Slurry Suction Hose

Overview of Slurry Suction Hose

ZHW slurry suction hose can be made with a variety of high-grade tube material. 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 slurry suction 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.

Materials

Tube: NR, BR, SBR

Reinforcement: High tensile strength fabrics

Cover: NR, CR

Ideal working temperature: -20℃ to 80 ℃

Safety factor: 3:1

Application: Used for port, dock, discharge seawater, silt, flood, etc. Particularly suited to the work dredging construction for dock and port, Building Project, and soon.

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 slurry suction hose:
