    Abstract: The present disclosure refers to a pump (1) comprising



    a rotor shaft (13) extending along a rotor axis (R),
    a bearing body (19) circumferentially encompassing the rotor shaft (13) and comprising a radially outer bearing surface (32), and
    a locking ring (25) circumferentially encompassing the rotor shaft (13) and limiting an axial movement of the bearing body (19) relative to the rotor shaft (13),

    wherein the locking ring (25) comprises at least two radially inwardly protruding teeth (49, 51, 53, 55), wherein the locking ring (25) is radially expandable from a locking state to a mounting state against an elastic restoring force of the locking ring (25), wherein the locking ring (25) is, in the mounting state, positionable at a desired axial position on the rotor shaft (13), wherein the teeth (49, 51, 53, 55) are configured to press, in the locking state, against a radial outer surface (31) of the rotor shaft (13) by the elastic restoring force of the locking ring (25).

    Abstract: A method for controlling operation of a fluid transport system by applying a self-learning control process. The method includes: receiving obtained values of input signals during operation of the system during a first period of time, which is controlled by a predetermined control process, automatically selecting a subset of the input signals based on the received obtained values of the input signals, receiving obtained values of at least the selected subset of input signals during a second period of time, which is controlled by applying the self-learning control process, which is configured to control operation based only on the selected subset of input signals, and wherein applying the self-learning control process includes updating the self-learning control process based on the received obtained values of the selected subset of the input signals and based on at least an approximation of a performance indicator function.

    Abstract: A hydraulic construction unit for a heating facility or air-conditioning facility, includes a return connection (20) and a first feed connection (16) for a heating circuit (6), with a heat source outlet (12) fluid conducting connected to the return connection. A heat source inlet (14) is fluid conducting connected to the first feed connection and to a circulation pump assembly (28) in a flow path between the return connection and the heat source outlet (12) or in a flow path between the heat source inlet and the first feed connection. A second feed connection (18) for a second heating circuit (8), is fluid conducting connected to the heat source inlet and to the return connection. A mixing valve (54) is arranged in a flow path from the heat source inlet to the second feed connection and/or in a flow path from the return connection to the second feed connection.

    Abstract: The invention relates to a method of manufacturing a composite component (21) having a varying electric resistivity along a longitudinal direction of the component. At least a first paste (10a) having a first composition, and at least a second paste (10b) having a second composition are prepared. The pastes are transferred into a supply chamber (35) of a processing equipment (31), such as an extruder. A green body (20) is shaped by forcing the pastes from the supply chamber through a die (32), and the green body is then sintered or oxidized to form the composite component. The pastes may comprise metal powder, ceramic powder, and binder. The varying electric resistivity may be due to variations in one or more of the following parameters: the volume ratio between the metal powder and the ceramic powder, the size of the ceramic particles, and the type of the ceramic material.
