Patent number: 11286941Abstract: A pump assembly (1) includes a rotor axle (45) extending along a rotor axis (R), an impeller (12) fixed to the rotor axle (45), a pump housing (11) accommodating the impeller (12), and a drive motor with a stator (17) and a rotor (51). The rotor (51) is fixed to the rotor axle (45) for driving the impeller (12). A rotor can (57) accommodates the rotor (51). The rotor can (57) includes a rotor can flange (63). An electronics housing (13) has a cap (21) including a first material (139) forming a front face (19) of the cap (21). The front face (19) extends essentially perpendicular to the rotor axis (R). The first material (139) is at least partially overmolded with a second material (141) at an inner side of the cap (21). The second material (141) is more heat-conductive than the first material (139).Type: GrantFiled: December 12, 2019Date of Patent: March 29, 2022Assignee: GRUNDFOS HOLDING A/SInventors: Erik Bundesen Svarre, Jan Plougmann, Therkel Damm, Jan Carøe Aarestrup, Klaus Vestergaard Kragelund, Morten Liengaard Svarre

A stator housing (13) accommodates the stator (17). The stator housing (13) is secured to the pump housing (11) by a bayonet ring (113). The bayonet ring (113) is resiliently spring-loaded for axially biasing the stator housing (13) towards the impeller (12) against the pump housing (11).Type: GrantFiled: December 12, 2019Date of Patent: August 10, 2021Assignee: GRUNDFOS HOLDING A/SInventors: Erik Bundesen Svarre, Jan Plougmann, Therkel Damm, Jan Carøe Aarestrup, Klaus Vestergaard Kragelund, Morten Liengaard Svarre

Publication number: 20200191161Abstract: A pump assembly (1) includes a rotor axle (45), an impeller (12) fixed to the rotor axle, and a pump housing (11) accommodating the impeller and defining a radial inner reference surface (71). A drive motor includes a stator (17) and a rotor (51). The rotor is fixed to the rotor axle for driving the impeller. A rotor can (57) accommodates the rotor and includes a rotor can flange (63). A stator housing (13) accommodates the stator. A radial bearing ring (47) is in sliding contact with the rotor axle. A bearing retainer (41) engages the radial bearing ring and centers the radial bearing ring with respect to the radial inner reference surface. The rotor can flange has a radial distance to the pump housing. The rotor can includes a radial inner centering surface (65) centered by radially abutting against a radial outer centering surface (67) of the bearing retainer.Type: ApplicationFiled: December 12, 2019Publication date: June 18, 2020Inventors: Erik Bundesen SVARRE, Jan PLOUGMANN, Therkel DAMM, Jan Carøe AARESTRUP, Klaus Vestergaard KRAGELUND, Morten Liengaard SVARRE

Publication number: 20200191158Abstract: A pump assembly includes a rotor axle, an impeller and a pump housing defining a radial inner reference surface. A drive motor includes a stator accommodated in stator housing and a rotor accommodated in a rotor can. A radial bearing ring is in sliding contact with the rotor axle. A bearing retainer engages the radial bearing ring and centers it with respect to the radial inner reference surface. A neck ring is coupled to the pump housing and has a circumferential wall section. The impeller is located axially between the bearing retainer and the neck ring. The circumferential wall section at least partially extends into the impeller or the impeller at least partially extends into the circumferential wall section. The circumferential wall section includes a cylindrical radial outer surface and a cylindrical radial inner surface. The radial outer surface is eccentric with respect to the radial inner surface.Type: ApplicationFiled: December 12, 2019Publication date: June 18, 2020Inventors: Erik Bundesen SVARRE, Jan PLOUGMANN, Therkel DAMM, Jan Carøe AARESTRUP, Klaus Vestergaard KRAGELUND, Morten Liengaard SVARRE

The pump housing (11) defines a first radial inner reference surface (71). A drive motor includes a stator (17) and a rotor (51) fixed to the rotor axle (45) for driving the impeller (12). A rotor can (57) accommodates the rotor (51) and includes a rotor can flange (63). A stator housing (13) accommodates the stator (17) and includes windings around a stator core (114). A first surface portion of the stator core (114) is overmolded with a first material (122) as an electrically insulating layer between the windings and the stator core (114). A second surface portion of the stator core (114) is overmolded with a second material (124) forming walls of the stator housing (13).Type: ApplicationFiled: December 12, 2019Publication date: June 18, 2020Inventors: Erik Bundesen SVARRE, Jan PLOUGMANN, Therkel DAMM, Jan Carøe AARESTRUP, Klaus Vestergaard KRAGELUND, Morten Liengaard SVARRE
