Centrifugal pumps and compressors are both rotating equipment devices. Each is a machine that imparts kinetic energy to the fluid to create
Impellers – why underfile?
Underfiling is the removal of material from the underside (also back side, “non-working” side, or suction side) of an impeller vane at the inlet or
Diffuser versus volute
The stator section of a centrifugal pump, after flow exits the impeller, is usually either a ‘diffuser’ or a ‘volute’. The purpose of each of these
Multi-stage pump in-line (tandem) versus opposed impeller arrangements
Common to early twentieth century multi-stage rotodynamic (centrifugal) pumps were design features for minimizing axial thrust. At that time the
