7121 series micro diaphragm pump is a new module that is independently developed by Keyto. Its main function is to achieve liquid aspiration and dispensing by means of reciprocating movement of the diaphragm driven by motor. This 7121 series single-head micro diaphragm pump is widely used in medical instruments, environmental protection equipment, meters, chemistry machinery, household electrical, laboratory instruments, and other advanced areas.
