Air-Operated Diaphragm Pumps

SAMOA pneumatic pumps are air-operated, positive displacement double diaphragm pumps with a reciprocating motion. 
These pumps are designed for dosing, spraying, transferring, evacuating and distributing a wide variety of fluids.
They have two opposite pump volumes and a diaphragm divides each volume into an air and a liquid chamber. The diaphragms are connected with a shaft. During one pumping stroke, the fluid is suctioned into one fluid chamber, while simultaneously it is discharged from the opposite fluid chamber.
