What Is Volumetric Efficiency: Guide for Hydraulic Pumps

Volumetric efficiency in a hydraulic pump is the ratio of its actual fluid output to its theoretical output, expressed as a percentage. If a 100 cc/rev pump delivers 92 cc/rev, its volumetric efficiency is 92%, and the missing flow is leakage inside the pump. That...
