The sealless Drum pump F/FP 424 is ideal for transferring various low-viscosity and aggressive media. It is suitable for media that flows quickly and neither bond, crystallizes, or is abrasive. This pump can empty drums, IBCs and basins. The specific construction with a 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.
