Abstract

A pump for use with a fluid circulation system for a recreational water body is disclosed. The pump includes a strainer housing, an impeller housing integrally formed with respect to the strainer housing, and an impeller cover mounted with respect to the impeller housing. The strainer housing includes a top portion having an outer surface adapted to engage with a strainer housing cover for mounting the strainer housing cover with respect to the strainer housing. A plurality of cams are formed circumferentially with respect to the outer surface of the top portion of the strainer housing. The cams are configured and dimensioned to cooperate with corresponding cam members formed with respect to an inner surface of the strainer housing cover. A positioning tab is formed with respect to the top portion of the strainer housing for appropriate alignment of the strainer housing cover. A positioning notch is formed with respect to the inner surface of the strainer housing cover. The notch cooperates with the tab to ensure proper strainer housing cover alignment. A stand is provided that defines a receiving chamber for receiving a securing feature that is mounted with respect to downwardly extending base portions associated with an impeller housing and an impeller cover.

Claims

1. A pump for use with a fluid circulation system, comprising:

(a) a strainer housing having an inner surface which defines a cavity for receiving a strainer;

(b) a housing cover adapted to be removably mounted with respect to the strainer housing for forming a seal with respect to the strainer housing, the housing cover including a pair of opposed handles;

(c) at least three ramped cam members formed with respect to an outer surface of the strainer housing, the cam members being adapted to correspond to cooperating cam members formed along an inner surface of the strainer housing cover; and

(d) at least three cooperating ramped cam members formed with respect to an inner surface of housing cover, the cooperating ramped cam members associated with the housing cover being configured and dimensioned for camming interaction with the ramped cam members associated with the strainer housing.

2. A pump according to claim 1, wherein the at least three cam members associated with the strainer housing are integrally formed with respect to an outer surface thereof.

3. A pump according to claim 1, wherein the at least three cam members associated with the strainer housing are circumferentially spaced and positioned substantially equidistant from one another.

4. A pump according to claim 1, wherein the strainer housing defines an upper rim and the housing cover defines a substantially U-shaped channel on an underside thereof said U-shaped channel being configured and dimensioned to receive said upper rim.

5. A pump according to claim 1, wherein at least one of the cam members associated with the housing cover defines a positioning notch and the strainer housing defines at least one positioning tab that is configured and dimensioned to interact with the positioning notch.

6. A pump according to claim 5, wherein the positioning notch and positioning tab are effective to align the pair of opposed handles in a desired orientation.

7. A pump according to claim 1, wherein the housing cover includes a frame and a lid mounted with respect to the frame.

8. A pump according to claim 7, wherein the lid is substantially transparent or translucent.

9. A pump according to claim 7, wherein the strainer housing defines an upper rim and the lid defines a substantially U-shaped channel on an underside thereof, said U-shaped channel being configured and dimensioned to receive and sealingly engage said upper rim.

10. A pump according to claim 1, wherein the strainer housing farther defines a circumferential ridge on an outer surface that contributes to interference engagement between the strainer housing and the housing cover.

11. A pump according to claim 1, further comprising a stand adapted to be removably mounted with respect to base portions of an impeller housing and an impeller cover.

12. A pump according to claim 11, wherein the stand includes a flange portion adapted to abut against the base portion of the impeller cover, the flange portion defining at least one receiving chamber adapted to receive at least one base securing feature for removably mounting the stand with respect to the base portion of the impeller cover.

13. A pump according to claim 12, wherein the at least one base securing feature passes through the base portions of the impeller housing and the impeller cover and engages the at least one receiving chamber defined with respect to the motor stand.

14. A pump according to claim 13, wherein the stand mounted with respect to the base portions of the impeller housing and the impeller cover provides structural support to the pump.

15. A pump for use with a fluid circulation system, comprising:

(a) a strainer housing having an inner surface which defines a cavity for receiving a strainer;

(b) an inlet formed on a front side of the strainer housing adapted to allow fluid to enter the strainer housing; and

(c) a housing cover adapted to be removably mounted with respect to the strainer housing for forming a seal with respect to the strainer housing, the housing cover having a pair of diametrically opposed handles extending radially with respect to the cover;

wherein a top portion of the strainer housing defines an opening adapted to allow access to the cavity defined by the inner surface of the strainer housing, the top portion having an outer surface adapted to cooperate with the strainer housing cover;

wherein a plurality of cam members are integrally formed with respect to the outer surface of the top portion of the strainer housing, the cam members being adapted to correspond to cooperating cam members formed along an inner surface of the strainer housing cover;

wherein a positioning tab is integrally formed with respect to the outer surface of the top portion of the strainer housing, the positioning tab corresponding to a positioning notch formed with respect to the inner surface of the strainer housing cover.

16. A pump according to claim 15, wherein the outer surface of the top portion of the strainer housing includes three cam members integrally formed with respect to the outer surface, and the housing cover includes three cooperating cam members corresponding to the cam members included on the outer surface of the top portion of the strainer housing.

17. A pump according to claim 16, wherein the cam members formed with respect to the outer surface of the top portion of the strainer housing protrude radially outwardly with respect to the outer surface of the top portion of the strainer housing and the cooperating cam members formed with respect to the inner surface of the strainer housing cover protrude radially inwardly with respect to the inner surface of the strainer housing cover.

18. A pump according to claim 15, further comprising a stand adapted to be removably mounted with respect to base portions of an impeller housing and an impeller cover.

19. A pump for use with a fluid circulation system, comprising:

(a) a strainer housing having an inner surface which defines a cavity for hosting a strainer;

(b) an inlet formed on a front side of the strainer housing adapted to allow fluid to enter the strainer housing;

(c) a strainer housing cover adapted to be removably mounted with respect to the strainer housing for forming a seal with respect to the strainer housing, the strainer housing cover having a pair of diametrically opposed handles extending radially with respect to the cover;

(d) a top portion of the strainer housing defining an opening adapted to allow access to the cavity defined by the inner surface of the strainer housing, the top portion having an outer surface adapted to cooperate with the strainer housing cover;

(e) a plurality of cam members integrally formed with respect to the outer surface of the top portion of the strainer housing, the cam members being adapted to correspond to cooperating cam members formed along an inner surface of the strainer housing cover;
