* 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
