A liquid pump and controller with separate pump activation and deactivation mechanisms that are both closed detector devices is provided. The pump activation mechanism includes a float device that activates a pump motor when water within a housing of the pump reaches a high water level. The pump deactivation mechanism includes a sensor that detects the load on the pump motor and deactivates it when the sensed load indicates that the water within the pump housing has reached a low water level.

A removable live well pump including a pump housing having a first housing portion and a second housing portion, a pump intake pipe attached to the second housing portion, a pump assembly attached to the first portion, and a snap fit locking mechanism including a pair of first locking portions located on the first housing portion and a second locking portion located on the second housing portion. The first locking portions are located diametrically opposite each other. The first locking portions are movable between a first locked position, in which the first locking portions engage the second locking portion, and a second unlocked position, in which the first locking portions disengage from the second locking portion. Moving a top portion of each of the first locking portions radially inwardly moves the first locking portions from the first locked position to the second unlocked position.

A pump for use in marine environments including a pump housing having a cap portion and a main portion, a pump intake pipe attached to the main portion, a pump assembly attached to the cap portion is described. A pair of clips extending from said cap portion extend over a pair of raised surfaces on said main portion. Rotation of the cap portion moves said clips from a low end of the raised surfaces to a high end, thereby locking the cap portion to the main portion. In another embodiment, a locking ring fits over the junction between the cap portion and the main portion. The ring includes an inwardly directed upper flange and a plurality of inwardly directed protrusions on a lower extent. The ring fits over the cap portion such that a flange from the motor housing and one or more flanges from the main portion are caught between the upper flanges and the protrusions of the locking ring. The pump may be a removable live well pump or a bilge pump.
