Abstract: Embodiments of the invention provide a fill valve for use in a livewell of a boat. The fill valve includes an intake and a valve housing coupled to the intake. The valve housing includes a rounded half-sphere shaped front wall coupled to a substantially flat back wall. The front wall includes one or more inlet openings in fluid communication with the intake. The fill valve also includes a valve switch positioned in the valve housing to switch between a first position allowing fluid communication between the inlet openings and the intake and a second position providing a substantially liquid-tight seal between the inlet openings and the intake.

Abstract: A bilge pump having a mounting member adapted to be mounted to a vessel and a base movably engageable with the mounting member and positionable in at least two positions relative to the mounting member. A housing is releasably coupled to the base and defines a cavity for receiving a motor. A locking ring is engageable with the motor and the housing to secure the motor in the cavity while allowing the motor to be movable with respect to the housing. The cavity in the housing communicates with an outlet portion defining a socket. An outlet nozzle having an outlet end is movably received in the socket so that the outlet end can be moved relative to the housing. These features can be employed individually or in combination to make the bilge pump highly adaptable, thereby facilitating installation.

Abstract: A pump including a pump housing, a fluid inlet, a fluid outlet, a pumping chamber in fluid communication with both the fluid inlet and the fluid outlet, a motor for pumping a working fluid, and a plate that is at least partially constructed of a heat conductive material and that at least partially defines the pumping chamber. The plate can transfer heat from the motor to the working fluid in the pumping chamber.

Abstract: Pumps, for example, bilge pumps, comprise a pump housing including an inlet and an outlet, a motor and an impeller assembly coupled to the motor for pumping liquid which passes through the outlet. The motor is advantageously cooled by pumped liquid while being protected from the pumped liquid. Further, the motor is turned on and off in response to actual operating conditions, thereby increasing pump life and reducing overall power consumption. The pump provides contoured facing surfaces which provide a dynamically efficient flow path for the pumped liquid. In addition, a switch housing is preferably provided to allow liquid to contact an activator assembly which turns the motor on.

Abstract: A pump includes a housing having at least a first pumping chamber, an inlet, an inlet passage leading from the inlet to the pumping chamber, an outlet and an outlet passage leading from the pumping chamber to the outlet. A first pumping member is movable in the pumping chamber on an intake stroke whereby fluid from the inlet passage is drawn into the pumping chamber and on a discharge stroke whereby fluid in the pumping chamber is discharged into the outlet passage. A drive is provided for moving the pumping member on the intake and discharge strokes. A bypass passage leads from a location in the outlet passage to a location in the inlet passage. A bypass valve is provided and is movable in response to the pressure from the outlet passage and substantially independent of the pressure from the inlet passage between an open position in which fluid flows through the bypass passage and a closed position in which fluid is prevented from flowing through the bypass passage.
