5000 Working Hours Brushless Diaphragm Pump

5000 Working Hours Brushless Diaphragm Pump

1. Production overview
7121 Sequence micro diaphragm pump is a new module that independently developed by
Keyto. Its main purpose is diaphragm reciprocating by motor operates. This series is broad used
in healthcare instruments, environmental protection tools, meters, chemistry machinery,
house electrical, laboratory instruments and other advanced area.
1.1 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 created one path poppets at enter
and output port, to obtain medium aspiration and dispensing.
Traits:
1) Offer pure liquid transport and gas aspirate environment.
2) Oilless, upkeep cost-free, prolonged lifetime
three) Tiny vibration, low noise
4) Good sealing, corrosion resistance
5) Simple to assemble.
