ABSTRACT:
A double action fluid pump consisting of the combination of a rotor with multiple blades feathered at an angle perpendicular to the fluid surface, all enclosed within a casing which is contoured to the said rotor-blade assembly and its its related fluid movement area, said casing having a main suction chamber and a discharge chamber in line with each other and in line with the lower one third periphery of the rotor which requires the fluid to flow in a straight line through the pump. A supplementary suction chamber is located in the upper quadrant of the casing on its discharge side which furnishes additional fluid to the main suction chamber to balance the vacuum-pressure relationship of the two suction chambers and cause a rise of pressure behind the blade travel path, thereby minimizing or eliminating blade cavitation as well as increasing the supply and momentum of fluid through the main suction chamber.
