Product Description
Peristaltic pump silicone tubing is made of food-grade silicone material, manufactured using a platinum vulcanization process, resulting in uniform wall thickness and excellent elasticity. Its core transmission principle is that the peristaltic pump rotor compresses the tubing wall to create a vacuum, achieving purely physical transmission without valves or seals. This design avoids direct contact between the fluid and the pump body, structurally eliminating cross-contamination. Vertical extrusion molding ensures the accuracy of the hose dimensions, effectively controlling the flow stability of the peristaltic pump during operation. Different peristaltic pump hoses have varying resistance to repeated compression and friction from rollers; different hose types, materials, pump heads, and operating speeds result in different lifespans.

Performance characteristics of silicone tubing for peristaltic pumps
1. No corrosion or yellowing.
2. Possesses a certain degree of elasticity, meaning the tubing quickly recovers its shape after radial compression.
3. Has a certain degree of wear resistance.
4. Has a certain pressure resistance.
5. Leak-proof (good airtightness).
6. Long service life.
7. Low adsorption, good temperature resistance, not prone to aging, does not swell, is corrosion-resistant, and has low exudate content.
Applications of silicone tubing for peristaltic pumps
The advantage of silicone tubing in peristaltic pump operation is that all corrosive chemical fluids are transported solely through the tubing without contact with any other components of the pump. As long as the tubing remains intact, the peristaltic pump will maintain a clean and uncontaminated state.
FAQ
Q: 1. Why is silicone tubing suitable for peristaltic pumps?
A: Due to its excellent elasticity, fatigue resistance, and low compression set, silicone tubing can withstand repeated compression cycles without deformation or leakage.
Q: 2. What is the maximum temperature resistance of silicone peristaltic pump tubing?
A: Standard food-grade silicone tubing can withstand temperatures ≤200℃ for extended periods and 230℃ for short periods (<24 hours). Industrial-grade silicone tubing may have slightly lower temperature resistance due to additives.
Q: 3. What should I do if the silicone tubing of my peristaltic pump leaks?
A: Check if the tubing diameter matches the pump head (tolerances exceeding ±0.1mm may cause poor sealing); confirm the extrusion pressure is appropriate; if elasticity decreases due to aging, replace the tubing immediately.
Q: 4. What factors affect the service life of silicone pump tubing?
A: Temperature: Long-term exposure to temperatures above 200℃ will accelerate aging;
Media: Contact with hydrofluoric acid or high-temperature strong alkalis will shorten service life;
Usage Frequency: For high-frequency extrusion (>100 times/minute), it is recommended to select a fatigue-resistant model (such as Mastflex) to extend the replacement cycle.
Q: 5. Is this tubing resistant to corrosive chemicals?
A: Silicone tubing is suitable for various aqueous solutions and biological fluids, but is not recommended for use with strong acids, strong alkalis, or solvents. For these media, please use polytetrafluoroethylene (PTFE) or thermoplastic elastomer (TPE) tubing.
