The Slurryflex DH-Series Self-Floating Hard-Wall Dredge Hose has an integral foam casing to allow it to float independently. It is suitable for suction and discharge duty.

This hard-wall hose consists of a slurry wear-resistant rubber inner layer, a wire helix reinforcement layer to contain internal pressure, and an outer cover that protects from UV, ozone, and external abrasion. This gives it greater flexibility and prevents kinking around bends or close to the dredge.

High-density closed cell foam provides buoyancy without the need for additional floats and also prevents water absorption. This avoids common problems such as catching or bunching which can cause the floating pipeline to sink.

Slurryflex hoses are completely custom made according to your specifications. We manufacture them in Australia from Slurryflex Grade A rubber for long-lasting resistance to abrasion, cutting, tearing, and overall wear. Talk to us about your application and we’ll help you choose the right hose for the job.
