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.
