Designed for Demanding Vacuum Applications
The Welch WOB-L Piston Pump Model 2561B-50 is built for continuous-duty performance in laboratory and industrial environments. It delivers a deep vacuum (down to 60 Torr) with a free air displacement of 1.2 CFM, making it suitable for filtration, aspiration, degassing, and vacuum drying. Its oil-free operation eliminates contamination risks and reduces maintenance, while the rugged aluminum housing and permanently lubricated bearings extend service life.
This pump is thermally protected and operates quietly, with vibration isolation mounts to reduce noise and wear. It’s a compact, benchtop unit that plugs into standard 115V outlets, making it easy to integrate into existing setups.
