1/4" PNEUMATIC DOUBLE DIAPHRAGM PUMP, DC20, DIRECTFLO SERIES, CONDUCTIVE ACETAL-PTFE-PTFE
Air operated double diaphragm pumps for dosing and transferring a wide variety of fluids. Good for solvents (most ketones, acetates, aldehydes, aromatic and chlorinated hydrocarbons), solvent and water based flexo and gravure inks, varnishes and paint.
For OEM applications and industrial processes with lower flow rates. Unbalanced spool valve air motor requires lower start-up pressure for finer flow adjustment using regulating air pressure.
Pump wetted materials are compatible 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).
