Leybold Sogevac SV40 BI Single-Stage Oil-Sealed Rotary Vane Vacuum Pump (22.7-27.7 cfm)
Product Description
The Leybold Sogevac SV40 BI is a single-stage, oil-sealed rotary vane vacuum pump designed for laboratory and industrial applications including molecular diagnostics and bioprocessing. The pump features:
- Rotor mechanism with three sliding vanes within an eccentric stator, forming three variable volume chambers for efficient gas compression and evacuation.
- Oil injection in the inlet chamber ensures airtight sealing, continuous lubrication, and effective cooling, critical for maintaining stable vacuum conditions essential in biotechnology workflows such as gene editing and synthetic biology.
- Oil separation system with gravity and exhaust filter for reliable oil recovery and minimal contamination risk. A float valve prevents atmospheric air ingress when oil levels are low, maintaining vacuum integrity.
- Anti-suckback valve on the KF-25 inlet flange restricts oil backflow upon pump stop, suitable for working pressures below 100 mbar, though not a safety valve; for critical applications, an additional safety valve is recommended to prevent oil contamination.
- Performance specs include an inlet KF-25 connection, outlet with 1.25" NPT internal thread, flow rate range of 22.7–27.7 cfm, and an ultimate vacuum pressure below 1.1 Torr.
Widely used in clinical diagnostics, biomanufacturing, and synthetic biology research, this pump supports workflows requiring stable medium vacuum levels, such as vacuum filtration and rotary evaporators in live-cell imaging and molecular cloning. Its robust oil-sealed rotary vane design ensures consistent vacuum performance crucial for precision lab applications.
