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: permanent operation, short-term operation or periodic operation characterized by one of more loads and which remains unchanged during a certain period, or, in the case of non-periodic operation, where the load and speed generally change within the permissible operating range; Name: Operation type time sequence of the drive
