International Classification:

F04D 29/70
F04D 13/04
F04F 1/18

Abstract:

The present disclosure relates to a fluid pump which has a pump casing, a top cap securable to an upper end of the pump casing and having an air intake port and a fluid discharge port. A fluid discharge tube extends to adjacent a lower end of the pump casing. A one-way check valve is disposed adjacent the lower end of the pump and forms a one-way path to admit fluid into the pump casing during a fill cycle of operation of the pump. A one-way check valve at the discharge port allows fluid to escape during a discharge cycle. An auger element is disposed inside the pump casing for causing a swirling, rotational fluid flow during a fluid eject cycle, in response to a jet of compressed air released into the pump casing, in which fluid having collected within the pump casing is forced by the jet of compressed air into and up through the discharge tube, and out from the pump casing.

Abstract:

A submersible fluid pump suitable for use in a landfill well includes an outer case extending along a vertical axis and at least partially defining an interior of the fluid pump, a fluid inlet and outlet, a discharge tube within the outer case and disposed between the fluid inlet and the fluid outlet, a float positioned around the discharge tube and within the outer case such that the float is within the discharge tube and the outer case, the float being movable along the discharge tube in an axial direction, a pneumatic valve configured to introduce pressurized air into the interior of the fluid pump, an actuator configured to open and close the pneumatic valve, and a plurality of magnets comprising a first magnet fixed with respect to the actuator and a second magnet fixed with respect to the float, the second magnet configured to magnetically repel the first magnet as the float moves to tip the actuator to either open or close the pneumatic valve.
