This high-performance suction and pressure hose is engineered for the safe and efficient transfer of dry or liquid abrasive materials, granules, and other demanding media. Its externally corrugated yet internally smooth construction ensures optimal flow, while the transparent, abrasion-resistant polyurethane inner layer—ranging from 0.6 mm to 1 mm depending on diameter—guarantees durability even under intensive use. Reinforced with a rigid PVC spiral and integrated copper wire running along its length, the hose provides reliable discharge of static electricity when properly grounded, enhancing operational safety. The transparent PVC outer layer adds flexibility and resilience, making the hose resistant to punctures, cuts, and wear, particularly when handling sharp-edged plastic regenerates. Designed to meet the strict requirements of the food industry, it complies with European regulations 1935/2004/EC, 10/2011/EU, and 2023/2006/EC, making it suitable for contact with liquid food substances. With a working pressure range of 3 to 5 bar, vacuum resistance up to 0.7 bar, and an operating temperature span from -10°C to +60°C, this versatile hose is the ideal solution for industries seeking reliability, safety, and long-lasting performance in abrasive and food-grade applications.
