The inner rubber layer is made of smooth, wear-resistant synthetic rubber, offering low fluid resistance and high water delivery efficiency. The middle layer is a high-tensile steel wire spiral reinforcement layer, resistant to negative pressure (-0.9 bar) and tensile strength, preventing flattening and deformation. The outer rubber layer is resistant to aging, UV rays, and wear, making it suitable for complex outdoor environments and extending its service life. The flexible suction and drainage hose has a robust structure, combining pressure resistance and flexibility, making it suitable for high-intensity operations.
With a small bending radius and excellent flexibility, the hose can be bent and coiled at will, easily bypassing obstacles, and is convenient to install and store. Its lightweight design makes it easy to move and can be operated by a single person, significantly improving construction efficiency. The flexible water absorption and drainage hose can adapt to narrow, rugged, and other special environments, offering flexible applications.
Made with a high-quality rubber compound, it has a temperature resistance range of -20℃ to 80℃, allowing for stable use in extreme temperature environments. It is resistant to aging, corrosion, and torsional fatigue, and can be dragged on sandy or muddy surfaces without easily breaking. This flexible absorbent and drain hose is suitable for municipal drainage, farmland flood control, river dredging, industrial water supply, and other applications, offering exceptional durability.
Inner diameter ranges from 25mm to 800mm, standard length is 20m/piece, and length, color, and connectors (flanges, quick couplings, unions, etc.) can be customized as needed; working pressure is 0.6-1.0MPa, burst pressure is ≥3 times the working pressure, ensuring a high safety factor. Flexible suction and drainage hoses can precisely match the needs of different equipment and working conditions.
Hengshui Zhehan Rubber & Plastic Co., Ltd. is deeply involved in the research and development and production of rubber and plastic products. With a complete quality management system, our flexible absorbent and drain hoses are manufactured in strict accordance with the HG/T 3035 standard. Each batch undergoes rigorous testing, ensuring reliable quality. We provide a one-year warranty and professional technical support, ensuring worry-free after-sales service.

Select a flexible suction and drainage hose with the appropriate inner diameter and pressure rating based on the conveying medium, flow rate, pressure, and suction lift requirements; ensure that the hose's working pressure is greater than or equal to the actual operating pressure, and that the suction lift does not exceed 8 meters to avoid overloading.
Clean both ends of the hose and the connector before connection to ensure there are no impurities or damage; - Use matching connectors for connection, and tighten the bolts evenly when connecting flanges to ensure a leak-free seal; - Avoid excessive twisting and scratches from sharp objects during installation, and ensure the bending radius is not less than 5 times the inner diameter of the hose; - Use hose clamps for reinforcement when fixing to avoid dragging and wear, and keep away from high-temperature heat sources and sharp edges.
Before starting, check the joint sealing and pipe integrity. Start the machine only if there are no abnormalities. - Avoid sudden pressure rises and falls during operation. Conduct regular inspections. If bulges, damage, or leaks are found, stop the machine immediately and replace the affected parts. - After the operation is completed, drain the medium from the pipe, clean the pipe, and coil it up and store it in a cool, dry place. Avoid exposure to sunlight, rain, and heavy pressure.
Do not exceed pressure or temperature: Flexible water absorption and drainage hoses must not be used beyond the rated pressure or temperature range. Avoid using mediums with excessively high temperatures or those containing strong acids, alkalis, or organic solvents, as this can lead to aging and corrosion of the hose.
Avoid mechanical damage: Do not drag, crush, or puncture with sharp objects during use. Keep away from welding sparks and high-temperature equipment to prevent damage to the outer adhesive and corrosion of the steel wire layer.
Storage guidelines: For long-term storage, keep the area clean and dry. The diameter of the coil should be ≥ 10 times the inner diameter of the tubing. Avoid folding and compression. The storage environment temperature should be -10℃ to 30℃, and the relative humidity should be 40%-70%. Keep away from chemicals and heat sources.
Regular replacement: It is recommended to use the hose every 1-2 years. Shorten the cycle if used frequently or in harsh environments. If signs of aging, cracking, bulging, or leakage appear, replace the flexible absorbent and drain hose immediately to eliminate safety hazards.
Professionally Adaptable: For special working conditions (high temperature, strong corrosion, large diameter), please contact the Hengshui Zhehan Rubber & Plastics technical team for a customized solution for flexible water absorption and drainage hoses, ensuring safe and efficient use.
