Lightweight, highly flexible suction and discharge hose designed for water, juices, beverages, beer, wine, alcohols with a concentration of up to 20%, and other food products. Not recommended for milk and its derivatives, oils, and fatty food substances. Reinforced with a hard PVC spiral, impact-resistant, providing good resistance to vacuum and hose collapse. The transparent wall allows for easy visual monitoring of flow. The smooth inner surface reduces flow losses and ensures ease of cleaning. The outer surface is slightly corrugated. In applications not involving direct contact with food (in industry, construction, agriculture), it can be used: 1) for light chemicals, water, sludges, and wastewater, other liquids (without fats, oils, and hydrocarbons); 2) for air, vacuum transfer of dust, powders, granules, and other lightly abrasive bulk substances (non-fatty). Abrasiveness and potential static electricity issues should be considered. Standards and requirements: Food industry, contact with food: compliant with European regulations 1935/2004/EC and 10/2011/EU (simulant fluids A, B, and C), 2023/2006/EC (GMP). Hose material: transparent PVC. Reinforcement: hard PVC spiral. Working pressure: from 2 bar to 7 bar, depending on hose diameter. Operating temperature: from -10°C to +55°C.
