Vacuumer VOP 60 Direct-Drive Rotary Vane Vacuum Pump

Overview

The Vacuumer VOP 60 is a compact, direct-drive 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 eccentric stator chamber, the VOP 60 achieves high volumetric efficiency and consistent ultimate vacuum performance—reaching 6.7 × 10⁻² Pa (5 × 10⁻⁴ Torr) under standard conditions. Its oil-lubricated design ensures reliable sealing between vanes and cylinder walls, minimizing backstreaming and supporting reproducible vacuum levels across extended duty cycles. The integrated gas ballast valve enables controlled admission of atmospheric gas during pumping of condensable vapors—critical for applications involving solvents or moisture-laden process streams. Built-in anti-backflow check valves prevent oil migration into vacuum lines upon shutdown, enhancing system integrity and reducing maintenance frequency.

Key Features

• Direct-coupled motor architecture eliminates belt slippage and alignment issues, delivering precise speed control and improved mechanical longevity.
• Thermally stabilized housing with forced oil circulation and finned cooling surfaces maintains optimal operating temperature (7–40 °C), preventing viscosity drift and thermal overload.
• Integrated thermal overload protection safeguards the 200 W, 4-pole induction motor against sustained overcurrent or ambient overheating.
• Low-vibration, low-noise operation (< 55 dB(A) at 1 m) achieved through dynamic balancing of rotor assembly and elastomeric mounting isolation.
• NW25 (ISO-KF) suction port standardization ensures seamless compatibility with common vacuum tubing, traps, and manifold systems used in analytical and process instrumentation.
• Self-contained oil reservoir (800 mL capacity) with sight gauge and drain plug simplifies routine maintenance and oil replenishment without disassembly.

Sample Compatibility & Compliance

The VOP 60 is compatible with a broad range of vacuum-dependent equipment, including but not limited to: benchtop vacuum ovens (e.g., for solvent removal or moisture analysis per ASTM E1219), freeze-dryers (lyophilizers complying with USP and ISO 22033), residual gas analyzers (RGAs), electron microscopy sample preparation stations, thin-film deposition chambers (e-beam, sputtering), and semiconductor wafer handling modules. Its oil-lubricated configuration meets general-purpose vacuum requirements outlined in ISO 21360-1 (vacuum pump performance testing) and supports GLP-compliant workflows when paired with documented maintenance logs and traceable calibration records. While not intrinsically rated for explosive atmospheres, it may be deployed in Class 1, Division 2 environments when installed per NEC Article 500 guidelines and equipped with external explosion-proof motor controls where required.

Software & Data Management

The VOP 60 operates as a standalone mechanical device without embedded digital interfaces or firmware. It is fully compatible with third-party vacuum monitoring systems via analog pressure transducer inputs (0–10 V or 4–20 mA) connected downstream. When integrated into automated platforms—such as those governed by FDA 21 CFR Part 11—its operational status (on/off, thermal alarm, oil level warning) can be logged through programmable logic controllers (PLCs) or SCADA systems using discrete I/O signals. Routine maintenance intervals (oil change every 500 hours, filter replacement every 1,000 hours) are tracked manually or via electronic lab notebooks (ELNs) aligned with ISO/IEC 17025 documentation practices.

Applications

• Primary vacuum source for analytical instruments requiring rough-to-medium vacuum, including mass spectrometers (pre-vacuum stage), thermal desorption units, and gas chromatography sample introduction systems.
• Process vacuum supply for vacuum-assisted drying, degassing of resins and adhesives, and vacuum impregnation of porous materials.
• Support pump for diffusion or turbomolecular high-vacuum systems in R&D cleanrooms and pilot-scale coating facilities.
• Vacuum conditioning of hygroscopic reference standards prior to gravimetric analysis (per ISO 11843-4).
• Evacuation of glove boxes and inert-atmosphere chambers during purge-and-refill cycles.

FAQ

What type of vacuum oil is recommended for the VOP 60?
COSMA-100 synthetic hydrocarbon-based vacuum oil is specified for optimal viscosity index, oxidation resistance, and vapor pressure characteristics. Substitution with non-approved oils may compromise ultimate vacuum performance and accelerate wear.
Can the VOP 60 be operated continuously for 24/7 applications?
Yes—provided ambient temperature remains within 7–40 °C, oil level is maintained, and periodic maintenance (oil changes, filter inspection) follows the manufacturer’s schedule. Continuous duty is validated under ISO 21360-1 test protocols.
Is the VOP 60 suitable for pumping corrosive gases?
No. The standard configuration is not chemically resistant. For aggressive vapors (e.g., HCl, Cl₂, HF), a corrosion-resistant variant with stainless steel wetted parts and fluorocarbon seals must be specified separately.
Does the pump include an exhaust filter or oil mist separator?
The base model does not include an integrated oil mist separator; however, the NW25 exhaust port accepts standard ISO-KF-mounted coalescing filters (e.g., Vacuumer F-25 series) to meet local occupational exposure limits (e.g., OSHA PEL for mineral oil mist: 5 mg/m³).
How is motor phase compatibility handled for international use?
The VOP 60 is supplied with a fixed single-phase 220 V motor. Voltage conversion or frequency adaptation requires an externally rated variable-frequency drive (VFD) compliant with IEC 61800-3 electromagnetic compatibility standards.
