Bearings in centrifugal pumps - SKF

single stage centrifugal pump are illustrated in the figure 1.7. The axial load is equal to the sum of the forces: 1. the hydrostatic force acting on the impeller’s front shroud and hub (back) shroud due to the hydraulic pressures acting on the surface areas of the shrouds 2. the momentum force due to the change

Multi-Stage Centrifugal Compressors - elliott-turbo.com

single-stage testing is performed in various configurations, such as with vaneless or vaned diffusers, or using high or low tip Mach numbers. Higher and lower flow stage ratings are derived from the prototype test data to form a “family” of stages. Within each stage family, impeller geometry is fixed;

ENGINEERING GUIDE YORK YZ Centrifugal Chiller

The compressor is a single-stage centrifugal design directly driven by a hermetically-sealed motor with a VSD. A cast-aluminum, fully-shrouded impeller is mounted directly to the motor shaft. Impeller seals employ a labyrinth geometry, sized to provide minimal thrust loading on the impeller throughout the operating range. The impeller is ...
