FELUWA technology offers hermetically sealed pump systems for abrasive, aggressive and toxic media and various applications in the mining sector, like hydrotransport, ash disposal and dewatering. The FELUWA pumps are able to convey media with flow rates up to 1,000 m³/h and pressures up to 400 bar. A reliable overall diagnostic system for permanent condition monitoring is available.
MULTISAFE process pumps are of unique patented design and are especially conducive to the handling of aggressive and/or abrasive fluids and slurries. The redundant sealing of the product chamber from the hydraulic chamber is provided by means of two hose-diaphragms which are arranged one inside the other, although the pump only needs a single one to be fully functional. This new generation of diaphragm pumps is designed without the traditional flat diaphragm.
MULTISAFE pumps utilize an overall diagnostic system for permanent condition monitoring of primary and secondary hose-diaphragms (by means of pressure sensors), check valves (FELUWA Valve Performance Monitoring System – FVPMS), suction pressure as well as hydraulic and gearbox oil temperature.
FELUWA MULTISAFE positive displacement pumps in quintuplex design
FELUWA pumps are designed with relatively narrow cylindrically shaped pump heads when compared to standard diaphragm piston pumps and therefore allow for the arrangement of five single-acting plungers in parallel. When considering high flow and pressure rates, quintuplex design would not be economical for traditional diaphragm piston pumps because circular flat diaphragms would require a gearbox design that would be excessively wide to accommodate the size of the heads in parallel.
FELUWA MULTISAFE positive displacement pump, triplex design
Pumping of ore concentrate (copper, nickel, iron) at high solids concentration through pipelines is a profitable aternative to transportation by means of conveyor belts, rail or truck.
Hydraulic activated double hose-diaphragm pumps with downflow technology form FELUWA offer the best requirements because they are able to convey large solids with increased risk of sedimentation, allowing for a reliable transportation of critical bottom ash slurry over long distances.
