Peristaltic Pump Tubings

The compatibility of a peristaltic pump with a certain type of fluid is almost completely dependent on the designof the tubing. This is why, when selecting a peristaltic pump, it is important not to overlook the selection of thepump tubing. Silicone tubing will normally give the highest dispensing accuracy. Most commonly used fordispensing applications silicone tubing meets USP and NFS Class VI standards.Food and medical quality and Autoclavable.

There are many factors that should be considered in this selection process.

Chemical compatibility the tubing material must be chemically compatible with the pumped fluid. Engineers should use a chemical compatibility chart designed specifically for pump tubing (not a general use chart) to aid in this decision.When a chart is not sufficient, immersion tests may be used to determine its compatibility or resistance to corrosion.
Pressure the tubing material must be able to withstand the system pressure without leakage or failure. It must also be able to adequately handle abrasive media and suspended solids.
Temperature the tubing material must be able to operate within the temperature range of the system. Users should identify the minimum and maximum temperatures reached in the system and select a material with an appropriate corresponding temperature range.
Size the tubing must be correctly sized in order to fit within the pump head and operate effectively. Closer dimensional tolerances will result in more consistent and repeatable performance.
Life expectancy the tubing material must have a tolerable rated life expectancy to reduce downtime and costs associated with replacement.
Transparency if the media needs to be viewed during pumping, the tubing material should be transparent
