Description: load in line with the pump shaft caused by hydraulic forces acting on the impeller shrouds and rotor; Name: axial load
Description: Residual axial thrust on the pump rotor on which the thrust-bearing selection is based; Name: Design axial load
Description: net positive suction head (NPSH) from flow rate at best efficiency point for actual impeller (indication of the minimum inlet pressure in meters required for the pump to deliver according to the QH curve. related to the optimum duty point at the current impeller diameter); Name: net positive suction head for Q opt at actual impeller size
