KNF Neuberger* Filtration Pumps

This inexpensive line of diaphragm vacuum pumps are designed by KNF to provide effective vacuum for a variety of filtration jobs including bottle top and manifold filtration, vacuum degassing and solid phase extraction. Maintenance-free, there is no pump oil to change, nor is water or drain required for operation. Compact and portable, KNF uses only corrosion-resistant materials to avoid damage from corrosive solvents. KNFs multi-port valves are highly resistant to damage from liquid condensate, and pass thru with no loss of performance.
These convenient KNF filtration pumps are lightweight and easy to use for your flask filtration, vacuum manifold, blotting and desiccation applications. There are no metal wetted parts within the pump heads. The high quality, smoothly-dampened brass vacuum gauge exhibits minimal needle bounce, and a convenient regulator valve provides fine vacuum adjustment. KNF filtration pumps are available with either a vacuum or pressure gauge and regulator assembly, or as a stand-alone pump.
