Patent number: 10385860Abstract: A pump arrangement, in particular a magnetic coupling pump arrangement, includes a pump housing having an interior, a split case which hermetically seals a chamber surrounded by the split case from the interior formed by the pump housing, an impeller shaft with an impeller thereon which can be driven in a rotatable manner about a rotational axis, an inner rotor arranged at an end of the impeller shaft opposite the impeller end, an outer rotor which interacts with the inner rotor, and an adapter element which connects the split case to the pump housing or to a component paired with the pump housing, in particular a housing cover. The adapter element includes a mounting flange which rests against a support surface of the pump housing, in particular of the housing cover (4), on a face adjacent to the interior.Type: GrantFiled: May 19, 2014Date of Patent: August 20, 2019Assignee: KSB AktiengesellschaftInventors: Patrick Drechsel, Markus Lay

Patent number: 10253783Abstract: A pump arrangement, in particular a magnetic clutch pump arrangement, is provided. The pump arrangement includes a pump housing containing an impeller shaft, an impeller, a casing cover adjacent to the impeller and supporting a plain bearing arrangement. The pump arrangement also includes a containment shell which seals an enclosed chamber within the inner chamber of the pump housing. The plain bearing arrangement includes first and second bearing sleeves connected to the impeller shaft, a first bearing bush which cooperates with the first bearing sleeve via a radial bearing surface and is connected to the pump housing or to a component secured to the pump housing a second bearing bush which cooperates with the second bearing sleeve via a radial bearing surface and is connected to the pump housing or to a component secured to the pump housing, and a retainer ring mounted between the first and second bearing sleeves.Type: GrantFiled: April 29, 2014Date of Patent: April 9, 2019Assignee: KSB AktiengesellschaftInventors: Patrick Drechsel, Markus Lay
