The flexible hose is the single wearing component of a peristaltic pump that makes direct contact with the pumped medium. Selecting the wrong elastomer can cause chemical degradation, rapid swelling, or thermal failures.

لاستیک طبیعی (Natural Rubber - NR)

-20°C to 80°C

Best For: Abrasive mining slurries, concrete mixes, abrasive drilling muds, tile glazes, and dense lime milk.
Description: Provides the highest mechanical fatigue resistance and flex life due to excellent elasticity. Exceptional resistance to particle abrasiveness but fails quickly when in contact with hydrocarbons, oils, or organic solvents.

اتیلن پروپیلن دی‌ان مونومر (EPDM)

-20°C to 90°C

Best For: Concentrated acids, strong alkalis, oxidizers, hot water, alcohols, and wastewater treatment dosing chemicals.
Description: Shows outstanding chemical resistance to a broad range of corrosive fluids. Should not be used for petroleum-based products, fuels, or hydrocarbon oils.

نیتریل بوتادین رابر (NBR / NBRF)

-20°C to 80°C

Best For: Fats, oils, grease, petroleum fluids, oily wastes, and food substances (specifically using NBRF food-grade).
Description: Highly resistant to animal fats, vegetable oils, and mineral lubricants. The NBRF food-grade variant complies with sanitary regulations for food processing.

سیلیکون (Silicone)

-20°C to 180°C

Best For: Sterile medical transfers, pharmaceuticals, biotechnology cell media dosing, and precision lab analysis.
Description: A highly flexible, translucent polymer that offers superb biological inertness. Can be repeatedly autoclaved but holds lower pressure limits compared to industrial reinforced rubbers.
