Rotary pump for use in hydrodynamic systems for supplying water, has suction chamber and pressure chamber, which lies behind suction chamber in flow direction and is separated from suction chamber in axial direction by separating element

摘要

The rotary pump has a pump housing with a housing inlet opening, a housing outlet opening and a structural element for liquid supply arranged between the housing inlet opening and the housing outlet opening. The structural element is driven by a motor and rotates about an axis. The rotary pump has a suction chamber (6) and a pressure chamber, which lies behind the suction chamber in a flow direction and is separated from the suction chamber in an axial direction through a separating element. The pressure chamber rotates with the rotating structural element.
