Embodiments of the invention provide a pump assembly including a pump, a motor, and a baseplate. The pump includes a valve housing and an upper housing with a ring to separate an inlet chamber from an outlet chamber. An o-ring is positioned between raised outer walls of the ring and secured by a cutout of the valve housing.
