Requirements for Peristaltic Pump Tubing and Its Differences from Ordinary Tubing

As we know, a peristaltic pump is a device used to transfer fluids, primarily consisting of a drive, pump head, and tubing. Among these components, tubing is a frequently used consumable. Some customers may consider using ordinary tubing as a substitute for specialized peristaltic pump tubing due to various reasons. However, this is not recommended. Below, we will elaborate on why peristaltic pumps require dedicated tubing.

Requirements for Peristaltic Pump Tubing

Peristaltic pumps demand high precision in fluid transfer. Thus, strict tolerances are imposed on the tubing's inner diameter. Peristaltic pump tubing exhibits excellent pressure resistance and corrosion resistance, offering significant advantages over ordinary tubing.

  1. Elasticity:The tubing must possess sufficient elasticity to quickly return to its original shape after being compressed.
  2. Abrasion Resistance:Given the inevitable presence of particles in the transported fluids, the tubing must exhibit high abrasion resistance.
  3. Pressure and Sealing Capabilities:Due to varying working environments and the pump's operating principle, the tubing must be able to withstand certain pressure levels and maintain a good seal.

Differences between Peristaltic Pump Tubing and Ordinary Tubing

  1. Deformation and Rebound:Since silicone tubing undergoes continuous compression during operation, it must be highly resistant to deformation and possess excellent rebound properties.
  2. Precision Dimensions:Peristaltic pumps require precise fluid transfer, demanding extremely accurate inner diameter and wall thickness dimensions for the silicone tubing. The inner diameter directly influences the flow rate of the pumped fluid, thereby affecting the pump's flow rate.
  3. Corrosion Resistance:Peristaltic pumps are used in a wide range of applications, including those involving acidic and alkaline solutions. Therefore, the tubing must exhibit superior corrosion resistance compared to other types of tubing.
