It's actually an air powered pump that makes use of the venturi effect. The high velocity air that passes through the smaller brass tube, mixes with the air that it's already in the larger copper tube. The air that is mixed and shot from the outlet must be replaced, and this is what causes the suction to happen. Support my videos!:
