The John Blue S-3320 is a 3-inch straight centrifugal pump designed for efficient liquid transfer in agricultural and industrial applications. Its patented Vac-U-Seal impeller design minimizes seal wear, extending the mechanical seal's lifespan. The double wet seal design allows for continuous lubrication, enabling the pump to run dry for extended periods without damaging the mechanical seal faces. The closed impeller design reduces thrust loading on the drive motor, enhancing its longevity, while the extra-thick cast walls provide additional strength and resistance to abrasion and corrosion. The S-3320 model features a 1-1/8-inch shaft and operates at a maximum speed of 3,600 rpm, delivering a maximum capacity of 365 gallons per minute and a maximum pressure of 60 psi at shut-off. It requires a 3-inch inlet and outlet and is compatible with a 10-horsepower engine. This pump is suitable for applications requiring high flow rates and durability, such as irrigation and chemical injection systems.
