Centrifugal Pumps for Gasoline Engines

(Requires Base Mounting Plate for Engine)

Patented Vac-U-Seal impeller design creates a vacuum between the impeller and mechanical seal. Lack of pressure on the seal face minimizes seal wear and results in a longer seal life.
Double wet seal design provides for continuous lubrication of the seal faces. This wet seal design allows the pump to be run dry for extended periods with no damage to the mechanical seal faces.
Closed impeller design minimizes thrust loading on the drive motor extending the life of the drive motor. Impeller wear actually increases performance.
Extra thick cast walls provide extra strength and extend the life of the unit due to abrasion and corrosion.
Keyed Shaft Clamp (standard on the 3″ BS Pumps) prevents shaft slippage during operation.
