Ref.: DF30PDSTSTTBAS
1/2" PNEUMATIC DOUBLE DIAPHRAGM PUMP, DF30, DIRECTFLO SERIES, CONDUCTIVE ACETAL-PTFE-PTFE
Air operated double diaphragm pumps for dosing, spraying, transferring and distributing a wide variety of fluids in small flow rates applications. Good for solvents (most ketones, acetates, aldehydes, aromatic and chlorinated hydrocarbons), solvent and water based flexo and gravure inks, varnishes and paint.
Pump wetted parts are compatible even with the most aggressive fluids and are suitable for use in corrosive environments. Air motor (directional air valve and air chamber covers) is made of polypropylene.
This model is a fully groundable ATEX certified pump, for use in potentially explosive atmospheres (Ex II2 GD IIB/IIC 95 ˚C).
