Product Description
1. Production overview
71-CP Series micro diaphragm pump is a new module that independently developed by Keyto.
Its main function is diaphragm reciprocating by motor works. This series is wide used in medical
instruments, environmental protection equipment, meters, chemistry machinery, household
electrical, laboratory instruments and other advanced area.
1.1 Characteristics of 71-CP 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 designed single direction poppets at input and
output port, to achieve medium aspiration and dispensing.
Characteristics:
1) Offer pure liquid transport and gas aspirate environment.
2) Oilless, maintenance free, long lifetime;
3) Small vibration, low noise;
4) Good sealing, corrosion resistance;
5)Easy to assemble.
