Description - Samoa DF100 Serie Manual De Operación Y Mantenimiento

Air operated double diaphragm pumps are air-powered, reciprocating positive displacement pumps with two pumping chambers. Two diaphragms,
centrally located in the chambers, separate the compressed air (dry side) from the fluid being pumped (wet side). A shaft transmits the reciprocating
motion of one diaphragm to the other. A directional valve alternatively distributes the air from one chamber to the other; thus a reciprocating
movement of the diaphragms is created. With each stroke, fluid is discharged by one of the diaphragms whilst the opposite diaphragm sucks new
fluid into the expanding chamber. Check valves, two on the discharge side and two on the suction side, control and direct the fluid flow.
