Description	At the pumps of low specific speed it is possible, that near the point of zero discharge the Q-Y characteristic is unstable. This phenomenon of unstable Q-Y characteristic causes big pressures and discharge pulsations, which are characterized by self- excited oscillations of the systems. It is not recommended to run the pump between points of unstable characteristic. For this pump it is impossible to work in exacting operations (atomic power stations, heating plant stations, chemical industry). The stability conditions (Y,Q) are analyzed on the basis of dissipation function. It is assumed, that power input of the pump is linear function of the discharge.
