Joe Evans, Ph.D When we start the pump selection process for a particular application, one of our major concerns is efficiency. If several different models, of similar quality, meet our conditions we will usually select the one with the highest efficiency. After all, higher efficiency reduces the cost of electrical power. There are times, however, when efficiency can take a back seat to the true, overall cost of operation. Solids handling pumps used in municipal and...

Understanding Pump Cavitation

Hydraulic Institute. (Figure 1)NPSHA is the net positive suction head available of the system to the pump, and it is calculated during design and construction or determined from the actual system. And a valid equation to determine the NPSHA is:Where:Pb = atmospheric pressure (barometric pressure)Pv = vapor pressure of the delivery fluidPi = pressure in the closed intake vesselPs = pressure at the suction branch? = density of the delivery fluidci = velocity of the fluid in the intake vesselcs =...
