3-inch suction & discharge rubber hose

Core Parameters & Structure Analysis

1. Key Specification Parameters

2. Structure & Material Details

• Hose Body Material: Made of wear-resistant EPDM/NBR rubber with a smooth bore for minimal flow resistance. Resistant to pH5-9 weak acids and alkalis, preventing media residue and enabling easy cleaning. Suitable for water, sewage, slurry, diluted chemicals, oils and other media. The rubber material has high flexibility and can be bent frequently without cracking.
• Reinforcement Structure: Features a high-elasticity galvanized steel wire spiral frame for uniform support and anti-collapse performance during suction. A synthetic fiber braided layer greatly enhances the tensile strength and pressure resistance of the hose body, stably withstanding 1.0MPa positive pressure and -0.08MPa vacuum, adapting to complex working conditions.
• Outer Cover: Thickened wear-resistant rubber outer layer provides UV, ozone, and aging resistance. It remains crack and stiff-free outdoors, with abrasion and impact resistance, capable of withstanding vehicle rolling and heavy dragging. It is suitable for harsh operating environments such as construction sites and farmlands, significantly extending the service life.

Core Product Competitiveness

• Dual Condition Adaptability: Integrated suction & discharge design resists bulging under positive pressure and collapse under vacuum. One hose serves two functions, eliminating the need for additional dedicated suction/discharge hoses, with outstanding cost-effectiveness.
• Heavy-Duty Wear Resistance: Wear-resistant rubber hose body + steel wire spiral reinforcement offers compression, stretch, and aging resistance. The rubber material is resistant to low and high temperatures, remaining flexible at -25℃ and stable at 85℃, suitable for year-round use and harsh working conditions.
• Flexible & Easy Installation: High-elasticity rubber material + optimal bend radius (≥300mm) enables tight bends without dead angles, adapting to confined spaces and complex layouts.Flange/camlock ends allow tool-free quick installation and removal, improving operation efficiency.
• Wide Compatibility: The inner tube tolerates weak acids, alkalis, sewage, slurry, oils and other media, with a wide temperature range of -25℃ to 85℃. It covers multiple fields such as agriculture, industry, and environmental protection, suitable for both home and commercial use, adapting to various transportation scenarios.

Applicable Industries & Scenarios

• Agriculture: Farm irrigation, fish pond water exchange, flood drainage, water & fertilizer delivery, and pump compatibility for efficient long-distance water transport. Wear resistance adapts to complex farmland environments.
• Industry: Factory sewage discharge, circulating water transfer, weak chemical suction, slurry/dust conveyance in chemical, metallurgical, and building materials sectors. Corrosion and wear resistance adapt to complex industrial working conditions.
• Environmental Protection: Wastewater treatment plant sludge transfer, rainwater drainage, emergency pumping, river dredging. It is resistant to pollution and wear, suitable for high-impurity media, ensuring safe and efficient transportation.
• Construction & Municipal: Job site water drainage, foundation dewatering, concrete auxiliary conveyance, fire emergency water supply, and compatibility with mobile pump trucks & emergency equipment. Flexible bending adapts to narrow construction site spaces.
• Residential & Commercial: Pool/SPA water exchange, garden irrigation, basement drainage, small pump station use—lightweight, easy to operate, flexible and durable, suitable for both home and commercial applications.
