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.
