The well is an internal pump component that forms a sealed chamber within the diaphragm pump assembly, providing the housing in which fluid pressure builds and is directed through the pump's discharge path. It works in conjunction with the diaphragm to maintain consistent volumetric flow and prevent internal leaks between the fluid and mechanical sides of the pump. When the well is cracked, worn, or improperly seated, the pump may lose prime, deliver inconsistent output, or allow fluid to migrate into areas of the pump that can cause accelerated wear to surrounding components.
