What Is Backpressure?
|
From Sensidyne, LP
When a pump is working to move air, it must overcome the forces that resist air movement. These forces include things like gravity and air density, internal pump/motor friction, resistance caused by the length and diameter of the tubing used and the resistance caused by any medium that the air is drawn through, such as filters or chemical sorbents. The sum total of all these forces is called backpressure, and it is a measure of how hard the pump has to work. Any time a pump is working, it is always working against some level of backpressure. In the case of personal monitoring pumps, some of these resistances are constant from sample to sample, such as the tubing size and the internal friction. But the component that can change significantly from one sample to another is the sample media, the resistance of which can be quite different from one media type to another type to another.

Plastic pumps are designed to move fluids that would corrode or damage other types of pumps. They provide broad chemical resistance and are less costly and lighter in weight than metal pumps.
