Enhancement of Pump/Plant Performance by Correct Evaluation of Process Fluid Viscosity Variations and Pump Geometry
MetadataShow full item record
Case Study 16: In the modern pump industry, processed fluids are characterized by a wide spectrum of viscosity values. An unpredicted variation of actual process fluid properties, including viscosity, may lead to unexpected pump performance alteration. Also manufacturing deviations from expected internal pump geometry may cause pump performance deterioration. Both causes may determine undesired limitations of the pump operating range and plant production loss. The present Case Study illustrates a real case story of incorrect evaluation of the process fluid viscosity and pump geometry deviations, both determining performance deteriorations, described through a detailed evaluation of the internal pump losses. From the presentation of a real case, this case study highlights the importance of both the correct evaluation of viscous effects and the internal pump geometry through the application of existing loss correlations.
