Flux CombiFlux F 314 Electric & Battery Drum Pump Tubes

The Flux CombiFlux FP 314 sets the gold standard for portable, seal-less, battery drum pumps. It performs reliably in laboratories, production facilities, and mobile operations. Flux manufactures this modular battery drum pump in Germany and crafts it from polypropylene (PP), PVDF, or stainless steel 316 Ti. It enables safe, controlled transfer of corrosive and neutral liquids from small containers, 200-litre drums and 1000-litre IBCs.

Motor compatibility

Its compatibility with both the FBM-B 3100 brushless battery motor and the FEM 3070 electric motor makes the FP 314 exceptionally versatile. The pump features a seal-less design that removes the need for a mechanical seal. This reduces maintenance costs, extends service life, and improves dry-run capability. When paired with our brushless battery motor, the CombiFlux F 314 becomes fully mobile. This is ideal where trailing cables are unwanted or prohibited.
