Description: lowest flow at which the pump can operate without exceeding the vibration limits imposed by this International Standard; Name: lowest ongoing stable flow
Description: Lowest flow at which the pump can be operated without it adversely affecting ist performance in terms of life expectancy, noise and vibrations ; Name: Minimum continuous stable flow
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
