Series EW · Suction & Delivery
Dredge Rubber Hose
Steel-cord reinforced rubber hoses for the harshest dredging duty.
Heartwork dredge rubber hoses are the workhorses of any suction cutter, TSHD or slurry line. Built with high-tensile steel wire helices, calendered NBR liners and abrasion-optimised covers, they carry silt, sand, gravel and mud at pressures other pipe simply cannot handle.
Key Features
Why field crews specify Heartwork
Vacuum resistant
Reinforced helix construction resists full-vacuum collapse on suction lines.
Sea-water safe
Cover compound engineered for salt-water, UV and ozone exposure.
Site-friendly
Choose flanged, open or bolt-on couplings — installed with standard tools.
Abrasion tuned
Liner formulated for the specific slurry — silt, sand, gravel or tailings.
Variants In This Line
Choose the configuration that fits your job
01
Suction Dredge Hose (Flanged)
For pump-suction service. Rigid flange ends for fast, leak-tight connection.
02
Suction Dredge Hose (Open End)
Field-fitted couplings for flexible layouts and quick maintenance.
03
Delivery Dredge Hose (Flanged)
Long-distance discharge lines pumping slurry and sand at high pressure.
04
Delivery Dredge Hose (Open End)
Temporary and short-run delivery lines that need to be reconfigured on site.
05
Floating Dredge Hose
Integrated buoyancy for open-water, deep-water and lake discharge.
06
Slurry / Mud Hose
Ultra-abrasion cover for mining, metallurgy and tailings service.
