This extremely lightweight and highly flexible suction and discharge hose is engineered for the safe and efficient transfer of a wide range of chemical substances. Manufactured from advanced thermoplastic vulcanizate (TPV), it combines the easy processability of polypropylene with the durability and resistance of vulcanized EPDM rubber, ensuring excellent performance in demanding environments. Its outstanding chemical resistance makes it suitable for handling acids such as hydrochloric and sulfuric, bases, salts, alcohols, glycols, ketones, and concentrated detergents, while its weather, aging, and abrasion resistance (ISO 4649:150 mm³) guarantee long service life even under intensive use. The hose’s low weight and small bending radius provide exceptional maneuverability, making it ideal for operations involving tankers, containers, and mobile applications. Reinforced with a polyester braid and galvanized steel spiral, it delivers reliable strength and stability under working pressures of 7 to 15 bar (depending on diameter) at +20°C, with a wide operating temperature range from -25°C to +80°C. For applications requiring maximum resistance, the special VACUPRESS SUPER CHEMI version (up to 63 mm) features an inner polyethylene (LLDPE) lining, enabling safe use with concentrated hydrochloric, sulfuric, and nitric acids, as well as aggressive herbicides and insecticides. This makes it a versatile and dependable solution for industries seeking efficiency, safety, and durability in chemical transfer operations.
