Additionally, the City of Camden was searching for metering pumps that were compact, accurate, and matched the specific features that they required. These pumps use compressed air as their power supply. The air behind diaphragm number two is being pushed out to the atmosphere causing atmospheric pressure diaphragm pump low flowrate vapor lock filetype pdf to push the liquid to the suction side.
