Overview
The BIOVAC BV-10 is a direct-drive, oil-lubricated rotary vane vacuum pump engineered for reliable primary and rough vacuum generation in laboratory and light industrial environments. Based on the classical Couette flow principle, it achieves continuous gas removal through synchronized rotation of precision-machined vanes within an eccentrically mounted rotor chamber. The pump operates without internal springs—eliminating a major source of mechanical fatigue and vibration—thereby delivering stable suction performance across extended duty cycles. Designed to meet ISO 21360-1 (vacuum pump performance testing) and ISO 8573-1 (compressed air purity) reference methodologies, the BV-10 serves as a foundational vacuum source for applications requiring base pressures down to 0.5 Pa under closed-system conditions and sustained pumping speeds of 9.9 m³/h at 50 Hz.
Key Features
- Springless vane design ensures low mechanical noise (<62 dB(A)) and minimal vibration amplitude (<2.5 µm RMS), enhancing long-term bearing integrity and reducing micro-vibrational interference in adjacent instrumentation.
- Integrated oil anti-backstream valve prevents hydrocarbon back-diffusion into vacuum chambers during shutdown or pressure recovery—critical for maintaining cleanliness in gloveboxes, evaporators, and mass spectrometer inlet systems.
- Modular cooling architecture supports ambient air cooling as standard, with field-upgradable oil-cooling or water-jacketed heat exchanger options to sustain thermal equilibrium during continuous operation above 70% duty cycle.
- Quick-access service layout enables full oil change, vane replacement, and filter maintenance in under 15 minutes without specialized tools—aligning with GLP-compliant preventive maintenance schedules.
- CE-marked and ISO 9001:2015 certified manufacturing process guarantees traceable component sourcing, batch-specific oil viscosity validation (BSO 46, kinematic viscosity 46 cSt @ 40°C), and 100% factory leak-testing per ISO 2859-1 sampling standards.
Sample Compatibility & Compliance
The BV-10 is compatible with standard KF25 vacuum fittings and integrates seamlessly with common lab-scale vacuum receivers, rotary evaporators, freeze dryers, and vacuum desiccators. It meets the operational requirements of ASTM D2873 (vacuum drying of polymers), ISO 10993-12 (biocompatibility extraction under reduced pressure), and USP (sterile processing vacuum validation). While not intrinsically safe, its non-sparking motor enclosure (IP54 rating) permits use in general-purpose chemical laboratories compliant with NFPA 45 ventilation guidelines. All lubricants conform to ISO 6743-15 category DVA specifications for vacuum pump oils.
Software & Data Management
As a standalone mechanical pump, the BV-10 does not include embedded digital controls or data logging hardware. However, its analog output signals (0–10 V vacuum level feedback via optional Pirani sensor interface) are compatible with third-party SCADA platforms (e.g., LabVIEW, Ignition, Siemens Desigo CC) for centralized vacuum system monitoring. Maintenance logs—including oil change timestamps, cumulative runtime hours, and pressure decay test records—can be documented in accordance with FDA 21 CFR Part 11 when paired with validated electronic lab notebooks (ELNs) supporting audit-trail functionality.
Applications
- Rough vacuum generation for rotary evaporation of solvents (e.g., acetone, ethanol, ethyl acetate) at ≤50°C bath temperature.
- Primary vacuum stage in multi-stage systems feeding diffusion or turbomolecular pumps for high-vacuum deposition processes.
- De-airing of resin composites and dental impression materials prior to curing.
- Pressure-controlled drying of hygroscopic reference standards (e.g., NIST SRM 1970) in analytical balance enclosures.
- Vacuum impregnation of porous ceramics and metal foams in materials science prototyping workflows.
FAQ
What is the recommended oil change interval for continuous operation?
Under typical 8-hour/day laboratory use, oil should be replaced every 500 operating hours or semiannually—whichever occurs first. Extended intervals require in-service oil analysis (ASTM D6595) to verify oxidation stability and particulate load.
Can the BV-10 be used with corrosive vapors such as HCl or Cl₂?
No. The pump is not chemically resistant to halogenated or acidic gases. For such applications, a corrosion-resistant diaphragm pump (e.g., KNF N814.1.2) or fluoropolymer-lined scroll pump is required.
Is the motor compatible with 220 V single-phase power supply?
The BV-10 is configured for 380 V three-phase input by default. A 220 V single-phase variant is available upon request but requires derating of maximum duty cycle to 60% to prevent thermal overload.
Does the pump include an exhaust filtration system?
Standard configuration includes a basic oil mist separator; an optional activated carbon + HEPA exhaust filter kit (BIOVAC EF-10) is available for solvent-laden exhaust streams requiring VOC abatement per ISO 14644-1 Class 5 cleanroom exhaust protocols.
