SAMOA is committed to design and manufacturing excellence, environmental sustainability and a healthy and safe workplace; our work processes and facilities are consequently ISO 9001, ISO 14001 and OHSAS 18001 certified.
AODD pumps with central flow technolgoy | Directflo®
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).
Directflo® pumps are based in an " inside-out" technology: the fluid is pumped through the centre of the pump and the compressed air acts on outside face of the diaphragms.
Plastic Directflo®
Plastic Directflo® diaphragm pump wetted bodies are compatible with even the most aggressive chemicals, and the plastic directional air valve and air chamber covers are suitable for use in corrosive environments.
Metal Directflo®
Metal Directflo® diaphragm pumps are extremely robust and thanks to a wide range of wetted materials are compatible with many fluids.

DC20 Plastic Pump Performance Curve
DC20 PLASTIC PUMPS
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).
