Description: index relating flow, total head and rotational speed for pumps of similar geometry; Name: specific speed
Description: Speed that characterizes a pump in terms of its speed, flow rate per impeller eye, i.e. total flow for single-flow impeller, half flow for double-flow impeller, at the best efficiency point and head per stage at maximum impeller diameter ; Name: Specific speed
Description: The operating temperature TS2 is the maximum value of the operating temperature defined from a safety point of view by the manufacturer of the system for the various components. The temperature point TS2 is in correlation to the pressures PS2+ and PS2-; Name: Min. permissible operating temperature at TS2, room2
