Tubing Information

4-1

4.1 Selecting Tubing

Select a tubing material and size that is right for your

application (the fluid and flow rate that you are pumping).

Table 9-2 in Chapter 9, shows the average flow rates for

different size tubing. Normalized flow rates (mL per

revolution) vary significantly, based on motor speed, tubing

materials, viscosity, and mechanical tolerances in pump

dimensions. Table 9-3 outlines the variances resulting from

differences in motor speed, tubing materials, and mechanical

tolerances. Table 9-5 outlines the variances due to the

difference in viscosity.

To determine the chemical compatibility of a particular

tubing material, it is recommended that you test the tubing

under actual conditions.

Tubing materials that can be used include Vinyl, Viton,

Tygon, Silicone, Santoprene, and Norprene. Up to 68

durometer tubing can be used.

Poor tubing life results were obtained for

⁄16" (8.0mm)

inner diameter Santoprene tubing. This particular tubing

should not be used with the pump.

4.2 Tubing Life

Over time and high speeds, flow rates will drop as the tubing

wears out. Tubing life for various materials and sizes are

shown in Table 9-4 in Chapter 9. Tubing should be

periodically inspected for wear. Either move the tubing to a

fresh section, or replace tubing entirely (refer to Chapter 5).
