Functional Design Theory
The Spectra Field Pro operates on mechanical peristalsis created through suction generated by a Pump
Head and Flexible Tubing. This allows for contactless fluid sampling in a variety of applications. The Field
Pro is limited by the ability to generate lift through vacuum and is only able to lift 27ft or 11m (at sea
level).
What is a Peristaltic Pump?
A peristaltic pump is a type of positive displacement pump used for pumping a variety of fluids.
Peristaltic pumps operate on a simple principle. The alternating pattern of squeezing and releasing the
tubing moves the fluid through the pump.
The fluid is contained within a flexible tube fitted inside a circular pump casing (though linear peristaltic
pumps have been made). A rotor with a number of 'rollers' attached to the external circumference
compresses the flexible tube.
As the roller moves faster, vacuum pockets are created more quickly and the fluid moving through the
system picks up speed. The rollers act as check valves to prevent siphoning or loss of prime.
