Description: Runner resonant frequency calculated taking into account the additional support and damping caused by the effect of the fluid in the impeller; Name: crit speed (wet)
Description: Rotor resonant frequency calculated assuming that the rotor is supported only at its bearings and that the bearings are of infinite stiffness ; Name: Dry critical 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
