Abstract: Disclosed are improved locking mechanisms for vessels, including both pressure and vacuum/suction vessels, used in swimming pool and spa equipment. These improved locking mechanisms provide a more robust, reliable seal between the lid and the body of the vessel, and include features that make moving the vessel between its sealed and unsealed positions easier. More specifically, the locking mechanisms include features that allow the lid to move into its sealed position when the locking ring is rotated relative to the vessel in a first direction, and that allow the lid to release from its sealed position and lift off the body when the locking ring is rotated relative to the vessel in a second direction opposite the first direction.

Abstract: Disclosed are pumps designed to make priming more efficient and therefore reduce priming time. The disclosed pumps include one or more deflection structures (40) that prevent fluid moving through a diffuser (20) of the pump from continuing in a circular path (44) and instead divert the fluid in a different direction that leads directly to an outlet of the pump. This deflection reduces air bubble accumulation inside the pump while priming and makes it easier for air to escape through the pump outlet. Making it easier for air to escape the pump outlet ultimately allows air to escape the pump faster during priming, reducing back pressure caused by trapped air pockets inside the pump and improving priming performance.
