Effects of Viscosity on Positive Displacement Pumps

Doug Robinson01 Aug, 2021Business

Positive displacement pumps move fixed volumes of fluid mechanically through a system. Therefore, one might conclude that fluid viscosity has little effect on the output of the pump. This, however, is a misconception and can lead to severe issues in a hydraulic system unless the effects of viscosity are well understood, and the system designer properly communicates the information to the pump engineers.
