Products Description
Need a flexible, abrasion-resistant hose for demanding suction and material handling applications?
Guanjiang's PUR Suction Hose (Polyurethane Suction Hose) is an advanced industrial-grade flexible hose manufactured from high-performance polyurethane material. Specifically engineered for demanding suction and pneumatic conveying applications, it combines exceptional durability with remarkable flexibility. Featuring a smooth inner bore for optimal flow and reinforced with high-tensile steel wire to prevent collapse under vacuum, this hose offers 7-10 times better abrasion resistance than PVC — available in standard and anti-static versions.
Key Advantages
Outstanding wear resistance — 7-10 times more durable than PVC hoses. Maintains integrity when handling abrasive materials like wood chips, granules, and powders.
Excellent flexibility and kink resistance. High tensile strength with good elongation characteristics. Withstands repeated bending and flexing without damage.
Maintains flexibility from -40°C to +90°C (special grades up to 125°C). Resistant to oils, greases, and most chemicals — suitable for diverse industrial materials.
Anti-static versions for explosive environments (≤10⁶ Ω). ROHS compliant and environmentally friendly — transparent versions available for visual monitoring.
Smooth inner surface minimizes flow resistance and prevents material build-up — maximizes conveying efficiency.
Lightweight design reduces handling fatigue for operators — easier to maneuver in industrial environments.
Reinforced with high-tensile steel wire spiral — prevents collapse under vacuum conditions.

Frequently Asked Questions
Q1: How does PUR hose compare to PVC or rubber hose?
A: PUR (Polyurethane) offers 7-10x better abrasion resistance than PVC, remains flexible at low temperatures (-40°C), and resists oils and chemicals better than rubber. PVC becomes stiff in cold conditions and cracks over time. Rubber is heavier and less abrasion-resistant. For demanding material handling, PUR is the superior choice.
Q2: When should I use anti-static PUR hose?
A: Anti-static hose (≤10⁶ Ω surface resistance) is required for explosive environments where combustible dusts (wood, grain, chemicals, coal) or solvent vapors are present. It prevents static charge build-up that could cause sparking and ignition. Use anti-static for ATEX-classified areas or when handling flammable materials.
Q3: Is the hose suitable for food contact applications?
A: Yes. We offer food-grade PUR hose (FDA compliant) for food processing applications. The smooth inner bore prevents material buildup, and the material is non-toxic and odorless. Common applications include grain transfer, flour handling, sugar conveying, and ingredient dosing.
Q4: Can the hose be used for vacuum applications?
A: Yes. The steel wire spiral reinforcement prevents collapse under vacuum conditions. The hose maintains its round profile even under full vacuum (up to -0.09 MPa), ensuring consistent flow and preventing material blockages. Suitable for industrial vacuum systems and pneumatic conveying.
Q5: What is the maximum temperature rating?
A: Standard PUR hose operates from -40°C to +90°C. For high-temperature applications, we offer special grades rated up to 125°C. These are suitable for handling hot materials or use near heat sources. Please specify your temperature requirements when ordering.
