Description: This device consists of a metering pump, solution tank, a stirrer, a buffer, electrical control cabinet, an integral unit of pipes, valves and ancillary components are fixed on a common platform which consists of skid, the basic form of a pump jar, jar of two pumps, two cans three pumps, two four-pump tank, three cans of four pumps, two cans five pumps, three cans of five pumps, metering pumps and other four cans of six pump structure, in situ or remote manual and automatic control. It is widely used in the power plant of the raw water, boiler feed water, oil gathering and transportation dewatering system metering pump parts, petrochemical various dosing systems and wastewater treatment systems. As coagulant, phosphate, ammonia solution, lime, corrosion inhibitors, scale inhibitors, biocide agents. Check valve means relying on the flow of the medium itself automatically open and close the valve metering pump type, used to prevent media backflow valve, also known as non-return valve, check valve, reflux valve, and back pressure valve. Check valves are an automatic valve metering pump, its main role is to prevent the media back, to prevent the pump and drive motor reversal, and discharge the container medium. Check Valve (Check Valve): Nominal pressure or pressure level: PN1.0-16.0MPa, ANSI CLASS 150-900, JIS10-20K nominal diameter or caliber: DN15 ~ 900, NPS 1/4 ~ 36 Connection: France Portland, welding, threaded, socket weld, folders, and other applicable temperature: -196 ℃ ~ 540 ℃ Body Material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M ( 316L), Ti. Different material selection, check valves (aetv One-way valve): can be separately applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.
