Patent number: 10273959Abstract: A pump assembly has an electric drive motor which is designed as a canned motor which has a bearing (22) in the interior of motor can (14), on which a motor shaft (20) is supported. The bearing (22) has an outer diameter that is smaller than an inside diameter of the motor can (14) and the bearing (22) in the interior of the motor can (14) is supported on a bearing holder (24) which has multiple steps (40) extending traversely to an inner circumference of the motor can (14).Type: GrantFiled: December 14, 2012Date of Patent: April 30, 2019Assignee: Grundfos Holding a/sInventor: Kåre Iversen

Patent number: 10184574Abstract: A heating or cooling installation control valve includes a movable valve element which is arranged in a valve space (8), as well as at least two connection channels (24, 26) which each have a first end in fluidic connection with the valve space (8) and have an opposite second end (A, B) for connection to a fluid-leading component. A sealing element (18) is arranged in at least one of the connection channels (24, 26) at a first end thereof. The sealing element is in contact with the valve element (6). The at least one connection channel (24, 26), in which the sealing element (18) is arranged, in addition to the second end (A, B), includes an assembly opening, through which the sealing element (18) can be inserted into the connection channel (24) and removed from of the connection channel (24).Type: GrantFiled: December 22, 2015Date of Patent: January 22, 2019Assignee: GRUNDFOS HOLDING A/SInventors: Kåre Iversen, Torben Heilskov Overgaard

Patent number: 9885665Abstract: The device serves for the qualitative and quantitative detection of particles in a fluid and includes a light source (1), an optical sensor (2) and a sample carrier (4) which is arranged therebetween and which is for receiving fluid to be examined. The sample carrier is (4) movable relative at least to the sensor (2) and is connectable via a fluid inlet (9) to a conduit (11) for feeding the fluid, and via a fluid outlet (10) to a conduit (12) for the discharge of fluid. The sample carrier (4) is exchangeably arranged in a receiver of the device, so that this sample carrier can be replaced by another one in a rapid and simple manner when the sample carrier (4) is contaminated.Type: GrantFiled: September 28, 2015Date of Patent: February 6, 2018Assignee: GRUNDFOS HOLDING A/SInventors: Kåre Iversen, Mathis Dahlqvist, Christian Guldbæk Smith

Publication number: 20170356834Abstract: A method for the quantitative and/or qualitative detection of particles in fluid, with which the fluid to be examined is introduced into a beam path of an optical device, between at least one light source and the image acquisition sensor with a matrix of light-sensitive cells. Pixel values of the cells are detected and the distribution of the pixel values is at least partly determined. The pixel value or values which have been determined most often are used as a value or average value for a background signal. A signal is outputted or the method is interrupted, on reaching a maximal permissible value for the background signal.Type: ApplicationFiled: November 30, 2015Publication date: December 14, 2017Applicant: Grundfos Holding A/SInventors: Kåre IVERSEN, Christian GULDBÆK SMITH, Mathis DAHLQVIST

Patent number: 9746857Abstract: A heating installation or cooling installation mixing device has a valve housing (14) including a first flow path from a first connection (A-B) to a second connection (A), and a second flow path from the first connection (A-B) to a third connection (B). A movable valve element (24), arranged inside the valve housing (14) in the flow paths, is configured to vary a ratio of cross sections of the flow paths. A valve element drive (36) is arranged on the valve housing (14) and includes an internal control device (38) for movement control of the drive (36) and includes a first communication interface (44) for external control device (40) communication and a second communication interface (46). An internal sensor (48, 50) is arranged in or on the valve housing (14) and is connected to the first communication interface (44) for transmitting a sensor signal to the external control device (40).Type: GrantFiled: December 21, 2015Date of Patent: August 29, 2017Assignee: GRUNDFOS MANAGEMENT A/SInventor: Kåre Iversen

Publication number: 20170122326Abstract: A centrifugal pump assembly includes an electric motor (2) driving a centrifugal pump (1) and includes an electronics casing (8). In the electronics casing (8), the control electronics (10, 11) for the pump and motor are integrated. A device for detecting particles in a fluid fed via a bypass (6, 7) of a delivery conduit (3) is also in the electronics casing (8).Type: ApplicationFiled: November 2, 2016Publication date: May 4, 2017Inventors: Mathis DAHLQVIST, Christian Guldbæk SMITH, Kåre IVERSEN
