Masterflex offers a wide range of pump tube formulations that can meet almost all applications. We choose and regulate
We tested each formula to ensure consistency and repeatability of performance. The allocation of applications should first be considered
Chemical compatibility, followed by temperature sensitivity.

Chemical compatibility
There are abundant resources available in our printed product catalog and, through our application experts,
We can help you choose the pump tube formula that is suitable for your application. The pump tube chemical compatibility chart is one of the resources.
These charts are derived from actual experimental data on peristaltic pumps.

We have also equipped a pump tube testing toolkit, which includes short pump tube samples of many of our available formulas.
You can and should use these samples for a simple immersion test in the fluid you are about to pump. unite
Immerse a small section of the pump tube in the fluid for a period of time, and then check if the sample size, color, weight, and strength are satisfactory
Make changes. Upon request, these test kits can be provided free of charge.

Temperature sensitivity
The friction generated by the movement of the roller on the pump tube is small, but it will produce measurable heat, which can affect
The mechanical properties of the pump tube may undergo minor changes in performance. Generally, Tygon ® Temperature of PVC based formula
The sensitivity of degree is the most obvious. Due to the need to reduce temperature sensitivity, it is recommended to use silicone gel as the formula for distribution applications
Viton ®、 PharMed ® And Norprene ®。

Sta-Pure ® Yes, it is one of the formulas for peristaltic pump tubing, which exhibits several characteristics that make it suitable for distribution
The ideal choice for use. Sta Pure has a very strong shape memory throughout the entire lifespan of the pump.
After a period of time, the deformation of its cross-sectional shape is very small. Therefore, the change in traffic is minimal. Sta Pure Excellence
A good shape memory is sufficient to eliminate the need for an initial break in period.

Size/flow range
Determine the size of the pump tube so that it is at or around the midpoint of the flow performance (in terms of flow rate per unit time) of the pump tube
Work. This can give you maximum flexibility to operate without approaching the upper or lower limit of the pump tube flow range
In this case, necessary process adjustments should be made.

Install the pump tube into the pump head
If you pay attention when installing the pump tube into the pump head, you can achieve * performance and * pumping life. When loading,
Be careful not to twist or twist the pump tube. Please note that the pump tube has a natural curvature. Place the pump tube through the roller or insert it
When biting on the bed, make full use of this curvature.

Pump tube running in period
After a few minutes of pumping, the flow stability of the peristaltic pump tube will show a significant increase. During this break in period,
Due to repeated compression of the rollers, the cross-section of the pump tube appears more elliptical. L/S ® The minimum break in period for the size pump tube is
15-20 minutes, I/P ® The pump tube takes 20-30 minutes.

Dimension and Tolerance
Masterflex drivers, pump heads, and pump tubing are designed collaboratively and require continuous monitoring and improvement to ensure
When used together in the entire pump system, it can provide * performance. The size and manufacturing tolerance of the pump tube are directly related
Affects the lifespan and distribution accuracy of pump tubes.

The flow rate of the pump tube with a specified size is determined based on the volume pumped by the roller per revolution. The volume pumped per revolution and the inner diameter of the pump tube
Directly proportional. Even small changes in the inner diameter can have a significant impact on flow accuracy. The outer diameter of the pump tube can change
Causing the pump tube to not be properly held in the pump head, either due to excessive or insufficient biting. These issues can also be addressed
Affects accuracy and pump tube lifespan. Masterflex pump tubing is manufactured with strict tolerances and has undergone monitoring and testing
Verify these tolerances. In order to achieve maximum precision and repeatability with Masterflex pump drivers, I
We strongly recommend that you only use Masterflex pump tubing.
