Abstract

The leakage losses in gear pumps, represent a special interest in engineering service. Herein, the prediction of leakage flow, as related to the pump geometry and fluid properties, has been assumed. Theoretical analysis has been developed to estimate the leakage flow through the side and radial clearances, during meshing process, and by squeezing of the trapped fluid. Theoretical and experimental analysis showed a satisfactory agreement between the estimated and the measured values.
