ABSTRACT:
An irrigation booster pump assembly that includes a frame assembly, a power supply supported by the frame assembly, a vertical drive shaft rotatably supported by the frame assembly, and a propeller. The vertical drive shaft has an upper end drivingly connected to an output shaft of the power supply. A propeller is mounted on a lower end of the vertical drive shaft. The propeller has blades or vanes pitched for pushing water in a downward direction away from the power supply during normal operation of the power supply. The pump assembly further includes a cylindrical member disposed concentrically about the propeller, the cylindrical member rotatably supporting a lower end portion of the vertical drive shaft. The cylindrical member is connected to the frame assembly by a plurality of circumferentially spaced elongated rods, each rod having one end fixed to the frame assembly and another end fixed to the cylindrical member. A lift lug assembly is connected to the frame assembly and extends over the power supply for lifting the pump assembly. A cover assembly is mounted to the lift lug assembly for covering and protecting the pump assembly.
