A livewell/baitwell pump includes a replaceable cartridge for arranging in a pump cartridge body of a pump cartridge assembly. The replaceable cartridge is rotatably coupled to the pump cartridge body and locked in place by a pre-loaded locking lever that securely engages a locking edge of the pump cartridge body and holds the replaceable cartridge therein. The pre-loaded locking lever is spring-loaded and pivotally arranged on the replaceable cartridge to snap into place and lock the replaceable cartridge when the locking lever is rotated passed the locking edge, so that the replaceable cartridge may be installed in the cartridge body using one hand. In operation, when the replaceable cartridge is rotated into the pump-cartridge body to a desired locking position, the pre-loaded locking lever engages the locking edge of the pump cartridge body. The locking edge is formed on an annular rim on the pump cartridge body as a raised edge. Moreover, the pre-loaded locking lever is pressed inwardly, then twisted in order to remove the replaceable cartridge from the pump cartridge body, so that the replaceable cartridge may be removed from the cartridge body using one hand. The pre-loaded locking lever includes a bias member, such as a spring or other suitable elastic member or material, for continuously urging the pre-loaded locking lever against the replaceable cartridge.

Livewell/baitwell pump featuring replaceable locking cartridge feature

A livewell/baitwell pump for installing in a boat or other suitable vessel or apparatus, the pump comprising a pump cartridge assembly having a cartridge body with one or more flexible cantilever snap tabs and with a discharge hose; a pickup tube having an interior cavity with one or more undercuts and with a pickup tube; and each cantilever snap tab of the cartridge body being releasably coupled to a respective undercut of the pickup tube when the cartridge body is inserted into the interior cavity for permitting rotation of the pickup tube and the cartridge body in relation to one another for quickly and easily coupling the discharge hose and the pickup tube in any direction to corresponding hosing or tubing during installation of the pump in the boat or other suitable vessel or apparatus. The pump further comprises an anti-rotation locking ring that permits the rotation of the pickup tube to a desired orientation in relation to the pump cartridge assembly when the anti-rotation locking ring in a first position, and that prevents rotation of the pickup tube once in the desired direction in relation to the pump cartridge assembly when in a second position.
