  • Protecting centrifugal pumps from cavitation through applied mathematical technique
    Patent number: 11965513
    Abstract: A system and method for operating centrifugal pumps related to net positive suction head (NPSH), including identifying a group of centrifugal pumps and deriving an equation for the group based on manufacturer data of the centrifugal pumps collectively in the group, the equation correlating NPSH required (NPSHr) with flowrate of pumped fluid, wherein the manufacturer data includes NPSHr for each centrifugal pump of the group as a function of the flowrate of the pumped fluid. The technique includes specifying a NPSH margin for NPSH available (NPSHa) above the NPSHr.
    Type: Grant
