Centrifugal & Axial Pumps
MSI performs design and comprehensive analysis of centrifugal and axial pumps of all sizes and horsepower. Markets served include process, petrochemical, water & wastewater, chemical, pulp & paper, aerospace & defense, and automotive, among others. MSI performs 3-D finite element analysis of stress, deflection, and vibration. The best modern CFD codes are used to perform hydrodynamic evaluation from meanline
performance analysis to complex CFD of primary and secondary flow fields through all stationary and rotating components. MSI's fluid dynamics team is led by Dr. Edward Bennett. Detailed experimental evaluations can also be performed in the field or in MSI's laboratory test rigs. Testing capabilities include performance and efficiency quantification, nozzle load stresses, rotor pressure oscillation as reported by multi-channel telemetry, vibration modal testing and vibration operating deflection shapes (ODS) testing.
