Very strong, thick suction-discharge hose designed for the transport of a wide range of wet and dry abrasive substances. The thick inner layer is smooth, antistatic, and abrasion-resistant (70 mm³ according to ISO 4649, formerly DIN 53516). Built-in copper wire that, when grounded (or connected to a grounded end), dissipates electric charges. The outer layer is corrugated, weather-resistant, and ozone-resistant. The hose is intended for the transport of abrasive substances mixed with water as well as dry materials: cement, sand, gravel, seeds, etc. Suitable for heavy-duty applications. It can be bent to a relatively small bending radius, but its deflection requires considerable force. It can also be easily cut into sections directly at the place of use and fitted with special PN10 flange fittings (applied to the outer surface of the hose). Used in many applications, e.g., for the transshipment of bulk materials in ports, for the transport of excavated material in mining, in the chemical industry, in construction during demolition work, for suction and transport of water and sludge in dewatering operations, in gravel and sand pits, in dredging and reclamation work. Installation: the hose is designed for installation using the VOLGA FRA system – aluminum half-flanges PN10 applied externally to the hose. Inner layer: black NR/SBR rubber. Reinforcement: synthetic cord, steel spiral. Outer layer: black EPDM rubber. Working pressure: 10 bar. Vacuum: 0.9 bar. Operating temperature: from -40°C to +70°C.

Suction and pressure hose for pneumatic transport of dry abrasive substances. Special hose construction with exceptional abrasion resistance. The inner layer is smooth, made of black antistatic natural rubber with embedded alumina (Al2O3) ceramic balls, a material with high hardness. Built-in copper wire that, when grounded (connected to a grounded end), dissipates electric charges. The outer layer is corrugated, made of black antistatic (R<10^6Ω) SBR/NR rubber resistant to abrasion and aging. The hose is designed for transporting dry highly abrasive substances: e.g., dry cement, coal, coke, solid fuels from secondary raw materials, minerals, ceramic powders, steel shot, glass shards, fiberglass. Used in steelworks, coking plants, power plants, cement plants, mines, glassworks, abrasive material factories, and insulation material factories. An advantage is the long lifespan of the hose in these applications; a traditional abrasion-resistant rubber hose may work for only a few days, while the ALUSPHERE hose can last several months under the same conditions. Installation: The hose is designed for installation using the GHIBLI system - aluminum half-flanges PN10 applied externally to the hose. Inner layer: ceramic balls embedded in black NR rubber. Reinforcement: synthetic cord, steel spiral. Outer layer: black SBR/NR rubber. Working pressure: from 8 bar to 10 bar - depending on the hose diameter. Vacuum: 0.9 bar. Operating temperature: from -30°C to +80°C.

Very lightweight and extremely flexible rubber hose for dust extraction, powders, and other lightly abrasive materials. The inner layer is smooth, made of wear-resistant rubber with a thickness of 2.4 mm. The outer layer is corrugated, resistant to abrasion and weather conditions. Thanks to the steel spiral reinforcement, it is resistant to kinking and vacuum up to 0.6 bar. Not intended for use with positive pressure, designed only for vacuum (extraction). Due to its lightness and exceptional flexibility for a rubber hose, it performs excellently in vacuum cleaning systems in the industry, such as in quarries or foundries. It features a copper anti-static wire for discharging electric charges. Inner layer: black natural rubber. Reinforcement: synthetic cord, steel spiral. Outer layer: black SBR rubber. Vacuum: up to 0.6 bar. Operating temperature: from -40°C to +70°C.
