A cover with a center axis for a pump assembly includes a plate. A center hole is formed in the plate and positioned on the center axis of the cover. A first edge of the plate extends between a first lobe and a second lobe, a second edge of the plate extends between the first lobe and a third lobe, and a third edge of the plate extends between the second lobe and the third lobe. The first, second, and third lobes each comprise a mounting boss with a thru-hole.
