Very lightweight, flexible suction and discharge hose designed for the transfer of chemical substances. Made from thermoplastic vulcanizate TPV – a material that combines the processing advantages of thermoplastic polymers (PP – polypropylene) with the properties of vulcanized rubber (EPDM). Good chemical resistance – similar to EPDM rubber allows for use with many substances, including acids (hydrochloric, sulfuric), bases, salts, alcohols, glycols, and ketones, concentrated detergents. Not recommended for fuels, oils, aromatic solvents. Resistant to weather conditions, aging, and abrasion (abrasion resistance according to ISO 4649:150 mm³). Low weight and small bending radius of the hose ensure ease of handling, which can be an advantage when transferring from tankers and containers. A special version, VACUPRESS SUPER CHEMI (diameters up to 63 mm), is available on special order with an inner layer lined with polyethylene (LLDPE), which increases the chemical resistance of the hose and allows its use with concentrated hydrochloric and sulfuric acids, nitric acid, as well as aggressive herbicides and insecticides. Inner layer: thermoplastic rubber TPV. Reinforcement: polyester braid, galvanized steel spiral. Outer layer: thermoplastic rubber TPV. Working pressure for temperature +20°C: from 7 to 15 bar – depending on the diameter of the hose. Operating temperature: from -25°C to +80°C.
