Custom Dredger Hoses

For applications including hard wall suction and discharge hose, soft wall dishcarge hose in slurry pipe line, and specialty trunnion hose for suction cutter dredge. In addition to the high-wear-resistance rubber elastic inner liner, the ceramic tile inner liner can provide superior wear resistance.Expertly crafted to transfer of abrasive slurries, mineral processing.plants, tailings lines, sand and gravel. Other applications also available on engineering.

hard-wall-scution-discharge-hose

Features:

▪ Ideal for abrasive or slurry services

▪ Maintains a smooth, continuous interior bore

▪ Minimizes turbulence & prevents solid accumulation

Benefits:

▪ Prevents Clogging – Ideal for slurries and wastes

▪ Resists Abrasion – Smooth bore extends service life

▪ Controls Movement – for specific piping stresses
