As the name implies, processing using a specially designed flexible diaphragm diaphragm type metering pump to replace the piston, realize the reciprocating motion under the action of a driving mechanism, a suction discharge process. Due to the isolation effect of the diaphragm, the structure realizes the isolation between the measured fluid and drive lubrication mechanism. The structural design of high-tech and new materials has greatly improved the service life of the diaphragm, and the composite materials with excellent corrosion resistance, diaphragm metering pump has become the main fluid metering pump applications.

Diaphragm metering pump in family members, the hydraulic driven diaphragm pump adopts the hydraulic oil evenly driven diaphragm, direct drive approach to overcome the mechanical stress of diaphragm pump excessive concentration of defects, enhance the membrane life and maximum working pressure at work in order to overcome the fault of the single diaphragm metering pump may occur due to membrane damage caused, some damaged diaphragm metering pump is equipped with sensors, to achieve automatic linkage diaphragm rupture protection; measurement with double membrane structure of the pump head to further improve its safety, suitable for the application of safety protection especially sensitive.

As a kind of diaphragm metering pump, electromagnetic drive metering pump generates pulsating driving force with electromagnet, saves the motor and transmission mechanism, makes the system compact and compact, and is an important branch of small range low pressure metering pump

Now, the precision metering pump technology has been very mature, its fluid metering transmission capacity of up to 0-1000001/h, the highest working pressure up to 4000bar, the scope of work covering all areas of industrial production requirements
