Introduction of peristaltic pump hose

Platinum vulcanization, peroxide process

Soft, slightly transparent, smooth inner wall, low protein adhesion, low protein penetration

Food, sanitary

Suitable for pharmaceutical and biological fields

Temperature resistance: -51~238℃

Hose characteristics

It has a certain degree of flexibility and can quickly return to its original state after bearing pressure.

Have a certain ability to withstand pressure

No leakage, good air tightness

Low adsorption, good temperature resistance, not easy to age

No swelling, corrosion resistance, low precipitation

Hose parameters

The main parameters of hose specifications are inner diameter and wall thickness, and different manufacturers have different expressions. Currently there are specification codes, such as: 13#, 16#, 25#, etc. Or use "inner diameter×outer diameter" to indicate, such as: 1×1, 2×1, 3×1. There is also the use of color to indicate that different color hoses are suitable for different liquids.

Hose material

Silicone rubber, rubber, industrial plastics, polymer synthetic materials, different materials have different properties and have different uses

Factors to pay attention to when choosing a hose

1. Chemical resistance and compatibility

Test method: Soak test, take a section of hose into the solution and soak for 48 hours. After taking it out, observe whether the hose is damaged such as discoloration, swelling, rupture, etc. If not, the hose is compatible with the solution and can be used

2. Under pressure

The application of peristaltic pumps is limited by the pressure-bearing performance of the hose. Once the maximum pressure of the hose is reached, the hose will expand, causing excessive wear or direct rupture of the hose

3. Temperature

Depending on the material of the hose, the temperature should be considered when using the hose. The temperature resistance of the silicone tube for peristaltic pump is -51--238℃

4. Specification and size

According to flow requirements, choose hoses with different inner diameters. The inner diameter of the hose determines the flow rate, and the wall thickness affects the ability of the hose to be compressed and rebound, and also has a great impact on the life of the hose

5. Certification standards

The hose used meets the hygiene requirements and needs to pass relevant certifications. Such as the United States Pharmacopoeia standard USP, the European Pharmacopoeia standard EP, the United States Food and Drug Administration standard FDA, the United States Department of Agriculture standard USDA, the National Sanitation Foundation standard NSF

6. The hose is flexible, elastic and lifespan

Applicable to the hose on the peristaltic pump, the Shore hardness is 40-80, and the life of the hose is different according to the material of the hose and the use environment.
