ABSTRACT:
A self-priming, vertical-shaft centrifugal pump having an impeller design which creates an upward thrust and which is heavy enough to carry an engine having a standard weight flywheel through a compression stroke. The pump is comprised of a vertical-shaft engine mounted onto a pump housing. The pump housing includes an inlet chamber, a pumping chamber, and a separation chamber. The shaft of the engine protrudes into the pumping chamber and is mounted to an impeller which rotates within the pumping chamber. The pump draws liquid into the pumping chamber from an inlet communicating liquid entrained with gas to the pump. The impeller uses centrifugal force to pump the liquid and gas mixture out of the pumping chamber and into the separation chamber. In the separation chamber, the entrained gas is removed from the liquid and exhausted into the atmosphere, and the liquid is communicated back into the pumping chamber to mix with additional liquid entrained with gas until all of the entrained gas from the incoming mixture is removed. To reduce the axial load on the bearings of the engine, a pressure space is provided below the impeller shroud which is in communication with the high pressure fluid expelled by the impeller. The high pressure space pushes the impeller upward to thereby lessen the load on the engine bearings. The shroud of the impeller is sufficiently heavy to carry the engine through a compression stroke so that an engine having a standard weight, less expensive flywheel can be used.
