Diaphragm metering pumps use a specially designed flexible diaphragm to replace the piston and achieve reciprocating movement under the action of the driving mechanism to complete the suction - discharge process. Because of the isolation of the diaphragm，the isolation between the measured fluid and the drive lubrication mechanism is achieved. The high-tech structural design and the selection of new materials have greatly improved the service life of the diaphragm. Coupled with the excellent corrosion resistance of composite materials, the diaphragm metering pump has become the main pump in the application of fluid metering. In the family of diaphragm metering pumps, hydraulic driven diaphragm pumps use hydraulic oil to drive the diaphragm evenly, overcome the possible failure caused by the rupture of diaphragm in the single-diaphragm metering pump。AILIPU pump is equipped with a double diaphragm and pressure alarm sensor to realize automatic linkage protection when diaphragm is broken. The improvement of the measurement of the pump head with double diaphragm structure improves its safety and is suitable for the application of special sensitivity to safety protection.
As a kind of diaphragm metering pump, electromagnetic driving metering pump generates pulsating driving force with electromagnet, and saves the motor and gear transmission mechanism, making the system compact and compact, which is an important branch of low-pressure metering pump in small range.
Now, the precision metering pump technology is very mature. Its fluid metering conveying capacity is up to 0-16,000L/H, and the working pressure is up to 4,000bar. The working range covers all the requirements of industrial production
