This exceptionally durable and thick-walled suction and transport hose is engineered for the most demanding applications involving abrasive bulk materials such as granules, grains, sand, or gravel. Its dense steel wire spiral reinforcement guarantees outstanding resistance to both pressure and vacuum, while the smooth inner surface ensures efficient material flow without clogging. The hose maintains elasticity even at very low temperatures, is non-compressible, and offers excellent resistance to abrasion, oils, and gasoline. Designed for secure installation with bridge clamps (right-handed) or industrial fittings such as flanges, it is available in multiple versions tailored to specific needs: **P3 S PU** – standard polyester-polyurethane with superior abrasion resistance; **P3 S PU AE** – polyether-polyurethane, resistant to microbes and hydrolysis, certified for temporary contact with dry, non-fatty foodstuffs in compliance with EU and FDA regulations; and **P3 S PU AS** – antistatic polyether-polyurethane (R ≤10⁸ Ω), compliant with TRBS 2153 and TRGS 727, ideal for safe suction in explosive atmospheres. With a wall thickness of 2 mm, transparent construction for easy flow control, and an operating temperature range from -40°C to +100°C, this hose combines strength, safety, and versatility, making it the perfect solution for industries requiring reliable performance in the transport of abrasive or sensitive materials.
