A proper clearance in between the ending point of plunger stroke and the valve should be provided such that the triplex plunger pump could function properly. Suctioning water will be inadequate, if the clearance is too large. On the contrary, the reciprocating plunger will be easier to collapse, wear or broken, if the clearance is too small. Therefore, a proper clearance is particularly important. However, the clearance is the cumulative tolerances of its modules and components. The purpose of this paper is to use statistical models of tolerance allocation and quality loss function to optimize the tolerance of all the modules and components. The significant tolerance modules are found and revised. The results show that the improvement from lossing NT $ 174,584,160 to gaining NT $ 401,427,532 dollars.
