Building Vacuum or Suck Liquid Diaphragm Pump

1. Creation overview
7121 Collection micro diaphragm pump is a new module that independently designed by
Keyto. Its principal operate is diaphragm reciprocating by motor works. This series is vast utilised
in healthcare devices, environmental defense tools, meters, chemistry equipment,
family electrical, laboratory devices and other superior area. Characteristics of 7121- collection diaphragm pump:
The principal of diaphragm pump is the elastic diaphragm reciprocating by centrifugal
rotating, to alter the volume of chamber. And we designed one direction poppets at input
and output port, to obtain medium aspiration and dispensing.
1) Supply pure liquid transportation and fuel aspirate surroundings.
2) Oilless, upkeep cost-free, extended lifetime
3) Tiny vibration, reduced sounds
four) Great sealing, corrosion resistance
5) Easy to assemble.
