The history of TapfloTapflo was founded in Kungälv (north of Gothenburg), Sweden 1980 and has since then

been working with design and manufacture of air operated diaphragm pumps. The product rangehas grown from a few plasticmodels, to complete PE & PTFE,metal and sanitary series and lately alsowith complete ranges of centrifugal pumps.

Non-metallic pumpsThe wetted components are non-metallic injectionmoulded thermoplastics enabling excellent corrosion re-sistance. The version in PP-GF (glass fibre reinforced

polypropylene) provides great mechanical strength andallows liquid temperatures up to 70°C. The PVDF (Poly-Vinylidine DiFluoride) version has the superior chemi-cal resistance and allows temperatures up to 80°C.
