Booster pump system for pool applications
View Patent ↗Assemblies and methods for a booster pump used in a pool cleaning/filtration system are provided. An exemplary booster pump assembly is adapted to increase the water pressure of water flow for use in a pool cleaning system. The booster pump includes a front housing defining a substantially circular geometry having an inlet positioned substantially in the center of the front housing and extending axially outward with respect to the front housing. The booster pump also includes an outlet extending substantially laterally with respect to the front housing. The front housing and the rear housing form an enclosure for positioning of an impeller. The inlet and the outlet are each coupled to conduits having substantially similar flow diameters, and the water passing through the outlet at an increased water pressure is sufficient to make operable a positive pressure pool cleaner. Advantageous support structures and drain plug configurations are also provided.
1. A booster pump assembly adapted to increase the pressure of water flow for use in a pool cleaning system, the booster pump assembly comprising:
(a) a front housing defining a substantially circular geometry, the front housing including:

wherein the motor is adapted to drive an internal impeller system positioned within the enclosure formed by the front housing and the rear housing, the impeller system being adapted to increase pressure of the water flowing through the enclosure and exiting through the outlet; and
wherein the inlet is coupled to a first conduit system having a flow diameter that is substantially equivalent to the inlet diameter, and the outlet is coupled to a second conduit system having a flow diameter that is substantially equivalent to the outlet diameter.
2. An assembly according to claim 1 , wherein the inlet diameter, the outlet diameter, the first conduit and the second conduit each define a flow diameter of about 1½ inches.
3. An assembly according to claim 1 , wherein the first conduit and the second conduit are selected from the group consisting of a pipe, a hose, a tube and combinations thereof.
4. An assembly according to claim 1 , wherein the front housing is adjustably rotatable to allow a plurality of radial orientations of the outlet with respect to the inlet.
5. An assembly according to claim 4 , wherein the rear housing and the drain plug remain substantially stationary regardless of the radial orientation of the front housing.
6. An assembly according to claim 1 , wherein coupling of the inlet and the outlet to the first and second conduit, respectively, are facilitated by union connectors.
7. An assembly according to claim 1 , further comprising a handle having a front portion that is mounted with respect to and extends upward from the rear housing, and a rear portion that is mounted with respect to and extends upward from the motor.
8. A booster pump assembly adapted to increase the pressure of water flow for use in a pool cleaning system, the booster pump assembly comprising:
(a) a front housing defining a substantially circular geometry, the front housing including:
(i) an inlet positioned substantially in the center of the front housing extending axially outward with respect to the front housing and defining an inlet diameter; and
(ii) an outlet extending substantially laterally with respect to the front housing and defining an outlet diameter;
(b) a rear housing forming an enclosure with the front housing;
(c) a motor positioned rearwardly with respect to the rear housing;
wherein the inlet is adapted to allow water to flow into the enclosure formed by the front housing and the rear housing, and the outlet is adapted to allow water to exit the enclosure formed by the front housing and the rear housing;
wherein the motor is adapted to drive an internal impeller system positioned within the enclosure formed by the front housing and the rear housing, the impeller system being adapted to increase pressure of the water flowing through the enclosure and exiting through the outlet; and
wherein the inlet is coupled to a first conduit system having a flow diameter that is substantially equivalent to the inlet diameter, and the outlet is coupled to a second conduit system having a flow diameter that is substantially equivalent to the outlet diameter,
wherein the motor is mounted with respect to the rear housing with a square flange.
9. An assembly according to claim 8 , wherein the square flange is mounted with respect to the rear housing by at least one mounting member.
10. A booster pump assembly adapted to increase the pressure of water flow for use in a pool cleaning system, the booster pump assembly comprising:
(a) a front housing defining a substantially circular geometry, the front housing including:
(i) an inlet positioned substantially in the center of the front housing extending axially outward with respect to the front housing and defining an inlet diameter; and
(ii) an outlet extending substantially laterally with respect to the front housing and defining an outlet diameter;
(b) a rear housing forming an enclosure with the front housing;
(c) a motor positioned rearwardly with respect to the rear housing,
wherein the inlet is adapted to allow water to flow into the enclosure formed by the front housing and the rear housing, and the outlet is adapted to allow water to exit the enclosure formed by the front housing and the rear housing;
wherein the motor is adapted to drive an internal impeller system positioned within the enclosure formed by the front housing and the rear housing, the impeller system being adapted to increase pressure of the water flowing through the enclosure and exiting through the outlet; and
wherein the inlet is coupled to a first conduit system having a flow diameter that is substantially equivalent to the inlet diameter, and the outlet is coupled to a second conduit system having a flow diameter that is substantially equivalent to the outlet diameter,
(d) a support structure adapted to provide structural support to the front housing, rear housing and motor, wherein the support structure includes: (i) a front side support member configured and dimensioned to provide support to at least the rear housing; and (ii) a rear side support member configured and dimensioned to provide support to at least the motor.
11. An assembly according to claim 10 , wherein the rear housing includes a pair of spaced apart bosses that cooperate with a pair of apertures defined on the support structure.
