This suction and delivery hose is built with an integrated rigid spiral steel wire skeleton and reinforced with multi-layer high-strength fiber wrapping, providing dual functionality for both negative pressure suction and positive pressure delivery. It will not collapse or deform during water suction or sewage discharge operations. The inner tube is made of water- and abrasion-resistant rubber that withstands the scouring of sand, mud, and sewage impurities, preventing scale accumulation and clogging. It is suitable for various media, including domestic sewage, industrial wastewater, and river slurry. The thickened outer cover is highly weather-resistant, offering excellent protection against dragging, tearing, UV rays, and ozone aging. It remains highly flexible even in low-temperature environments, making it easy to bend and route. It is widely used for liquid suction and discharge operations in municipal sewage treatment, construction site dewatering, aquaculture farm drainage, tanker water supply and drainage, and river dredging.
