Some Observations Relating to Suction Performance of Inducers and Pumps
Tests performed with a remarkable number of inducers and pumps indicate that there exists a definite pattern of the manner in which the velocity of flow of the liquid and the peripheral velocity of the inlet tips affect the suction characteristics of a pump. Within certain limits, this pattern is unaffected by the shape of the blades, by the type of the pump, and by the flow rate. This consistency of behavior allows one to calculate the NPSH-requirements of a pump along its total working range, provided that the suction conditions are not disturbed by a particularly unfavorable blade geometry or by other effects.
