1. Production overview
7121 Sequence micro diaphragm pump is a new module that independently created by
Keyto. Its major purpose is diaphragm reciprocating by motor performs. This series is extensive used
in healthcare instruments, environmental security products, meters, chemistry machinery,
family electrical, laboratory devices and other advanced region.
one.one Attributes of 7121- series diaphragm pump:
The principal of diaphragm pump is the elastic diaphragm reciprocating by centrifugal
wheel
rotating, to adjust the volume of chamber. And we designed single direction poppets at enter
and output port, to attain medium aspiration and dispensing.
Qualities:
one) Offer you pure liquid transportation and gas aspirate environment.
two) Oilless, routine maintenance free of charge, lengthy life span
3) Small vibration, minimal sound
4) Great sealing, corrosion resistance
five) Easy to assemble.
