Abstract: Disclosed are pumps designed to make priming more efficient and therefore reduce priming time. The disclosed pumps include one or more deflection structures that prevent fluid moving through a diffuser of the pump from continuing in a circular path 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.

Abstract: Assemblies designed to facilitate detection of water flow in low water flow situations. In some embodiments, the assembly includes a channel that narrows from an inlet end of the assembly to an outlet end of the assembly to increase the velocity of water flowing through the channel. In some embodiments, the assembly may also include a water delivery mechanism that delivers water flowing through the channel to a flow sensor and enables the detection of water flow, even in low flow situations.

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: A seal member for creating an adequate sealing engagement between two bodies. The seal member may have a closed loop shape, a plurality of engagement surfaces and a plurality of lobes formed on the engagement surfaces. The lobes may contact a sealing surface on a body to aid in creating an adequate seal between two bodies.

Abstract: A pump mount base for a filter/pump assembly in a pool or spa fluid handling system allows a user to adjust the height of the filter/pump assembly and thus its fluid inlets and fluid outlets. This adjustability allows the user to choose from a variety of replacement assemblies rather than being forced to select the same filter/pump assembly previously or originally used in the system. The height of the filter/pump assembly may be further altered by the engagement of shims, which may be positioned by pins in the bottom surface of the shim that engage corresponding apertures formed in an upper support surface of the pump mount base. The shims may be formed integrally with the pump mount base in the molding process by which the base is formed, and/or the shims may be provided separately.
