Abstract
Single suction centrifugal pumps, pump casings, pump systems and vehicles for using pumps which include a single piece casing having a first cut-water fluid flow path, a first discharge nozzle, and a second discharge nozzle, the first cut-water fluid flow path communicating with the first discharge nozzle and the second discharge nozzle and the nozzles being situated at opposing ends of the pump such that center outputs of the nozzles are offset from a horizontal centerline of the casing and the first nozzle is positioned a greater distance from a lower casing wall of the pump as compared to the second nozzle so that the casing may be connected to output piping for both sides of the vehicle and at a low profile within the vehicle.
Claims14
A single piece pump casing comprising:
- a first cut-water fluid flow path, a second cut-water fluid flow path, a first joint-water path and a second joint-water path, 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 first joint-water path communicating with a first discharge nozzle and the second joint-water path communicating with a second discharge nozzle, the first discharge nozzle and the second discharge nozzle situated substantially at opposing ends of the casing, the first discharge nozzle defining a first center output point and the second discharge nozzle defining a second center output point, the first center output point and the second center output point defining a horizontal line offset from a center point of a center opening passing through the casing.
A centrifugal pump comprising:
- an impeller contained within a casing, the casing comprising a first cut-water fluid flow path, a first discharge nozzle, and a second discharge nozzle, the first cut-water fluid flow path communicates with the first discharge nozzle and the second discharge nozzle, the first discharge nozzle and the second discharge nozzle situated substantially at opposing ends of the pump and a first center output point of the first discharge nozzle and a second center output point of the second discharge nozzle defining a horizontal line offset from a horizontal centerline of the casing.
A centrifugal pump casing, comprising:
- a first cut-water fluid flow path defined at least in part by a first cut-water wall, a second cut-water fluid flow path defined at least in part by a second cut-water wall, a first joint-water path and a second joint-water path, 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 first joint-water path communicating with a first discharge nozzle and the second joint-water path communicating with a second discharge nozzle, the first discharge nozzle and the second discharge nozzle situated substantially at opposing ends of the casing, the first discharge nozzle defining a first center output point and the second discharge nozzle defining a second center output point, the first center output point and the second center output point defining a line offset from a center point of a center opening passing through the casing and in a spaced relationship with respect the second cut-water wall.
