DJ-W type mechanical diaphragm metering pump

Using the diaphragm type, economical, compact structure, the liquid end of the special engineering plastics manufacturing. Corrosion resistance and mechanical strength are excellent PVC, suitable for low-pressure occasions of precise measurement of fluids, with high metering accuracy and stability and higher use of supply and demand, diaphragm metering pump unique mechanical diaphragm design ensures that the flow rate of delivery and the proportion of the stroke between the linear relationship between the flow rate is practically not subject to changes in operating pressure.
