With the Drum pump F/FP 425 there is less than 0.05 l residual amount left in a 200 l drum, so maximum 0.02 %. The pump has an integrated backflow valve that is easy to close before taking the pump out of the container. Thus the backflow of the medium in the pump is prevented. This makes optimum use of especially expensive media possible and saves additional cleaning and disposal costs when handling problematic media. The pump is available in stainless steel, polypropylene and hastelloy C. In stainless steel and hastelloy C the pump F/FP 425 can also be used in hazardous areas.
