Pumping Viscous Fluids Using Centrifugal Pumps (0.6 CEUs)

 

Introduction

Pumping viscous fluids presents unique challenges compared to handling low-viscosity fluids like water. Standard pump characteristic curves, pump performance acceptance testing protocols, and related information are generally based on water viscosity. However, pump performance tests conducted with water are only valid for fluids with viscosities up to 20–30 cSt. Beyond this range, viscosity significantly impacts pump performance, requiring adjustments in selection, design, and testing procedures. This course provides a comprehensive understanding of pumping viscous fluids using centrifugal pumps, addressing key challenges and solutions.
