F/FP 430 Sealed Barrel Pump


Harco is proud to offer the FLUX F/FP 430 FOOD barrel pump, featuring a mechanical seal that works based on the principle of an axial-flow propeller pump. This efficient design includes a drive motor and pump unit. Via a clutch, the motor drives the drive shaft which has a propeller-like impellor attached to its end. Delivery by the pump requires that the impellor is completely covered with the fluid. The fluid is transferred axially due to the rotation, i.e., towards the pump discharge along the pump shaft.

In the FLUX F/FP 430 FOOD sealed barrel pump, the mechanical seal effectively isolates the inner tube from the fluid, preventing any fluid from getting into the inner tube. The shaft is exposed to the fluid only at the impeller, ensuring optimal performance.

Versatile and reliable, this universal FLUX F/FP 430 sealed barrel pump can be used for various media and is suitable for conveying fluids from drums, totes, IBCs and tanks. Designed for convenience, the pump can be quickly and easily disassembled into its two main components. Distinct feature, only at FLUX: The inner tube is reinforced with a metal core on plastic models (PP and PVDF). Ensuring the mechanical seal functions perfectly, this design prevents leaks and minimizes wear across the entire operating temperature range. Furthermore, it provides highest stability and makes immersion lengths of up to 118 in (3000 mm) possible.

For specialized applications, the stainless steel and Hastelloy C versions are certified for use in hazardous areas. Additionally, the stainless steel version is available with FOOD certification, ensuring it meets the highest standards for food safety.

Examples of media  – acids, alkalis, flavors and spirits. Models can be used in mobile and fixed installations.
