Description: Suction specific speed nss as defined in EN 12723 is used to classify the suction characteristics of centrifugal pumps. It is derived from the similarity conditions for cavitation and calculated on the same formal basis as the specific speed ns.; Name: suction specific speed
Description: Speed that characterizes a pumps cavitation performance in terms of its speed, optimum rate of flow per impeller eye at best efficiency point and NPSH3 at best efficiency point for the first stage at maximum impeller diameter ; Name: Suction-specific speed
Description: Measured energy consumption of the unit; Name: Energy consumption
