Hose suction-delivery o extreme flexibility intended for conveying liquid products industry petrochemical, containing up to 60% compounds aromatic. appropriate for use in tankers automotive for transport oil drive, ethanol, gasoline, oils. Layer inner with black, smooth rubber Chemigum ® (NBR, resistance to oil: RMA class A). Reinforcement cord synthetic and two spirals with wire steel. Layer outer, deep corrugated, with black rubber synthetic Chemivic ® (NBR/PVC), resistant to action substances petrochemical, oils and greases and on abrasion. It has a copper wire ensuring electrical continuity between the hose ends – under a condition correct connection for ends. thanks to external corrugation, hose is extremely pliable, a for its bending needed is small force. its minimal radius bends, equal is diameter internal hose. external serrated reduces also resistance pulling hose po ground, a light The design facilitates operating a hose. Inner layer: black NBR rubber. Reinforcement: cord synthetic, spirals steel. Outer layer: black synthetic rubber Chemivic®. Working pressure: from 10 bar to 17 bar – depending on the diameter hose. Vacuum: 0.9 bar. Operating temperature: od -40°C up to +93°C.
