Suction Conditions and Limitations on Suction Performance
Every piece of machinery is preordained to have its Achilles’ heel. That of the centrifugal pump can generally be found in its suction. This fact must have been discovered quite early in the commercial application of centrifugal pumps and, probably, accepted as an inescapable penalty exacted in return for the advantages that were made available by this newer means of raising water to a desired location at a reasonable cost. And because most centrifugal pump troubles occur on the suction side of the pump, it is imperative to understand how to relate the suction capability of a centrifugal pump to the suction characteristics of the system in which it will operate.
