Abstract
An impeller for a delivery pump in which profiled section (14) comprising webs (15) is located on the outer periphery of an impeller (4) for a feed pump (2) that is configured as a side channel pump. The webs (15) are arranged at an ascending incline, viewed in the rotational direction of the impeller (4) from the designated pressure side to the designated intake side. This permits flow losses between the radial external region of the impeller (4) and the housing parts (6, 7) of the feed pump (2) to be maintained at a particularly low level.
Claims1
An impeller for a delivery pump which is constructed as a side channel pump is provided for delivering fuel in a fuel container and which, at its ends, in each case has a ring of guide vanes bounding vane chambers spaced apart from its radially outer rim and is provided to be arranged between housing parts of the delivery pump, wherein a profiled section having radially projecting webs distributed irregularly over the periphery is arranged at the radially outer rim.
