Large Diameter Water Suction and Discharge Hose

Combining suction and discharge capabilities, the JIDONGDA Large Diameter Water Suction and Discharge Hose is designed for transferring large volumes of water over long distances where high system reliability is essential. The use of integrated composite molding technology effectively eliminates the drawbacks typical of standard rubber hoses, such as vacuum collapse (deformation), poor abrasion resistance, and a short service life.

Backed by the modern facility's robust R&D and manufacturing capabilities, the Industrial Water Suction and Discharge Hose is suitable for handling various non-corrosive media, including fresh water, industrial process water, seawater, and lightly contaminated wastewater. It delivers reliable performance in harsh conditions, such as prolonged sun exposure, demanding mining operations, and intensive emergency water drainage tasks.

Product Construction

1 Inner Layer (Media-Contacting)

Made of high-quality synthetic rubber; this layer is water-resistant, abrasion-resistant, and offers moderate corrosion resistance. It does not crack or delaminate during prolonged contact with various types of water and is compatible with standard pumped media.

2 Steel Wire Spiral Reinforcement

A continuous high-strength steel wire spiral is integrated into the hose wall, forming a stable structural framework. This effectively prevents collapse or deformation during suction (vacuum operation), ensuring uninterrupted high-volume water intake.

3 Fiber Reinforcement Layer

A multi-layer cross-winding of high-strength polyester fiber around the hose significantly enhances its pressure resistance and tensile strength. The hose design allows it to withstand positive-pressure pumping as well as repeated bending and dragging without bulging or bursting.

4 Protective Outer Layer

A special weather-resistant rubber outer layer withstands UV radiation, precipitation-induced erosion, mechanical abrasion, and outdoor aging; it is suitable for long-term outdoor use, significantly extending the product's service life.

Key Product Features

1. Dual-function capability: suction and discharge

The hose is suitable for both suction (negative pressure) and discharge (positive pressure) operations; this eliminates the need to switch hoses and effectively reduces equipment setup costs.

2. High negative pressure resistance; deformation resistance

An internal steel wire reinforcement helix maintains the hose's circular shape during operation; it prevents the walls from compressing or collapsing under negative pressure, ensuring stable and continuous water flow.

3. Smooth inner surface; efficient transport

The optimized smooth inner wall design minimizes flow resistance and pressure loss, significantly enhancing water pumping efficiency and meeting the requirements of high-flow engineering projects.

4. Wear and weather resistance; high adaptability

The composite rubber material is resistant to aging and abrasion, allowing the hose to be used in harsh conditions—such as intense sunlight, friction against crushed rock at mining sites, and exposure to wastewater.

5. Flexible installation; extended service life

Excellent hose flexibility simplifies routing over complex terrain, ensuring quick and convenient installation. The use of high-quality raw materials and precision manufacturing results in a service life significantly longer than that of standard industrial hoses, leading to reduced maintenance costs.

Application Scenarios and Real-World Engineering Projects

1. Industrial Water Circulation Systems

Example: In 2025, a large manufacturing plant in East China selected JIDONGDA's specialized high-pressure suction and discharge hoses to upgrade its workshop cooling water circulation and equipment water supply systems. After more than 12 months of continuous operation, the hoses showed no signs of deformation, leakage, or aging-related damage; the upgrade improved coolant circulation efficiency and resolved issues with insufficient water supply.

2. Municipal Engineering and Emergency Water Drainage

Example: During a 2025 flood relief project in a city in South China, large-diameter suction and discharge hoses manufactured by JIDONGDA were used to pump accumulated water from roads and underground parking facilities. The product demonstrated excellent resistance to negative pressure, enabling rapid water removal from low-lying areas and effective operation under challenging installation conditions, thereby ensuring the success of flood control efforts.

Frequently Asked Questions

Q1: Can this Large Diameter Water Suction and Discharge Hose reliably withstand long-term operation in suction mode (under negative pressure)?

A1: Yes. The hose design includes a built-in continuous spiral of high-tensile steel wire that effectively resists negative pressure. The sleeve does not flatten, deform or become clogged during prolonged suction. Optimized for suction pumping, it provides consistent flow rates and outperforms standard rubber hoses.

Q2: What custom modifications does JIDONGDA offer for special operating conditions?

A2: We offer various models adapted to the type of pumped medium and operating conditions, including: seawater and corrosion resistant (for marine and port work), oil resistant (for fuel pumping), acid and alkali resistant (for the chemical industry), food and antistatic hoses. We can also change the diameter, length and operating pressure of the hose, and offer different connection options such as flanges or quick couplings.

Q3: What is the difference in service life between industrial hoses and standard household hoses?

A3: JIDONGDA hoses use industrial grade composite materials and professional production technology to ensure superior wear resistance, as well as weather and aging resistance. Under standard operating conditions, their service life is 3–5 times longer than that of conventional household hoses. They withstand long periods of outdoor exposure, mechanical friction and intense, continuous use, reducing long-term maintenance costs and ensuring high overall performance.
