How to find the right Industrial Suction Hoses AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Industrial Suction Hoses
- Vacuum rating
- Choose a hose rated for full vacuum (about 29.9 inHg) for pump suction Hoses not rated for full vacuum flatten and starve the pump.
- Helix construction
- Use a rigid PVC helix for water and slurry, and a steel-wire helix for higher temperatures, solids and crush resistance The helix is what keeps a suction hose round under negative pressure.
- Bend radius under vacuum
- Respect the rated minimum bend radius, which is often larger under suction Bending a suction hose tighter than rated is the most common way to collapse it.
- Temperature
- Keep within the rated temperature range, and switch to rubber hose for hot service PVC suction hose stiffens in the cold and softens and loses vacuum rating in the heat.
- Couplings
- Match the hose ID to the pump inlet and use cam-lock or banded fittings rated for suction Air leaks at the coupling kill prime even when the hose itself is fine.
Brands that matter
- Kuriyama: Tigerflex PVC suction hoses are a common standard.
- Continental ContiTech: Rubber and PVC suction-and-discharge hoses.
- Novaflex: Heavy-duty suction hose for petroleum, chemical and material handling.
- Alfagomma: Industrial suction-and-discharge hoses.
What to avoid
- Using layflat discharge hose on the suction side
- Using worm-gear clamps on helix hose where banded or crimped couplings are specified
- Using PVC suction hose with hot water or oils it isn't rated for
