Overview
The Vacuumer VOP 100 is a direct-drive, oil-lubricated rotary vane vacuum pump engineered for stable, continuous operation in demanding laboratory and light industrial environments. Based on the proven principles of positive displacement via rotating vanes within an eccentrically mounted rotor chamber, the VOP 100 achieves high volumetric efficiency and consistent ultimate vacuum performance. Its design integrates mechanical robustness with thermal management—featuring forced oil circulation and integrated air cooling—to sustain rated pumping speed across extended duty cycles. Unlike belt-driven alternatives, the direct-coupled motor eliminates slippage, reduces maintenance intervals, and enhances rotational stability, contributing to lower vibration transmission and improved system longevity. The pump is intended for primary vacuum generation in applications requiring base pressures in the 10⁻² Pa range, with optional gas ballast functionality enabling effective removal of condensable vapors during solvent-based processes.
Key Features
- Direct-coupled 400 W, 4-pole induction motor with dual-frequency compatibility (50/60 Hz), delivering 1430 rpm (50 Hz) or 1730 rpm (60 Hz) for optimized torque and speed consistency
- Integrated gas ballast valve for controlled admission of atmospheric air into the compression stage, facilitating vapor handling during freeze-drying or solvent evaporation without oil contamination
- Automatic anti-backflow check valve prevents reverse rotation and oil backstreaming upon shutdown, protecting downstream instrumentation
- Overload protection circuitry safeguards motor windings against thermal stress under high inlet pressure or prolonged low-vacuum operation
- Low-noise, low-vibration housing design incorporating precision-balanced rotor assembly and elastomeric mounting interface
- Forced oil lubrication system with COSMA-100 synthetic mineral oil (900 mL capacity), formulated for oxidative stability and low vapor pressure at elevated operating temperatures
Sample Compatibility & Compliance
The VOP 100 is compatible with standard ISO-KF (NW25) vacuum tubing and flange interfaces, enabling seamless integration with vacuum ovens, lyophilizers, mass spectrometers, electron microscopes, and thin-film deposition systems. It meets general-purpose vacuum requirements outlined in ASTM F2647 (Standard Guide for Vacuum System Performance Testing) and supports GLP-compliant workflows when paired with traceable pressure monitoring and log-enabled controllers. While not certified for explosive or corrosive process gases, its construction adheres to IEC 60034-1 (rotating electrical machines) and IEC 61000-6-3 (EMC emission limits). Oil change intervals are defined per ISO 8573-1 Class 4 particulate and Class 3 moisture specifications under typical lab usage conditions.
Software & Data Management
The VOP 100 operates as a standalone analog device without embedded digital controls or communication ports. For system-level monitoring, it is designed to interface with external vacuum gauges (e.g., Pirani, capacitance manometer, or cold cathode sensors) and programmable logic controllers (PLCs) via dry-contact status outputs (optional relay module available separately). When deployed in regulated environments, users may integrate its operational logs—including runtime hours and thermal alerts—into centralized LabVantage or Empower 3 platforms using third-party analog-to-digital signal converters compliant with FDA 21 CFR Part 11 audit trail requirements.
Applications
- Primary vacuum source for laboratory-scale freeze dryers and vacuum ovens used in pharmaceutical formulation and food science research
- Roughing pump for high-vacuum systems (e.g., turbomolecular or diffusion pumps) in surface analysis laboratories (XPS, AES)
- Process vacuum for physical vapor deposition (PVD) and sputtering setups in materials science labs
- Evacuation and degassing support in analytical instrumentation including GC-MS sample introduction manifolds and residual gas analyzers
- Industrial vacuum packaging and semiconductor wafer handling where oil-sealed reliability outweighs clean-dry requirements
FAQ
What type of oil is required for optimal performance?
COSMA-100 synthetic mineral oil is specified for use due to its low saturated vapor pressure (<1 × 10⁻⁴ Pa at 20 °C), thermal stability up to 120 °C, and compatibility with common elastomer seals.
Can the VOP 100 be operated continuously at ultimate vacuum?
Yes, provided ambient temperature remains within 7–40 °C and oil level and quality are verified every 500 operating hours or quarterly—whichever occurs first.
Is the pump suitable for pumping solvents like acetone or ethanol?
With the gas ballast valve fully open and appropriate condensation trapping upstream, short-term solvent exposure is permissible; however, prolonged operation with high vapor loads requires periodic oil replacement and inspection of vanes and stator surfaces.
Does the VOP 100 include a vacuum gauge or controller?
No—vacuum measurement and control must be implemented externally using calibrated transducers and PID-capable instrumentation.
What safety certifications does the VOP 100 carry?
It complies with CE marking requirements under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU, with conformity verified by a Notified Body in South Korea.
