Is the ULVAC® Hose for Conveying Sand, Grain, Pellets, and Cement suitable for both suction and pressure applications and safe with abrasive materials?

Yes. The ULVAC® Hose for Conveying Sand, Grain, Pellets, and Cement is designed for both suction and pressure service and is safe for abrasive materials. Its 3 mm smooth inner layer of wear‑resistant natural rubber and corrugated NR/SBR outer layer provide excellent abrasion resistance and mechanical durability. A steel spiral and synthetic cord reinforcement preserve flexibility, prevent kinking, and allow operation under high vacuum (up to 0.9 bar) and working pressures of 2–3 bar (depending on diameter). It functions reliably from −30°C to +70°C and includes a copper anti‑static wire to safely dissipate electrostatic charges in dusty or particle‑filled environments.

Can the ULVAC® Hose for Conveying Sand, Grain, Pellets, and Cement be used outdoors in extreme temperatures and resist UV and weathering?

Yes. The ULVAC® Hose for Conveying Sand, Grain, Pellets, and Cement can be used outdoors in extreme temperatures and resists UV and weathering. Its corrugated NR/SBR rubber outer layer provides excellent resistance to abrasion, harsh weather conditions and mechanical stress, while the hose remains fully functional across a wide temperature range of -30°C to +70°C. The construction (3 mm wear‑resistant inner rubber, synthetic cord reinforcement and steel spiral) ensures durability, flexibility and kink resistance for outdoor use. Additionally, the copper anti‑static wire adds safety by discharging electrostatic charges in dusty environments.

This highly durable and flexible rubber hose is engineered for efficient suction and transport of abrasive materials such as sand, gravel, cement, and residues from blasting operations, making it an essential solution for demanding industrial environments. Its smooth 3 mm thick inner layer, crafted from wear-resistant natural rubber in black or brown, ensures optimal flow and extended service life even under heavy-duty use. The corrugated outer layer, made of robust NR/SBR rubber, provides excellent resistance to abrasion, harsh weather conditions, and mechanical stress, guaranteeing reliable performance both indoors and outdoors. Reinforced with a strong synthetic cord and a steel spiral, the hose maintains outstanding flexibility while preventing kinking and withstanding high vacuum levels up to 0.9 bar. Designed for both suction and pressure applications, it operates safely within a working pressure range of 2 to 3 bar depending on diameter, and remains fully functional in extreme temperatures from -30°C to +70°C. For enhanced safety, it is equipped with a copper anti-static wire that effectively discharges electrostatic charges, ensuring secure operation in environments where dust and fine particles are present. This combination of strength, flexibility, and resistance makes the hose a reliable choice for industries requiring efficient handling of abrasive materials, offering long-lasting performance and reduced downtime.
