Abstract (en)
[origin: EP2796722A1] The invention refers to an automotive electrical coolant pump (10) comprising a pump section (12) with an pump wheel (40) and a motor section (14) with a motor rotor (52) and a motor stator (50). The pump housing comprises a pump section housing (42) and a separate motor section housing (44) which is fixed to the pump section housing (42). The pump section housing (42) comprises an axial coolant inlet (24) and a tangential coolant outlet (26). The fixation of the pump section housing (42) with the motor section housing (44) is provided by a bordering arrangement (20). The bordering arrangement (20) is defined by a circular fixation bulge (36) at the axial end of one section housing (42) and a circular bordering ring (34) at the axial end of the other section housing (44). The bordering ring (34) embraces the fixation bulge (36). The fixation bulge (36) is provided with at least one chamfer depression (37) and a bordering tongue (38) of the bordering ring (34) is projecting into the chamfer depression (37).
