Black Rubber Bulk Material S&D Hose with Steel Helix, Textile Plies and AS Wire

Description

The Mandrel Built Bulk Material Suction and Delivery Hose is engineered for the suction and delivery of abrasive materials like cement, chalk, lime, and fine abrasive powders. Designed for silos and tank trucks, it’s ideal for construction sites unloading cement, quarries handling lime, or industrial plants transferring powders, with a 3:1 safety ratio ensuring robust performance.

With a 10 Bar constant working pressure and 0.9 Bar constant vacuum across sizes from 51mm to 152mm inner diameters, this hose is certified for explosive environments (DEKRA report 16EXAM11132 BVS-bk, zones 0, 1, 2 per IEC/TS 60079-32-1:2016, TRGS 727:2016, EN ISO 8031:2010). Its conductive design (tube resistance 10³ to 10⁶ ohms, body wire <1 ohm/m when earthed) ensures safety in volatile settings.

Key Features:

• Abrasion-Resistant Tube: Black smooth conductive rubber, 50mm³ per ISO 4649.
• Reinforced: High tensile textile plies, steel wire helix, and antistatic wire.
• Durable Cover: Black smooth rubber, weather and abrasion resistant.
• Pressure & Vacuum: 10 Bar working pressure, 0.9 Bar vacuum across all sizes.
• Size Range: 51mm to 152mm ID with minimum 8mm wall thickness.
• Explosive Safety: Certified for zones 0, 1, 2 with conductive properties.

This hose is tailored for heavy-duty bulk material handling. The black conductive tube, with 50mm³ abrasion resistance, withstands cement or lime wear, while the antistatic wire and steel helix ensure safe suction in explosive environments like powder silos. Its minimum 8mm wall thickness supports durability for tank truck loading or unloading, and the smooth cover aids flexibility, making it a reliable choice for cement works, chemical plants, or chalk processing facilities.
