                 Peristaltic pumps for liquid handling

Principle
                       Peristaltic pumps are displacement pumps. They can be used for many different
                       tasks. Any medium passing it does not contact the mechanical parts of the pump.
                       Media containing solids can be transferred as well as aggressive chemicals.
                       The main part consists of a tubing and a rotor which compresses the flexible tubing.
                       The circular movement of the rollers forces the liquid to flow forward and through
                       the tubing.


Key facts/features

                       • Fast transfer of any type of liquids which may also contain solids
                       • Easy servicing and maintenance
                       • Different throughputs, according to the specific needs
                       • No limitation in the number of pumps
                       • For the control of a peristaltic pump one digital output is needed
                       • Controlled by tiamo with “Digital out” command, time controlled
                       • Input pressure range from –0.2 until 1bar, max. 2m of vertical tubing length (vis-
                         cosity and density may reduce the max. possible length)


                       Three different versions are available, tubing is included
                       40 mL/min
                       Fits if small volumes of liquids have to be added. It is also used in the
                       ProcessLab VA due the small amounts of solution needed.

                       120 mL/min
                       Useful for dosing of for example sample, buffers or complexing agents.

                       320 mL/min
                       This version has a high transfer speed and is normally used for draining and rinsing
                       of the titration vessel.
                                     Application Bulletin                                   No. 297e

Applications

                • Draining and rinsing of the titration vessel
                • Sample transfer to the titration vessel for Dosino loop sampling
                • Sample transfer to the sample loop for loop sampling system
                • Dosing of auxiliary solutions, e.g. buffers or masking agents
                • Transport of solid-containing media or some aggressive chemicals


Service & maintenance
                Service and maintenance are easy. For any works on a pump the tubings have to be
                rinsed and emptied first.
                To open the peristaltic pump, unscrew the two screws which hold the front. Now
                the whole pump head can be taken off for disassembling.
                As a preventive maintenance measure it is recommended to exchange the tubings
                on a regular basis. A typical expected lifetime is appr. 3 months. Use cable ties to fix
                the tubing on the tubing adapter. Please note that different factors like the runtime
                or the chemicals transferred may influence the lifetime of the tubing.
                It is recommended to exchange the roller carrier every 6 months.
