PeristalticPumps&Tubing
The pumps presented on pages 92–108 require peristaltic tubing
to operate. Flow rate of a given fluid through a peristaltic tubing
pumpdependson two variables:
1. The speedof thepump,measured in revolutionsperminute (rpm)
2. Thevolumeheldwiththe internaldiameter (ID)oftheselectedtubing

1. Select the pump for your application from pages 92–104,
determinedby the requirementsof your fluiddelivery task(s):
a.
Level of accuracy
b. Fluid streams (#of channels)
c.
Flow rate range(s)
d. Need for constant flow, discretedispensing, or both
e.
Need for variable speed
f.
Need for automation/programmability
2.Note whether the selected pump requires 2-stop, 3-stop, or
standard tubing.
3. Review the tubingproperties tablesonpages62,70,75,and76and
select the tubingmaterial best suited for your application.
4. Reviewthepagethatcontains informationandoptions forthetubing
