Product Description
Product Overview
7121 series micro diaphragm pump is a new module that independently developed by Keyto. The main function is through the motor diaphragm
reciprocating movement to achieve gas suction and discharge.
This series is wide used in medical equipment, environmental protection equipment, instrumentation, mechanical chemicals, household electrical, laboratory and other high-end fields.
Characteristics of of 7121 Series Diaphragm PumpThe 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 protection and corrosion resistance;
5)Easy to assemble.
