NEXT GEN PUMP, 4" Inlet x 3" Outlet, John Blue SP-3450-BS

The CDS-John Blue Company SP-3450-BS is a self-priming centrifugal pump designed for efficient liquid transfer in agricultural and industrial applications. Featuring a 4-inch inlet and 3-inch outlet, this pump delivers a maximum capacity of 560 gallons per minute (GPM) and operates at a maximum pressure of 64 pounds per square inch (PSI). It is engineered to run at a maximum speed of 3,600 revolutions per minute (RPM) and requires a 19-horsepower engine for optimal performance. The pump's construction includes extra-thick cast walls for enhanced strength and durability, and it is equipped with a keyed shaft clamp to prevent shaft slippage during operation. Additionally, the double wet seal design allows the pump to run dry for extended periods without damaging the mechanical seal faces, and the closed impeller design minimizes thrust loading on the drive motor, extending its life. The keyed shaft clamp is standard on 3-inch BS gasoline engine pumps.
