Chemical Dosing Metering Pump for sale As the name implies, the diaphragm metering pump use flexible diaphragm which is specially designed instead of the piston to complete reciprocating movement of inhalation-discharge process under the action of the driving mechanism. Because of the isolation function of the diaphragm, Diaphragm metering pump already achieved the real isolation in structure between the measured fluid and the driving lubrication mechanism. Diaphragm metering pump actually has become the main pump type in the fluid metering field, due to High-tech structural design technology and the new type materials use have greatly improved the service life of diaphragm, not to mention the excellent corrosion resistance performance of new type composite materials. Among the members of diaphragm metering pump family, hydraulic drive diaphragm pump overcomes the shortcoming of excessive concentration of force on diaphragm under mechanical direct drive mode by using hydraulic oil to drive diaphragm evenly, and improves the diaphragm life and working pressure upper limit. In order to overcome the possible working failure of single diaphragm metering pump caused by diaphragm breakage, some metering pumps are equipped with diaphragm breakage sensors to realize automatic interlocking protection when diaphragm breaks down; metering with double diaphragm structure pump head further improves its safety and is suitable for application occasions which are particularly sensitive to safety protection.
