Abstract
A gear pump is provided, for example, to convey liquid fuel in a fuel-operated heating apparatus. The gear pump includes a conveying chamber in a pump housing, a housing cover which closes the conveying chamber at least in regions, a conveying gear wheel which in the conveying chamber is rotatable about a rotation axis, a drive shaft which for co-rotation about the rotation axis is coupled to the conveying gear wheel, a first bearing unit for mounting the drive shaft on a first axial side of the conveying gear wheel, and a second bearing unit for mounting the drive shaft on a second axial side of the conveying gear wheel.
