Abstract
Examples of vacuum operated pumps are described herein. In an example, a vacuum operated pump includes a plurality of fluid ports, such as an inlet port and an outlet port. The vacuum operated pump may also include a communication port and a diaphragm. The communication port may provide for fluid communication among the plurality of fluid ports. The diaphragm may control the plurality of the fluid ports and the communication port. The diaphragm may mate with the communication port in an idle state of the vacuum operated pump to isolate each of the plurality of fluid ports.
