Information
Air operated double diaphragm pumps for dosing and transferring a wide variety of fluids.
For OEM applications and industrial processes with lower flow rates.
Unbalanced spool valve air motor requires lower start-up pressure for fine 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.
Fully groundable ATEX certified pumps are available for use in potentially explosive atmospheres (Ex II2 GD IIB/IIC 95 ˚C).
