Micro-Diaphragm Gas-Sampling Pumps

Micro-Diaphragm Gas-Sampling Pumps

one. Production overview
7121 Sequence micro diaphragm pump is a new module that independently created by
Keyto. Its primary purpose is diaphragm reciprocating by motor performs. This series is extensive used
in health-related devices, environmental safety gear, meters, chemistry machinery,
family electrical, laboratory instruments and other advanced spot.
one.one Characteristics of 7121- series diaphragm pump:
The principal of diaphragm pump is the elastic diaphragm reciprocating by centrifugal
wheel
rotating, to change the volume of chamber. And we developed one path poppets at enter
and output port, to obtain medium aspiration and dispensing.
Traits:
1) Provide pure liquid transport and fuel aspirate surroundings.
two) Oilless, maintenance cost-free, prolonged life span
three) Modest vibration, reduced sound
4) Excellent sealing, corrosion resistance
5) Simple to assemble.
