Notes:
1. The flows shown above were generated on an EASY-LOAD pump.
2. Average barometric pressure is 740 mm Hg.
3. Flows shown are nominal or averaged.
4. PTFE Tubing Pump is being run @ 400 rpm, which is above its recommended rpm range; this is for intermittent use
(10–15 minutes) only and will result in shorter tubing life. For continuous use, do not exceed 300 rpm. Reduce flows by 33%
for use at 300 rpm.
