Light and very flexible suction and discharge hose, designed for general industrial applications (in industry, construction, agriculture). It can be used for water, light chemicals, sludges and wastewater, plant protection products, other liquids (without fats, oils, and hydrocarbons) as well as for air, vacuum transport of dust, powders, granules, and other lightly abrasive bulk materials (non-greasy). Abrasiveness and potential static electricity issues should be considered. Reinforced with a hard PVC spiral, impact-resistant, providing good vacuum resistance and preventing hose collapse. The smooth inner surface reduces flow losses and ensures ease of cleaning. The outer surface is slightly corrugated, with smooth surfaces for small diameters. As a hose reinforced only with a hard PVC spiral, lacking a braid, it exhibits some elongation under pressure, which should be taken into account in applications, especially at elevated temperatures. Hose material: green transparent PVC. Reinforcement: hard PVC spiral. Working pressure at 20°C: from 2 bar to 6.5 bar – depending on the hose diameter. As the operating temperature increases, the working pressure value of the hose decreases. Operating temperature: from -25°C to +55°C.
