These lightweight, oil-free filtration pumps are designed for flask filtration, vacuum manifold, vacuum blotting, vacuum dessication, and solvent degassing applications The filtration pumps are available with a vacuum gauge and regulator for added control. The high quality, smoothly-dampened brass vacuum gauge exhibits minimal needle bounce, and a convenient regulator valve provides fine vacuum adjustment. Pumps feature premium, corrosion-resistant fluoropolymer resin diaphragms, Ryton heads, and Kalrez resin valves (except for pumps 14224-116 and 26678-052 which feature Viton valves) for handling aggressive corrosives without risk of damaging the pump. There are no metal or coated metal wetted parts within the pump heads.
