<p>The pump has a pump body (11) with a radial flow impeller (12) mounted on a transmission shaft (15). A driving unit drives the shaft in rotation and has a contact surface driven in rotation by a transmission unit. The surface is integrated to the shaft and an outer cage (13b) of a rolling bearing (13). The rolling bearing has an inner cage mounted on a bearing (11a) of the body by being integrated to the pump. The contact surface is constituted by an outer surface of the outer cage.</p> |
