Abstract
A system for a live well fill pump fulfills the dual goals of keeping the intermittently operating fill pump primed and dissolving gasses in water sourced by the fill pump. A check valve in a water intake assembly cooperates with a check valve in a pump output assembly to keep the fill pump primed in between intermittent pumping operations. Water flowing out of the fill pump through the second check valve undergoes a pressure differential and turbulence. A gas delivery system directs the turbulent water through the output conduit or chamber to dissolve the gas in the water. The gas-saturated water is released through the water outlet into the container.
Claims35
A system for keeping a fill pump primed between intermittent operations of the fill pump and for dissolving gasses in water sourced by the fill pump from a body of water located below a container, the system comprising:
- (a) a water intake assembly for the fill pump, the water intake assembly having a first check valve and an input conduit, wherein water flows through the first check valve and the input conduit into the fill pump;
- (b) a pump output assembly having a second check valve and an output conduit or chamber comprising a water outlet, the output conduit or chamber carrying water from the pump through the second check valve to the water outlet, the pump output assembly creating a pressure differential and turbulence in water flowing out of the fill pump;
- and
- (c) a gas delivery system, wherein the output conduit or chamber is structured to receive a gas and for turbulent water to flow through the gas in the output conduit or chamber to dissolve the gas in the water;
- wherein gas-saturated water is released through the water outlet into the container;
- and
- wherein the first and second check valves keep the fill pump primed after the fill pump ceases pumping.
A system for keeping a fill pump primed between intermittent operations of the fill pump and for dissolving gasses in water sourced by the fill pump from a body of water located below a container, the system comprising:
- (a) a water intake assembly for the fill pump, the water intake assembly having a first check valve, wherein water flows through the first check valve into the fill pump;
- (b) a pump output assembly having a second check valve and an output conduit or chamber comprising a water outlet, wherein water flowing out of the fill pump through the second check valve creates a pressure differential and turbulence in the output conduit or chamber;
- and
- (c) a gas delivery system comprising a gas line through which a gas is introduced to the pump output assembly, wherein the gas line is in communication with an air port and water flow through the second check valve draws ambient air through the air port into the output conduit or chamber and dissolves the gas in the water;
- wherein gas-saturated water is released through the water outlet into the container;
- and
- wherein the first and second check valves keep the fill pump primed after the fill pump ceases pumping.
A system for keeping a fill pump primed between intermittent operations of the fill pump and for dissolving gasses in water sourced through a water intake assembly by the fill pump from a body of water located below a container, wherein the water intake assembly has a first check valve and an input conduit and water flows through the first check valve and the input conduit into the fill pump, the system comprising:
- (a) a pump output assembly having a second check valve and an output conduit, the output conduit carrying water from the fill pump through the second check valve, the pump output assembly creating a pressure differential and turbulence in water flowing out of the fill pump;
- (b) a mixing chamber having a water outlet and including at least one member selected from the group consisting of a mixing medium, bubble trap, impingement medium, impingement plate, diverter plate, diverter device, and distributor;
- and
- (c) a gas delivery system, wherein the output conduit or mixing chamber is structured to receive a gas and for turbulent water to flow through the gas in the output conduit or mixing chamber to dissolve the gas in the water;
- wherein gas-saturated water is released through the water outlet into the container;
- and
- wherein the first and second check valves keep the fill pump primed after the fill pump ceases pumping.
A system for keeping a fill pump primed between intermittent operations of the fill pump for a portable live well, the fill pump intermittently inputting water from a body of water located below the live well into the live well, the system comprising:
- (a) a water intake assembly for the fill pump, the water intake assembly having an input conduit, a filter, and a first check valve within the input conduit, wherein water flows through the first check valve into the fill pump;
- and
- (b) a pump output assembly having a second check valve, wherein water flows out of the fill pump through the second check valve, the pump output assembly creating a pressure differential and turbulence in the water flowing to the live well;
- wherein the first and second check valves keep the fill pump primed after the fill pump ceases pumping.
