Tubing Information

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.

NOTE

Poor tubing life results were obtained for 5⁄16" (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).
