Flowrox rubber diaphragms for tower press filters combine professional moulding manufacturing and benefits of more than 40 years of experience in elastomer technology and high stressed rubbers​. Each Flowrox diaphragm is fully moulded, made with one pressing, resulting in smooth transitions and high quality.

Improved functionality and extended lifetime

Besides professional moulding, Flowrox diaphragms have been improved based on valuable practical experience from the field and professional elastomer knowledge. The natural rubber (NR) compound is the most optimal for heavy duty filtration processes to endure immense pressures and have a longer lifetime. To make overall better diaphragms, several other improvements have been made. Diaphragm areas against pressing air outlet and feed inlet are now reinforced and therefore more durable. Grooves and pips secure free air outlet, improving diaphragm’s functionality.

Available sizes and materials of Flowrox diaphragms

Choose from diaphragms for 1,6 m² (flat and cupped), 2,5 m² and 6 m² tower press filter plate sizes. Four different rubber compounds are available: IIR, NR, NBR and EPDM. See datasheet for more information.
