Best Practices In Selecting And Applying Positive Displacement Pumps
Selecting a positive displacement pump is many times a confusing process. Unlike centrifugal pumps were pumping technology is familiar, positive displacement pumps operate differently than centrifugal and there is a wide diversity in product capability. Pump design, system parameters, and characteristics of the liquid pumped are all key factors in determining which pump is most suited for a given application. This paper covers design elements of nine different positive displacement pumps, their respective operating limits, performance characteristics, and a number of factors to consider when choosing a pump. Typical application areas are also discussed.
