This exceptionally durable and thick-walled suction and transport hose is engineered for the most demanding applications, ensuring reliable performance in handling abrasive bulk materials such as granules, sand, gravel, pebbles, or agricultural substrates. Perfectly suited for loading and unloading silos, vehicles, suction excavators, or for transloading from tankers, it combines strength with flexibility, maintaining elasticity even at low temperatures. Its smooth interior guarantees efficient material flow, while the dense steel wire spiral reinforcement provides outstanding resistance to both pressure and vacuum, preventing collapse under heavy-duty conditions. With excellent abrasion resistance and additional resistance to oils and gasoline, the hose ensures long-lasting durability in industrial environments. Easy installation is possible with bridge clamps or specialized industrial fittings such as flanges, while custom diameters can be supplied on request. Available in two advanced versions: P3 SV PU, made of transparent polyester-polyurethane for maximum abrasion resistance, and P3 SV PU AE, crafted from polyether-polyurethane, offering resistance to microbes and hydrolysis, fully compliant with European and FDA regulations for temporary contact with dry, bulk, non-fatty foodstuffs. With a 2.5 mm wall thickness between spirals and an operating temperature range from -40°C to +100°C, this hose delivers uncompromising reliability, making it the ideal solution for industries seeking efficiency, safety, and superior performance in bulk material handling.
