Oilless Maintenance Free Long Lifetime Diaphragm Pump

Oilless Maintenance Free Long Lifetime Diaphragm Pump

1. Production overview
7121 Series micro diaphragm pump is a new module that independently designed by
Keyto. Its major perform is diaphragm reciprocating by motor works. This series is vast used
in healthcare devices, environmental security gear, meters, chemistry equipment,
household electrical, laboratory devices and other sophisticated area.
one.one Qualities of 7121- series diaphragm pump:
The principal of diaphragm pump is the elastic diaphragm reciprocating by centrifugal
wheel
rotating, to change the quantity of chamber. And we created single path poppets at enter
and output port, to accomplish medium aspiration and dispensing.
Characteristics:
one) Supply pure liquid transport and gasoline aspirate environment.
2) Oilless, maintenance free, long life time
three) Small vibration, reduced sounds
four) Good sealing, corrosion resistance
5) Effortless to assemble.
