SAMOA Pump's revolutionary design is turning the Air Diaphragm Pump World Inside Out!

DirectFlo® Technologies PDF

Seeing is believing. Watch the 1-2 minute videos and see for yourself.

Diaphragm Replacement Video

Save 30-50% on your compressed air utilities and rebuild your pumps on line.

CAT DirectFlo® UP USA PDF

The SAMOA DirectFlo® pump is designed inside-out with fluid flowing through the pump center, and air outside of the diaphragms. Our revolutionary design employs our patented frictionless air valve coupled with uniform pressure gradient air driving "overmolded" diaphragms. Together they make SAMOA DirectFlo® pumps the most reliable and efficient AODD pump in the world.

SAMOA DirectFlo® pumps are by far the easiest to repair. Diaphragms, balls, seats or air valve replacement without complete disassembly or even removing the pump. No other AOD pump can do this.
