Precautions to use a transparent PU duct hose
Peristaltic hoses are key components of peristaltic pump systems, designed to transfer water, oil, and other media. These hoses are specialized for use with peristaltic pumps and aren’t commonly found in other applications.
What Is a Peristaltic Hose?
A peristaltic pump hose is a positive-pressure-resistant hose with a unique structure. It consists of three layers:
Inner Rubber Tube
Made from composite rubbers like natural rubber, butyl rubber, or EPDM, this layer comes into direct contact with the pumped medium.
Skeleton Reinforcement Layer
Composed of high-strength polyester thread or steel wire, this layer provides structural support.
Outer Rubber Cover
Made from natural rubber, butyl rubber, EPDM, or similar materials, this layer protects the hose from external wear.
This design makes the hose soft, elastic, and highly wear-resistant. Synthetic fibers within the structure further enhance its strength, ensuring it can withstand repeated compression and relaxation during pump operation.
How It Works
Peristaltic hoses function with a rotor-driven positive-displacement mechanism. The pump’s rollers or shoes compress the hose, creating a “wave” that pushes media through the tube. This peristaltic action efficiently transfers gases, solids, and liquids, making it ideal for industrial applications.
Key benefits include:
Elasticity that maintains consistent flow.
Resistance to wear, pressure, corrosion, and aging.
