Where does the purge unit on a centrifugal system take its suction from?

In a centrifugal system, the purge unit typically takes its suction from a point in the system where the fluid has the least amount of contaminants or undesirable elements, often from a separator or filter. This ensures that the purge process effectively removes impurities without introducing additional contaminants. The suction point is strategically chosen to maintain optimal system performance and prevent clogging or damage to the centrifugal pump.
