초록

A multi-diaphragm metering pump having first and second diaphragms mounted in a body in substantially parallel relationship, wherein an open fluid communication path is provided within the body between adjacent sides of the diaphragms and wherein each diaphragm forms a sealed wall within the body. A diaphragm stem connects the diaphragms, such that movement of the first diaphragm will cause movement of the second diaphragm substantially in unison. A source of pressurized fluid is intermittently injected into and exhausted from a remote side of the first ...
