Pool pump with multiple outlets

1. A liquid pump for use with a fluid circulation system for a body of water, comprising:

a centrifugal pump assembly ( 120 ) having a casing ( 121 );

first and second outlet ports ( 122 , 123 ) in continuous fluid communication with an interior of said casing ( 121 ) without interruption and oriented in different directions from one another along the same plane;

an axially-extending aperture ( 124 ) arranged to receive a rotatable shaft powered by a motor ( 130 ); and

at least one cap ( 140 ) configured and dimensioned to engage and close one of said outlet ports ( 122 , 123 ) additionally oriented in different directions from said axially-extending aperture ( 124 ).

2. The liquid pump of claim 1 , wherein the centrifugal pump assembly is configured to mate with a strainer assembly on an inside side of the centrifugal pump assembly and mate with a motor on an outlet side of the centrifugal pump assembly.

3. The liquid pump of claim 1 wherein the first outlet and the second outlet are respectively oriented in vertical and horizontal positions.

4. The liquid pump of claim 1 wherein the first and second outlet ports each have internal and external threads.

5. The liquid pump of claim 4 wherein the cap is adapted to screw onto the outlet port.

6. The liquid pump of claim 1 wherein the centrifugal pump assembly includes a casing having an inner shell and an outer shell.

7. The liquid pump of claim 6 wherein the inner shell and outer shell are concentric and spaced apart from each other.

8. The liquid pump of claim 7 further including a housing extension adapted to cover a face of a motor.

9. The liquid pump of claim 8 wherein the housing extension includes a slot at a bottom of the housing extension.

10. The liquid pump of claim 1 wherein said liquid pump is connected to a water circulation system for a swimming pool.

11. The liquid pump of claim 1 , wherein the centrifugal pump assembly defines a channel positioned along an interior circumference and connected to each of the outlet ports.

12. The liquid pump of claim 1 wherein the first and second outlet ports ( 122 , 123 ) are oriented substantially perpendicularly to one another.

13. The liquid pump of claim 1 wherein the first and second outlet ports ( 122 , 123 ) extend tangentially outwardly from the interior of said casing ( 121 ).

14. The liquid pump of claim 1 , wherein said casing ( 121 ) additionally comprises a channel ( 127 ) positioned around a circumference of the interior of said casing ( 121 ) and communicating with both said outlet ports ( 122 , 123 ).

15. A method for selecting the direction of fluid outflow from a centrifugal pump comprising:

providing a liquid pump including

a strainer assembly,

a centrifugal pump assembly having at least first and second outlet ports oriented in different directions,

a motor, and,

at least one cap configured and dimensioned to engage and close an outlet port,

wherein the first outlet and the second outlet ports ( 122 , 123 ) in continuous fluid communication with an interior of a casing ( 121 ) of the pump assembly ( 120 ) and are respectively oriented in vertical and horizontal positions;

selecting the vertical or horizontal direction of liquid outflow; and

affixing the cap to the outlet port associated with the non-selected direction of liquid outflow to prevent the outflow of liquid therethrough,

with the outlet ports ( 122 , 123 ) additionally oriented in different directions from an axially-extending aperture ( 124 ) to receive a rotatable shaft powered by the motor ( 130 ).

16. The method of claim 15 wherein the first and second outlet ports are each threaded and the step of affixing the cap to the outlet port comprises screwing the cap onto the end of the non-selected outlet port.
