Abstract
The present invention is directed to a pump casing and a centrifugal pump comprising a single piece casing, the casing comprising a first cut-water fluid flow path, a second cut-water fluid flow path, a first joint-water path, a second joint-water path, and an impeller cavity, the first cut-water fluid flow path and the second cut-water fluid flow path communicating with the first joint-water path and the second joint-water path, the pump further comprising an impeller positioned within the cavity, and a suction head overlaying the impeller. The first joint-water path communicates with a first discharge nozzle and the second joint-water path communicates with a second discharge nozzle, the first discharge nozzle and the second discharge nozzle situated substantially at opposing ends of the casing.
