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.
