Double diaphragm pump 1 1/2'', plastic, PPB, PP/NBR, 370 l/min, 8 bar. Supplied = assembled. Connection type = 1 1/2 inch. Pump rate = 370 l/min. Operating pressure min./max. = 8 bar. Material of membrane = NBR. Seal material = NBR. For pumping solid particles with max. diameter = 7 mm. Pumping temperature = 60 C. For media = resins, pigment dyes. Material of pump = polypropylene (PP) Pumping height = 80 m wc. Max. viscosity at +20 C = 30000 mPas. Dry suction height = 4.5 m. Self-priming (even when dry) Maintenance-optimized design and easy installation. The double diaphragm pump is suitable for large-scale industry and plant loading as well as for high flow rates and higher viscosities Explanation of materials: EPDM = ethylene propylene diene rubber FPM = fluorine rubber NBR = acrylonitrile butadiene rubber PP = polypropylene PTFE = polytetrafluoroethylene TPC-ET = thermoplastic polyester elastomer TFM (PTFE) = modified polytetrafluoroethylene TPV (EPDM-PP) = EPDM/PP compound
