Abstract: A pump unit includes a pump housing and a rotor in the pump housing. The pump unit contactless magnetic levitating and driving the rotor. The pump housing has a bottom part and a cover, the bottom part having a cylindrical cup to receive the rotor and a substantially ring-shaped first sealing surface for a sealing interaction with the cover. The cover has a substantially ring-shaped second sealing surface for a sealing interaction with the first sealing surface. One of the first and second sealing surfaces is a ribbed surface with a radial sealing rib, which extends in the circumferential direction along the entire sealing surface, while the other of the first and second sealing surfaces is a smooth surface.

Abstract: An eductor for mixing a primary fluid with a flowable secondary substance includes a primary inlet for the primary fluid, a secondary inlet for the secondary substance, an outlet and a suction chamber, A converging inlet nozzle is provided, which is arranged between the primary inlet and the suction chamber so that the primary fluid can flow from the primary inlet into the suction chamber. An outlet nozzle is provided between the suction chamber and the outlet, through which the primary fluid and the secondary substance can flow to the outlet, and the secondary inlet is provided at the suction chamber so that the secondary substance can flow from the secondary inlet into the suction chamber.

Abstract: A mixing system includes an eductor, a supply connection connected to a reservoir for a primary fluid, a discharge connection, a storage container for a secondary substance, a centrifugal pump to convey the primary fluid through the supply connection, and a controller to control the centrifugal pump. The eductor includes a primary inlet for the primary fluid, a secondary inlet for the secondary substance, an outlet for a mixed fluid, and a suction chamber to suck the secondary substance, the primary inlet connected to the supply connection so that the primary fluid can flow from the reservoir into the eductor and the outlet connected to the discharge connection so that the mixed fluid can be discharged from the eductor. The secondary inlet is at the suction chamber and connected to the storage container. A closing device is between the suction chamber and the storage container.
