Overview of  Rubber Discharge Hose

ZHW  discharge hose can be made with a variety of high-grade tube materials.  These feature abrasion and cut-resistant premium grade rubber lining to withstand the destructive action of sand and gravel from quarries and beaches, rock and sludge from channels and harbors, coral from the sea.

In addition to the wire helix found close to the thick tube, multi-plies of polyester, nylon or cotton duck fabrics are used to reinforce the hose carcass to form an extra-heavy wall that absorbs shock and vibration between cutter head and pump. (These hoses can be custom-engineered to provide the bend radius you need.)

ZHW’s discharge hose is supplied with a number of cover choices, including SBR, EPDM or neoprene, to meet your most exacting need for wear resistance and protection from sunlight and ozone.

Structure

  1. The inner rubber liner is composed of wear-proof natural rubber and synthetic rubber
  2. The reinforcement layer is composed of high-strength rubber dipped chemical fiber and reinforced by spiral metal wire.
  3. The rubber cover is composed of natural rubber and synthetic rubber.
  4. The surface of the hose takes the shape of corrugated

Feature of ZHW rubber discharge hose:

  1. Design Concepts —- “No Leakage & No Bulge”
  2. Leak-Free Tube Lining Construction

・High oil resistant material

・Longer adhesion length

  1. Strong Flotation Construction

・No-Gas-Lock System

  1. Polyester Cord Reinforcement

・Better fatigue performance

・No permanent deformation (eg. Kinking)

・Non-Corrosion

・Light Weight

  1. Body Wire

Each helical wire in layer(s) is continuous without welding.
