Abstract: A heating circulating pump includes a pump housing (1) containing a pump impeller driven by an electric motor. The stator thereof is arranged in a motor housing (8) connected to the pump housing (1). A terminal box (12) is arranged on the motor housing (8), for electrically connecting the motor winding and for receiving electrical and/or electronic components of the motor control system. The terminal box (12) includes at least two parts that are bonded to each other, and the terminal box (12) is designed such that it is sealed from the motor and from the surrounding environment.

Abstract: A pump assembly includes a pump housing (2) and a stator housing (16), which is connected to the pump housing (2) and in which a wet-running electric motor with a can (18, 18?) is arranged. A plate-like bearing carrier (26, 26?) of sheet-material is arranged between the pump housing and the stator housing (16). The bearing carrier (26, 26?) includes a centering surface (40, 40?) in a manner distanced to its free peripheral edge, said centering surface coming into bearing contact on a corresponding contact surface (42) of the pump housing (2) in a manner such that the bearing carrier (26, 26?) with the can (18, 18?) is centered relative to the pump housing (2).

Abstract: A pump assembly with a stator housing (18), in whose inside a wet-running electric motor with a can (14) is arranged, and with a pump housing (2) connected to the stator housing (18). An annular shaped seal (22) is arranged between the stator housing (18) and a collar (34) of the can (14) on the one hand, and the pump housing (2) on the other hand.

Abstract: A heat circulation pump includes a pump housing (1) with a pump impeller arranged therein which is driven by an electric motor arranged in a motor housing (8) which axially connects to the pump housing (1). The heat circulation pump also includes a terminal box (12) which is axially connected to the motor housing (8) in order to receive electric and/or electronic components of the engine control. A plug or socket (34) of an electric plug connection is arranged on the outside of the terminal box (12) for the electric connection. The plug or socket (34) is/are axially offset with respect to the terminal box (12) and is/are arranged adjacent to the motor housing (8).

Abstract: A heat circulation pump includes a pump housing (1) with a pump impeller driven by an electric motor. The electric motor is arranged in a motor housing (8) connected to the pump housing (1). A plastic terminal box (12) is fixed to the motor housing (8) and houses electric and/or electronic components of the engine control and electrically connects the motor, a ground contact arranged on the motor housing (8), and a plug or a socket (34) arranged on the outside of the terminal box (12). The ground contact arranged on the motor housing is connected in an electrically conductive manner to a ground contact of the plug or socket (34) and to at least one conductor inside the terminal box (12). The electric connection between the ground contact arranged on the motor housing (8) and the ground contact of the plug or socket (34) is arranged outside of the terminal box (12).

Abstract: A heat circulation pump includes a pump housing (1) with a pump impeller arranged therein which is arranged in a motor housing (8) which is axially flange-mounted on the pump housing (1). The heat circulation pump also includes a terminal box (12) which is axially connected to the motor housing (8) in order to house electric and/or electronic components of the engine control and for electrically connecting the motor. The terminal box (12) protrudes, radially at least in sections, from the terminal box side end of the motor housing (8) and the terminal box has, in the axial direction, a right-angled outer contour with recesses (20) in the corner areas which are arranged in the axial extension of the screws (11). The flange (10) of the motor housing (8) are fixed to the pump housing (1) by the screws.

Abstract: A can of a drive motor is provided for a pump assembly, wherein the can (22) is manufactured at least partly of plastic (52). At least in a part of the can (22) the plastic (52) is reinforced by individual fibers (32) distributed in the plastic (52). The fibers (32) in at least one layer (35) of the can (32) are aligned in a defined manner in the peripheral direction with respect to the longitudinal axis (Z) of the can (22). A method for manufacturing such a can is also provided.
