Chemical Barrel Pump – Flux F 424 Pump Kit for Acids & Alkalis

The Flux F 424 PP chemical barrel pump is a class-leading, seal-less pump. It safely and efficiently transfers aggressive acids, alkalis, and corrosive chemicals from 200–220 L drums and 1000 L IBCs. The F 424 PP features a heavy-duty polypropylene pump housing, a chemically resistant ETFE impeller and a reversible, high-strength Hastelloy C driveshaft. These components give the pump a class-leading service life while requiring minimal maintenance. The F 424 PP targets non-crystallising, low-viscosity fluids. It uses the unique Flux spiral PTFE shaft bearing system to enhance driveshaft support, reduce vibration and promote drainage. Furthermore, the absence of a mechanical seal in the fluid path allows the pump to dry run for limited periods, a significant factor in reducing repair and maintenance costs. The F 424 PP chemical barrel pump has been tested and approved by world-leading chemical manufacturers. Consequently, this pump is the ideal choice for chemical transfer in production, water treatment and laboratory applications.
