CONTROLLING FLUID FLOW THROUGH CENTRIFUGAL PUMP
A centrifugal pump having a self-regulating impeller discharge shutter which controls the size of flow passages from the pump impeller to the volute according to the flow demand on the pump. When the pump is operating at the design flow rate, the flow passages can be nearly fully open and, when ther...

| description | A centrifugal pump having a self-regulating impeller discharge shutter which controls the size of flow passages from the pump impeller to the volute according to the flow demand on the pump. When the pump is operating at the design flow rate, the flow passages can be nearly fully open and, when there is a lesser demand, the area of the flow passages can be correspondingly reduced to improve stability and minimize the temperature rise within the pump. The position of the impeller discharge shutter is automatically controlled by exposure to the static pressure at the tip of the impeller and the pressure in the volute which exert oppositely-acting forces on the impeller discharge shutter. |
