主权项 1. A centrifugal pump assembly with a device for separating gas from a fluid to be delivered, which is arranged on a suction side, wherein the gas separation device comprises an impact body arranged entirely in a suction-side flow path of the fluid to be delivered, and which is arranged on a housing side of the gas separation device at a distance from a suction port of the pump, wherein an assembly housing comprises a pump housing accommodating an impeller, with the suction port, and a gas separation housing connecting to the suction port, which are separated by an intermediate wall, and the impact body is arranged within the gas separation housing and comprises an impact surface which extends radially or parallel to a radial line and parallel to an impeller axis, wherein the impact body comprises a rib connected to the gas separation housing on at least at one side, and wherein a float housing is provided for incorporating a degassing valve, and which peripherally passes through a wall of the gas separation housing, wherein a housing part located within the gas separation housing is provided with through-holes, and a housing part located outside the gas separation housing is designed in a closed manner.
