Pump suction specific speed: Is it a treacherous friend
As pump design has gone from an art to a science, the complexities of fluid dynamics have come into clearer focus, driven by field-application problem solving and advancing technology. The past two decades have seen: (1) verifiable state-of-the-art advances in hydraulic design; (2) much-improved knowledge of causes of pump failure, including those from recirculation; (3) the beginning of further refinement of the new suction-specific-speed guidelines - and interaction with design concepts; (4) differentiation between good and bad designs through empirical data, making use of suction specific speed; (5) and as discussed in this article an understanding that suction specific speed (S) alone is inadequate for establishing the differentiation. Although the S is important in understanding pump performance, look at the broad picture when applying the theory.
