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: smallest rate of flow that the pump can be expected to deliver continuously without risk of internal damage when operated at the rated speed and on the liquid for which it was supplied; Name: Min. feed flow
