summary

The double head plunger metering pump is an improved metering pump model based on the ordinary plunger metering pump. The principle is also to directly suck in or discharge the working medium through the reciprocating movement of the plunger. Due to the use of a dual head design, the flow rate is twice that of a single head plunger metering pump under the same pressure. The pump head material has various grades of stainless steel to choose from, which has the advantages of simple structure, large flow rate, and high measurement accuracy. The plunger can be made of materials such as stainless steel, oxidized ceramics, and oxidized ceramics, which have the characteristics of corrosion resistance, high hardness, and wear resistance. The lateral active centering between the plunger and seal ensures minimal wear between the two. Because the pump head, plunger, and seal all directly touch the medium, selecting a composite pump head, plunger material, and seal form can ensure that the pump is more stable during operation. Widely used in wastewater treatment in the chemical industry, chemical additive addition in petrochemical boiler systems, additive addition in the production process of textile and paper industry, and quantitative injection of various chemical liquids in factories, laboratories, and other working conditions.
