My January 2013 Pumps & Systems’ column focused on the reduction in motor horsepower (HP) as frequency is reduced by a variable frequency drive (VFD).

How important is the hardfacing requirement below the sleeve bearings in the 416 stainless steel (ss) shaft of a vertical turbine pump used to move condensate? Consider an example with a condensate pump that has carbon bearings.

Brazilian engineer Ricardo Martuscelli emailed me to suggest that I create graphs that illustrate the effects of speed (rpm) and the density of the pumpage on the NPSH requirements of these machines.
