SAFETY PRECAUTIONS ® ® CAUTION: Use only pre-formed MASTERFLEX PTFE tub- ing. Use of other tubing may result in premature or unknown failure modes. WARNINGS: Turn drive off before removing or installing tubing. Fin- gers or loose clothing could be caught in the rollers. Use recommended fittings only. -
Page 5: Introduction
INTRODUCTION The Model 77390-00 PTFE Tubing Pump, Figure 1, provides quick loading of the special PTFE tubing assemblies. The pump is designed to work with the MASTERFLEX 2mm ID PTFE Tubing Model 77390-50 and 4mm ID Model 77390-60 and provides a wide flow range when used with compatible ®... -
Page 6: Application Data
APPLICATION DATA The Model 77390-00 PTFE Tubing Pump is used to pump caustic and/or sterile liquids, particularly those liquids that are not compatible with other existing MASTERFLEX tubing materials. The use of PTFE tubing provides improved liquid compatibility and maintenance of liquid purity. The specially designed tubing assemblies provide for intermittent operation at pressures up to 100 psig. -

Page 11: Recommended Occlusion Setting
c. where higher pressure filters are used that do not have a built-in pressure relief system. 2. HIGH SYSTEM-generated back pressures. AN INJECTION CHECK/BACK PRESSURE VALVE should always be installed when pumping into a pressurized reservoir or line. This will prevent siphoning and/or backflow of liquid from a treated line in the event of tubing failure. -
Page 12: Optimized Occlusion Settings
Optimized Occlusion Settings Occlusion is reduced by rotating the Adjustment Knob counterclockwise. Some applications require adjustment of the occlusion setting to maximize tube life while others require adjustment to maintain flow rate when substan- tial system pressure exists. However, the recommended setting will meet the requirements of most applications, giving both good tube life and some pressure capabilities. -
