All materials, solid or liquid, have a small vapour pressure, and their outgassing becomes important when the vacuum pressure falls below this vapour pressure. Because of their mechanical limitations, such pumps can only achieve a low vacuum. A diaphragm pump (also known as a Membrane pump) is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable valves on either side of the diaphragm (check valve, butterfly valves, flap valves, or any other form of shut-off valves) to pump a fluid.. Pumps with factory-installed reservoirs are recommended when available. On an automatic transmission, a vacuum modulator leak will cause the engine to pull the transmission fluid into the combustion chamber, creating an abundance of smoke—along with transmission shifting problems. 140.
