A central distribution unit (CDU) for circulating coolant is disclosed. The CDU may operate under negative pressure and can have a number of operation modes including: normal operation, pump priming, fill, drain, purge and vacuum test. The CDU includes various valves, pumps and sensors, the placement and actuation of which transitions the CDU into the various modes.

The present invention relates to a laundry-care appliance (100) comprising a metering system (105) for metering a first liquid substance and a second liquid substance, wherein the metering system (105) comprises a first storage container (107) for providing the first liquid substance, a second storage container (109) for providing the second liquid substance, and a pump unit (112) which comprises a first pump head (113) and a second pump head (115). The metering system (105) comprises a common drive (129) for driving the first pump head (113) and the second pump head (115), wherein the common drive (129) can be driven in a first drive direction (137) and in a second drive direction (139). The first pump head (113) is designed in the case of the first drive direction (137) of the common drive (129) to convey the first liquid substance in a first conveying direction (149) from the first storage container (107). The second pump head (115) is designed in the case of the second drive direction (139) of the common drive (129) to convey the second liquid substance in a second conveyor direction (153) from the second storage container (109).

An illustrative embodiment of the present disclosure includes a pump having a rotor and a plurality of vanes. The rotor is attached to a motor that rotates it in first and second directions and is located in a cavity. The plurality of vanes are each pivotally coupled to the rotor so as the rotor rotates, the vanes selectively push fluid from an inlet port out through an outlet port. The plurality of vanes each have an end selected from the group consisting of a lobe, no lobe, and a rod located in the lobe. Each of the plurality of vanes also includes a pivot pin configured to fit in a corresponding receptacle located in the rotor so that each of the plurality of vanes is pivotable with respect to the rotor inside the cavity.
