Product Description
7121 series diaphragm liquid pump is independently developed by Keyto. The main function is through the motor diaphragm reciprocating movement to achieve gas suction and discharge.
The principal of diaphragm pump is the elastic diaphragm reciprocating by centrifugal wheel rotating, to change the volume of chamber. And we designed single direction poppets at input and output port, to achieve medium aspiration and dispensing.
This series is widely used in medical equipment, environmental protection equipment, meters, chemical machinery, household appliances, laboratory instruments and other high-end applications.
