Light, flexible, hose suction-delivery o internal layer with resistant to abrasion and oil polyurethane, with densely arranged steel spiral reinforcing for increasing pressure working and resistance to vacuum. intended for air, liquids, light chemicals, in systems pneumatic, hydraulic and for conveying substances solid. smooth surface inner reduces losses flow and ensures ease cleaning. transparent wall allows on visual control of the flow. Reinforcement dense spiral with wire steel ensures very good resistance to vacuum and kinking hose and small radius bends. W use general-industrial It can be used: for water, light chemicals and other liquids based on fat, oils and hydrocarbons (should take into account resistance chemical polyurethane) and for air, for vacuum conveying dusts, powders, granulates and other abrasive substances bulk (should then take into account abrasion resistance medium and any problem electricity static). It can be used in industry food (tam, where acceptable are requirements American FDA 21 CFR 177.2600 e, f) for liquid substances food for food hydrated („e”) and greasy („f”). Inner layer: transparent polyurethane. Reinforcement: steel spiral. Outer layer: transparent PVC. Working pressure at a temperature of 20°C: from 12 bar to 20 bar – depending on the diameter hose. Operating temperature: from -20°C to +90°C. As the working temperature rises, the hose’s working pressure value decreases.
