Embodiment Construction
[0024] The electric coolant pump 10 comprises a multipart pump housing 12 with a pumping chamber cover element 14 , a motor chamber cover element 16 and a partition side wall 18 extending essentially in a radial plane. In the present embodiment of the invention, the partition side wall 18 is made of a material with high thermal conductivity, for example aluminum. The pumping chamber cover element 14 and the dividing side wall 18 define a pumping chamber 20 which is filled with coolant during pump operation. The pumping chamber 20 comprises a radially inner pump inlet 22 , a radially outer pump outlet 24 and a pump volute 26 extending in a radial plane from downstream of the pump inlet 22 to the pump outlet 24 . The pump inlet 22 extends substantially in the axial motor direction, and the pump outlet 24 extends substantially in a radial plane, so that the pump inlet 22 is arranged substantially perpendicularly with respect to the pump outlet 24 . The flow cross section of the ...
