Filtration Diaphragm Pump for Lab Applications

KNF's LABOPORT Filtration Series diaphragm pumps are designed for a variety of lab applications, including flask filtration, vacuum blotting, vacuum manifold, and vacuum desiccation. These lightweight, easy-to-use, and quiet pumps notably promote “green” operations by performing cleanly without pump oil, conserving water by eliminating water aspirators, supplying consistent vacuum levels, and eliminating any potential for solvent-contaminated waste generated by oil-type pumps and water aspirators. The pumps also benefit from patented multi-port valves, which increase performance and can tolerate occasional liquid condensate drawn into the system without incurring damage. Pump heads integrate corrosion-resistant wetted parts for added protection and longer service life. The heavy-duty, all-ball-bearing motor is lubricated for life. This series of pumps is available in various models offering alternatives to oil-lubricated pumps, water aspirators, piston pumps, and house vacuum. The pumps can achieve flowrates from 5.5 L/min to 37 L/min and vacuum from 15 Torr (29.3 in. Hg) to 120 Torr (25.2 in. Hg), depending on the version.
