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.

Soft suction hose, for larger diameters and small thicknesses almost flat at rest, intended for pneumatic transport of dry bulk materials. Inner layer made of black, smooth, antistatic rubber (R < 10⁶ Ω), abrasion-resistant (70±5 mm³ according to ISO 4649, formerly DIN 53516). Reinforcement with synthetic cord. Outer layer made of antistatic (R < 10⁶ Ω) abrasion-resistant rubber, weather-resistant and ozone-resistant. The hose is primarily used for the transfer of cement, sand, gravel, silica, and other dry abrasive materials from rail tankers, road tankers, and silos. Standard length: 60 m (or 120 m - contact Tubes International). Inner layer: black NR/SBR rubber. Reinforcement: synthetic cord. Outer layer: black NR/SBR rubber. Working pressure: from 5 bar to 6 bar - depending on the hose diameter. Operating temperature: from -40°C to +70°C. Indices marked at the end with the letters XE have an inner layer made of high-abrasion-resistant antistatic rubber (abrasion 50 mm³ according to ISO4649) and with a copper wire.

Pressure hose for pneumatic transport of dry abrasive substances. Special hose design with exceptional abrasion resistance. The inner layer is smooth, made of black antistatic natural rubber with embedded alumina (Al2O3) ceramic beads, a material with high hardness. Built-in copper wire that, when grounded (connected to a grounded end), dissipates electric charges. The outer layer is made of black antistatic (R<10⁶Ω) SBR/NR rubber resistant to abrasion and aging. The hose is intended for the transport of dry highly abrasive substances: e.g., dry cement, coal, coal dust, coke, solid fuels from secondary raw materials, minerals, ceramic powders, steel shot, glass shards, fiberglass. Used in steel mills, coking plants, power plants, cement plants, mines, glassworks, abrasive material factories, and insulation material factories. The advantage is the long lifespan of the hose in these applications – a traditional abrasion-resistant rubber hose may last only a few days, while the ALUSPHERE hose can last several months under the same conditions. Inner layer: ceramic beads embedded in black NR rubber. Reinforcement: synthetic cord. Outer layer: black SBR/NR rubber. Working pressure: 12 bar. Operating temperature: from -30°C to +80°C.
