To correct for the pumped liquid's viscosity, Figures 6-7 and 6-8 are used to approximate the equivalent water performance. The figures, developed by the Hydrauiic Institute, are used by entering the bottom with the viscous flow rate (gpm), moving vertically upward to the desired viscous head (head per stage for multistage pumps), then moving horizontally to the left or right to the viscosity line, and proceeding vertically upward to the correction-factor curves for the head and capacity. The equivalent water-performance values are then obtained by dividing the viscousperformance values by the correction values.
If low rates carmot be avoided, a by-pass may be required to prevent vaporization and subsequent pump damage. Thus, vaporization of the pumped liquid can occur two ways: (1) the NPSH required is not being met and cavitation occurs in the liquid causing vapor bubbles that can severely damage the impeller or (2) the pump horsepower overheats the pumped liquid, forming vapor bubbles that can (and normally will) damage the pump. Excess heat resulting in pumping a fluid can be avoided by determining t}re minimum flow required to allow proper heat dissipation.
