Pumps

MSI performs design and analysis of centrifugal and axial pumps of all sizes and horsepower.  Markets served include energy, oil & gas, water & wastewater, chemical, pulp & paper, aerospace & defense, and automotive, among others.  MSI performs 3-D finite element analysis of stress, deflection, and vibration.  CFD is used to perform hydrodynamic evaluation from meanline performance analysis to complex analyses of primary and secondary flow fields through all stationary and rotating components.  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.  Explore our case studies or contact an engineer to discuss your needs.

Seismic Analysis of a Vertical Turbine Pump

A nuclear power company purchased several new service water vertical turbine pumps for their power plant.  As for all new nuclear installations, it needed to be shown that these pumps could withstand a standardized earthquake loading without structural failure.

Resolving Vertical Pump Lineshaft Failures

MSI was contracted by a major petrochemical company to determine the reasons for chronic lineshaft failures in some 100 foot (30 meter) long vertical pumps, in service on an offshore oil platform.   The natural frequencies predicted by the model, and their associated mode shapes, were to be evaluated for possible participation in the failures.

Pipe Strain Causing Pump Vibration

Mechanical Solutions, Inc. (MSI) was contracted by a coal power electricity generation plant to perform thorough and specialized vibration testing of the main turbine driven boiler feed pump (TDBFP). It was previously reported that for several years, high shaft vibration had been detected at the pump inboard bearing (IBB), but mostly in the X direction. The vibration appeared to be proportional to the load of the plant and sensitive to the alignment.
