    Abstract: An asymmetrical bearing is disclosed for use in a gear pump. The bearing may have first and second opposing faces, and first and second bores in communication with the first and second opposing faces. The first and second bores may be configured to receive first and second shafts of a gear pump. The bearing may have a first flat side surface and a second curved side surface, where the second curved side surface includes first and second curved portions associated with the first and second bores, respectively. The first and second faces and the first flat side surface may also include a plurality of grooves configured to direct a flow of process fluid over the bearing during operation of the pump. Self-aligning features can be provided on one or more sealing elements to ensure desired alignment of the sealing components during assembly. Other embodiments are described and claimed.
