Processing Pump
The processing pump (see Figure 3-16) moves fluids into and out of the centrifuge bowl while
providing high flow rates with minimal hemolysis. In the autotransfusion protocols, the processing
pump can be operated at rates of 25 to 1,000 ml/min. in 25 ml/min. increments. In both the PPP and
PRP protocols, the pump can be operated at rates of 10 to 100 ml/min. in 10 ml/min. increments.

Processing Pump
The processing pump can be unfixed from its seat for cleaning purposes, as described in Chapter
15: Maintenance .
Air Detector
The air detector is located on the top console between the processing pump and the centrifuge bowl
(see Figure 3-17).
Figure 3-17 Location of the Air Detector
The air detector is an ultrasonic device that detects air in the tubing from the pump to the centrifuge
bowl. It is responsible for detecting the end point of the Empty phase and detecting when the
collection reservoir or wash bag becomes empty.
