The unique, patented MULTISAFE® technology with the hermetically sealed redundant double hose-diaphragms ensures double safety for transportation of critical and environmentally hazardous fluids. Two hose-diaphragms, arranged one inside the other, are fixed in the pump head. These hose-diaphragms enclose the medium ensuring double separation of the hydraulic drive end.
With the FELUWA hose diaphragm piston pump, the commonly utilised principle of a flat diaphragm has been extended by the additional provision of a flexible hose-diaphragm so that the conveyed fluid is in direct contact with the inside of the hose-diaphragm and check valves only.
FELUWA Pumpen GmbH received the order of a Russian refinery for the supply of a pump to process a slurry of Cobalt Carbonate particles and Isobutanol. The slurry has to be pumped with pressures up to 320 bar into a reactor within the process chain.
