    摘要: A turbine pump that permits an impeller to stay compliant with a raceway by the use of a preloaded floating raceway that operates by utilizing fluid floating on both side of the raceway within the pump. Exemplary embodiments of the pump include a mounting frame that is adapted to engage the pump to a drive source; an end frame that is adapted to attach to the mounting frame and includes an inlet section and an outlet section that facilitate fluid flow entering and exiting the pump; a motor shaft enclosed within the mounting frame; a floating raceway that is situated within the end frame and positioned around the distal end of the motor shaft, and includes an inlet passage, an outlet passage and a bypass hole fixed relative to the position of the inlet passage and the outlet passage; a spring located at the top of the floating raceway and at least partially contained within a corresponding cavity located in the end frame that is preloaded to help maintain a desired clearance between the floating raceway and the impeller; and an impeller secured to an distal end of the motor shaft.

    摘要: An assembly controls the liquid level in a vessel in which a submersible pump is disposed. The assembly has a switch housing and a float housing, arranged proximate to each other. A switch in the switch housing selectively energizes a motor associated with the pump. When a float disposed in the float housing moves in response to a change in the liquid level of the vessel, the movement is coupled to the switch by a pair of magnets arranged in attractive relationship to each other. One of the magnets is in the switch housing and the other is in the float housing. The magnets interact by providing force fields that acts through a wall that separates the switch housing and the float housing. A lever on which the switch housing magnet is positioned tilts the magnets away from alignment as they approach each other, reducing the increase in attractive force therebetween.
