  • Pump with turbulence inducing tab
    Publication number: 20050265865
    Abstract: A centrifugal pump has a pump case and a rotatable impeller disposed within the pump case. A central aperture is defined within the rearward wall of the pump case to facilitate the connection of an impeller drive shaft to the impeller. A drive shaft seal is disposed within the central aperture to seal the impeller drive shaft to the pump case. A tab is disposed within the pump case such that it protrudes away from the rearward wall of the pump case. The tab is sized, dimensioned and located so as to create sufficient turbulence proximate to the drive shaft seal to suppress the buildup of heat and chemical precipitates around the drive shaft seal.

  • Pump with seal rinsing feature
    Patent number: 6966749
    Abstract: A centrifugal pump has a pump case and a rotatable impeller disposed within the pump case. A central aperture is defined within the rearward wall of the pump case to facilitate the connection of an impeller drive shaft to the impeller. A drive shaft seal is disposed within the central aperture to seal the impeller drive shaft to the pump case. At least one or more grooves are defined in the rearward wall of the pump case to carry liquids to and from the drive shaft seal. One or more radial ridges are disposed on the rearward side of the impeller to encourage liquids to flow within the grooves to and from the drive shaft seal to continuously wash away precipitates around the seal and to cool the seal.
