Description: smallest flow rate at which the pump can operate without exceeding the noise and vibration limits specified in the order; Name: Min perm stable flow rate
Description: Lowest flow at which the pump can operate without exceeding the noise and vibration limits imposed in the order ; Name: Minimum allowable 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
