400D1, 400DM2 and 400DM3 performance
Tube life and performance against pressure
The pressure and the suction heightcan be increased by compressing the spring in the sprung track pin. A
smaller gap between the rollers and track will give better performance against pressure but will reduce
tube life.
Other application factors that will influence tube life in peristaltic pumps are pump speed and number of
rollers (roller impacts/minute), temperature, chemical compatibility of the duty fluid and viscosity of the
duty fluid. Severaltubing materialsareavailable offering differentlevelsof lifeexpectancy.
Thetubing’sdimensionaltolerancesfrom themanufacturing processwillalso influence thelifeof a tube.
Thismeansthatitisimpossible to predicttube lifein any particular application.
In perfect conditions of no suction or discharge pressure, in a clean environment at normal room
temperature, and pumping water, nominaltube lifemay be:
Marprene and Bioprene: lessthan 6,000hours
Silicone: lessthan 250hours
Others: lessthan 100hours
Thefactorshighlighted above willtend to reduce tube life.
For precise and repeatable performance it
is important to determine flow rates under operating conditions for each new piece of
tubing.
Note: Flow rates quoted have been rounded for simplicity, but are accurate to within 5%—well within the
normal tubing tolerance variation of flow rate. They should therefore be taken as a guide. Real flow rates
in any application mustbedetermined empirically.
Note: The120S and the120U mustberun counterclockwise to achieve pressuresup to 2bar.
