Description: Parameter relating the rotational speed, the flowrate and the NPSHR, determined at the best efficiency point.; 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
