Object of the dissertation is prevention of hydraulic blow in the pressure tubes of the systems water supply by means of operating electric driver of pump unit. Purpose is the prevention of hydraulic blow at the short-term disconnecting of electrosupply of the electric motor of a pump unit with the help of additional electric motor, which places on one to the shaft with the driving electric motor and increases time of running out of the pump unit, that permits to realize successful self-start.
