Diaphragm pumps work by moving two large diaphragms back and forth to move a fluid. Each diaphragm has two sides, a wet end and a dry end. The dry end fills with air first, expelling liquid from the wet end. Then, the air flows into the other diaphragm, and the wet end of the first diaphragm fills with fluid again.
