What Are the Effects of Peristaltic Pump Silicone Tube on Peristaltic Pump Performance?

The impact of peristaltic pump silicone tubing on peristaltic pump performance is mainly reflected in the following aspects:

  1. Tubing Material Characteristics:
  • Flexibility and Resilience:
    • The tubing needs to have good flexibility and resilience to quickly return to its original shape after being compressed.
    • If the tubing is too hard, it will increase the motor load and reduce the pump's lifespan.
  • Abrasion Resistance and Compression/Tear Resistance:
    • The tubing needs to withstand repeated compression and friction, so abrasion resistance and compression/tear resistance are crucial.
    • High-quality tubing can meet food hygiene and other relevant standards.
  • Air Tightness and Smooth Inner Wall:
    • Good air tightness can prevent leakage.
    • A smooth inner wall can reduce particle adhesion and prevent inner wall adhesion.
  • Other Characteristics:
    • Low adsorption, good temperature resistance, anti-aging, corrosion resistance, low extractables, and other characteristics also affect the performance and applicability of the tubing.
  1. Tubing Dimensions:
  • Inner Diameter:
    • The inner diameter determines the amount of fluid pumped per rotor revolution.
  • Wall Thickness:
    • Wall thickness affects the tubing's ability to return to its original shape after compression, thus affecting the pump's flow rate and lifespan.
  1. Tubing Lifespan:
  • In addition to the extrusion friction between the pump head and the hose, the compression method, compression force, number of compressions, and thermal fatigue wear caused by repeated use all have a great relationship with the service life of the peristaltic pump tube.
  • The running speed of the pump head, the material of the hose and the gap of the press tube between the pump head roller and the circular arc.

Summary:

Choosing the right peristaltic pump tubing is crucial for ensuring the performance of the peristaltic pump and extending its lifespan. It is necessary to comprehensively consider the material, size, and characteristics of the tubing to meet specific application needs.
