Flux Drum Pump Sealless F 424 / FP 424

Flux Drum Pump Sealless F 424 / FP 424

FLUX drum and container pumps are always a "double act" comprising motor and pump. Both components can vary quite flexible. For example different pumps are able to be driven with the same motor. Ideal for reliable pumping of various low-viscosity liquids - incl. especially aggressive and highly flammable ones. As a result of their low weight the pumps can be easily carried from container to container. The easy handling of motor and pump keeps changeover times short.

The sealless Drum pump F/FP 424 is ideal for transferring various low-viscosity, also aggressive media. It is suitable for media that flow quickly and neither bond, crystallize nor are abrasive. With this pump you can empty drums, IBCs and also basins. Distinct feature, only at FLUX: The specific construction with spiral-shaped guide bearing in the inner tube prevents unwanted deposits in the pump and increases the service life significantly. The pump is available in stainless steel, polypropylene or polyvinylidene fluoride. The F/FP 424 in stainless steel can also be used in hazardous areas.
