Cement Transfer Hose
Product Overview
Our cement transfer hose is engineered for the demanding conditions of cement handling and transportation in industrial environments. Designed specifically for conveying dry cement powder, fly ash, and similar abrasive materials, this robust hose ensures reliable performance under high-pressure pneumatic transfer systems. Constructed with premium multi-layer reinforcements, including high-tensile textile cords and steel wire spirals, the cement transfer hose offers exceptional abrasion resistance on both the inner and outer surfaces.
The inner tube is made from SBR (styrene-butadiene rubber) or NR (natural rubber) compounds, formulated to withstand the erosive nature of cement particles while maintaining flexibility for easy installation and maneuverability. The outer cover is UV and ozone resistant, protecting against environmental degradation in outdoor applications such as cement silos, batching plants, and truck loading stations. Available in standard lengths up to 20 meters and customizable diameters from 2" to 8", our cement transfer hose meets international standards like DIN 53516 and ISO 8033 for abrasion and adhesion testing.
Whether you're transferring cement from railcars to storage silos or feeding concrete mixers in construction sites, this hose minimizes downtime and reduces maintenance costs. Its static-dissipative properties also ensure safe operation by preventing spark generation in explosive atmospheres, making it ideal for compliance with ATEX directives in Europe and similar global safety regulations.
Key Features

Application Scenarios
The cement transfer hose excels in a variety of industrial settings where efficient and safe powder transfer is critical. In cement manufacturing plants, it facilitates the pneumatic conveyance of raw cement from silos to packaging lines or railcar unloaders, handling high-velocity flows without material degradation. Construction batching plants rely on it for loading cement into mixers from bulk trucks, ensuring dust-tight connections that comply with environmental regulations.
For ship and barge unloading operations at ports, the hose's abrasion resistance and flexibility allow for extended reach and articulation around complex geometries. In ready-mix concrete facilities, it supports high-volume transfers under variable pressures, minimizing blockages from fine cement particles. Additionally, mining and quarry sites use it for fly ash and cement dust relocation, while dry bulk terminals benefit from its durability in 24/7 operations. Its versatility extends to temporary setups like road repairs or infrastructure projects, where quick deployment and portability are essential.

FAQ
Q: What makes this cement transfer hose suitable for pneumatic systems?
A: Its reinforced construction handles high velocities and pressures up to 10 bar, with an inner tube designed for maximum abrasion resistance against cement particles.
Q: Can the hose be used for wet cement or slurries?
A: Primarily for dry powders; for slurries, consult our slurry hose range, as this model is optimized for dry pneumatic transfer.
Q: What end fittings are available?
A: Camlock, combination, Storz, PT, and flange types in aluminum, stainless steel, or malleable iron, crimped or swaged for secure seals.
Q: How do I maintain the cement transfer hose?
A: Inspect regularly for wear, avoid dragging on sharp surfaces, and store coiled away from direct sunlight. Clean with compressed air after use.
Q: Is it compliant with EU ATEX regulations?
A: Yes, the static-conductive version meets ATEX Zone 21/22 requirements for conductive hoses in potentially explosive atmospheres.
