* Metric mL per Revolution numbers are rounded off

Normalized flow rates (mL per revolution) vary significantly, based on

motor speed, tubing materials, and mechanical tolerances in pump

dimensions. In addition, the variances are different for the different

tubing dimensions. Variances from the normalized flow rates of Table

9-2 are shown below. The data is shown for new tubing only.

Tubing operating life tests are done at 600 RPM, with 20°C water, 0 PSI

back pressure until the tubing breaks
