7122 series dual-head 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 7122 series dual-head micro diaphragm pump is widely used in medical instruments, environmental protection equipment, meters, chemistry machinery, household electrical, laboratory instruments, and other advanced areas.

1、The criterion of pumping vacuum is that the actual value larger than the standard value (e.g.-60Kpa).
2、If there are special technical requirements, please consult our engineers.
3、All flow and pressure are tested under standard atmospheric pressure.
4、Lead length of the brush-less motor is 300mm by default; the brush motor has no lead by default.
Note: Please kindly reach out to our sales team for design and specification final clarification and confirmation.
Offering pure working environment for liquid transfer and air aspiration and compression.
Oil-free, maintenance-free and long service life.
