FP 424 Seal-less pump
Sealless in the liquid area
Seal-less pump F/FP 424 is ideal for transferring low-viscosity, aggressive or flammable liquids. It is suitable for free flowing, non-abrasive liquids that do not bond or crystallize. This pump is suitable for emptying drums, IBCs, tanks, vessels and basins. Flux F/FP 424 is the class leading heavy duty design, fitted with unique spiral-shaped guide bearing inside the inner tube. This provides superior driveshaft support, increasing service life, minimizing vibrations and preventing build-up of unwanted deposits in the pump. The pump is available in 316 stainless steel, polypropylene or polyvinylidene fluoride (PVDF) materials. The F/FP 424 in stainless steel is ATEX approved (to standard 2014/34/EU) for use in hazardous areas.
