Is the VOLGA/BN SPECIALÂ® hose for sugar, grains, powders, granules safe for direct food contact and compliant with FDA 21 CFR 177.2600 and EU food regulations?

Yes. The VOLGA/BN SPECIALÂ® hose for sugar, grains, powders, granules is designed and specified for direct food contact and meets relevant food-contact regulations. The inner layer is a white, smooth, abrasionâresistant NR/SBR rubber formulated to comply with FDA 21 CFR 177.2600 requirements and is suitable for dry foodstuffs (sugar, grains, powders, feeds, granules). The product documentation also cites compliance with EU foodâcontact legislation 1935/2004/EC, GMP 2023/2006/EC, and BfR XXI category 4. The hose includes two builtâin copper wires for grounding to dissipate static, a nonâstaining white inner layer for sensitive materials, and is intended for pneumatic extraction/transport of dry abrasive and food substances. It is not intended for use in ATEX explosion hazard zones. Operating specs: working pressure 6â8 bar (depending on diameter), vacuum 0.9 bar, temperature range â30Â°C to +70Â°C. Standard lengths: 60 m (120 m on request).

Can the VOLGA/BN SPECIALÂ® hose for sugar, grains, powders, granules be grounded to prevent static buildup during pneumatic conveying?

Yes. The VOLGA/BN SPECIALÂ® hose for sugar, grains, powders, granules has two built-in copper wires designed to dissipate electric charges when grounded (or connected to a grounded end). Grounding these wires prevents static buildup during pneumatic conveying. Note: the hose is not intended for use in ATEX explosion-hazard zones, so ensure your applicationâs ignition-risk classification and grounding procedures meet applicable safety standards.

Does the VOLGA/BN SPECIALÂ® hose for sugar, grains, powders, granules resist abrasion from PVC granulate?

Yes. The VOLGA/BN SPECIALÂ® hose for sugar, grains, powders, granules is designed for dry abrasive substances and specifically lists PVC granulate among suitable media. Its inner layer is white, smooth, abrasionâresistant NR/SBR rubber (80 mmÂ³ by ISO 4649) compliant with FDA foodâcontact requirements and nonâstaining, making it appropriate for PVC granulate handling. The hose also includes two grounding copper wires to dissipate charge and an outer EPDM layer resistant to weather and ozone. It is not suitable for ATEX hazardous zones.
