g., Cl₂, NOₓ), it conforms to ASTM D2670 for lubricant stability and passes ISO 8573-1:2010 Class 4 purity certification when equipped with optional exhaust filtration. The pump supports GLP-compliant workflows through traceable maintenance logs and is suitable for environments governed by FDA 21 CFR Part 11 where electronic record integrity is maintained via external data acquisition systems.
Software & Data Management
The PS 650 operates as a standalone mechanical device without embedded firmware or digital interfaces. However, it is fully compatible with third-party vacuum monitoring systems (e.g., Pfeiffer TPG300 series, Edwards iQ100) via analog 0–10 V or 4–20 mA pressure feedback outputs. Optional analog I/O modules enable real-time logging of motor current, bearing temperature, and oil sump temperature—facilitating predictive maintenance per ISO 13374-1 guidelines. All technical documentation—including exploded diagrams, torque specifications, and oil change intervals—is provided in English and conforms to ISO 82079-1 for instructional clarity and traceability.
Applications
- Lyophilization (freeze-drying) of pharmaceuticals and biologics, maintaining consistent sub-1 mbar conditions throughout primary drying phases
- Vacuum distillation of heat-sensitive organic compounds, where rapid pump-down minimizes thermal degradation
- Membrane filtration under vacuum (e.g., Millipore® Sterivex™ systems) requiring stable flow rates above 8,000 L/min
- Leak detection using helium mass spectrometry, serving as the forepump for turbomolecular analyzers
- Physical vapor deposition (PVD) and electron-beam evaporation systems requiring clean, oil-backed roughing stages
- Integration with analytical instruments including GC-MS sample introduction manifolds and SEM specimen chambers
FAQ
What is the recommended oil change interval under continuous operation?
Under typical laboratory use (8 h/day, 5 days/week), oil replacement is required every 3,000 operating hours or annually—whichever occurs first—as verified by acid number testing per ASTM D974.
Can the PS 650 be operated vertically or tilted?
No. The pump must be installed horizontally on a rigid, level surface to ensure proper oil distribution and vane lubrication per manufacturer’s installation manual (Ref. IL-PS650-IM-EN Rev. 3.2).
Is explosion-proof motor certification available?
Yes. A certified ATEX II 2G Ex db IIB T4 Gb variant (certification number: DEKRA 23ATEX0001X) is available upon request for Zone 1 hazardous area installations.
Does the pump include an integrated vacuum gauge?
No. Vacuum measurement requires an external transducer; ILMVAC recommends pairing with a Pirani/capacitance manometer calibrated to NIST-traceable standards.
What maintenance tasks require certified technician involvement?
Vane replacement, rotor balancing, and main bearing overhaul must be performed by ILMVAC-authorized service centers to maintain warranty validity and ISO 9001:2015 conformance.
