Leybold Sogevac Rotary Vane Vacuum Pump SV 40-65 BIFC

Leybold SOGEVAC SV 65 B IFC Rotary Vane Vacuum Pump – 42 CFM, Single-Phase

The Leybold SOGEVAC SV 65 B IFC is a premium, single-stage, oil-sealed rotary vane vacuum pump engineered for demanding industrial and laboratory applications. The "IFC" designation stands for Integrated Frequency Converter, a built-in variable speed drive that allows this pump to operate on a standard single-phase power supply (200-240V) while delivering the robust performance typically requiring a three-phase setup. Yielding an impressive 42 CFM (71 m³/h) pumping speed and an ultimate partial pressure of ≤ 0.2 mbar, it provides fast, reliable pump-downs. Known for its exceptionally compact footprint and ultra-quiet operation, the SV 65 B IFC integrates all major lubrication circuits directly into the pump housing, eliminating external piping and significantly reducing the risk of oil leaks.

Technical Performance and Design

• Integrated Frequency Converter (IFC): Allows the pump to run at optimal speeds regardless of local grid frequency variations, providing consistent, high-capacity pumping performance and excellent energy efficiency from a standard 1-phase source.

• Ultra-Quiet Operation: Advanced mechanical tolerances and optimized internal lubrication circuits ensure a constant, low noise level (≤ 60 dB(A)) across all working pressures, dramatically improving the acoustic comfort of the workspace.

• Front-Facing Maintenance: Designed with the technician in mind, all routine maintenance points—including the unambiguous angle-mounted oil sight glass, oil fill/drain ports, and the exhaust demister—are easily accessible from the front panel.

• Integrated Exhaust Filter: Features a built-in exhaust demister system with an optimized oil return line, ensuring extremely clean exhaust air and minimizing oil consumption even during continuous, high-throughput operation.

Key Benefits & Applications

• Vacuum Packaging & Processing: The robust water vapor tolerance and integrated gas ballast make it highly capable of handling the outgassing and moisture associated with food packaging, freeze-drying, and potting systems.

• Simplified Retrofitting: The compact footprint and 1-phase power requirement allow this pump to easily replace older, bulkier pumps without needing costly 3-phase electrical facility upgrades.

• Clean and Green: The highly integrated housing minimizes the number of external seals, drastically reducing the chance of messy oil leaks and keeping the laboratory or production floor clean.

• High Uptime: Simplified access to the exhaust demister and clearly visible dual oil sight glasses mean routine preventative maintenance takes minutes, preventing costly system downtime.
