The Diaphragm Pump of NEWDOSE can make the operation of it more safe and reliable by adding auxiliary valves and adopting double diaphragms with alarms. However, it has some disadvantages. The diaphragms of Diaphragm Pumps are easy to break, especially the fixed stroke diaphragm pumps. Once its diaphragms break, the metering fluid and the hydraulic oil system will pollute each other and cause damages, which will bring grave consequences. Let’s take a look at what is the structure principle of the Diaphragm Pumps.

Because of the isolating effect of the diaphragms, electric diaphragms pumps structurally achieves the actual isolation between the measured fluid and the drive lubrication mechanism. The high-tech structural design and the selection of new materials have greatly increased the service life of the diaphragm, coupled with the excellent corrosion resistance of PTFE (Teflon), Diaphragm Pumps now become the main type of pump in fluid metering applications.

1. Low cost

4. High tolerance of the PTFE diaphragms
