ABSTRACT:
A vertical turbine pump is provided which includes a housing, a magnetic drive assembly attached to the housing, a vertical shaft assembly, an impeller assembly, and a thrust-compensating device. The vertical shaft assembly has an impeller-rotating section, a drive-interfacing section, and a transfer section therebetween. The impeller assembly is mounted to the impeller-rotating section of the shaft assembly and the housing includes a diffuser-bowl section which interfaces with the impeller assembly. The drive-interfacing section of the vertical shaft assembly is situated in a drive-interfacing position and rotational motion is magnetically conveyed from the magnetic drive assembly to the shaft assembly and thus to the impeller. The down-thrust compensating device compensates for down-thrust forces produced by the impeller assembly during rotation thereby maintaining the drive-interfacing end of the vertical shaft assembly in the drive-interfacing position and thereby maintaining the impeller assembly in proper position relative to the diffuser-bowl section of the housing.
