Development of high precision diaphragm metering pump

The hydraulic diaphragm metering pump is one of the most common and important units in the petroleum, chemical and water treatment projects. The development and production of the hydraulic diaphragm pump is a difficult problem. The utility model has the advantages of compact structure, less consumption, high efficiency, sanitation and environmental protection, etc.. At present, metering pump in domestic and foreign development has been more mature, but in the actual operation of the pump prone to export pressure and flow instability, easy to pump cavitation, inlet and outlet valve group and channel easy to plug and so on. Especially high-precision diaphragm metering pump in China is still blank, long-term foreign products occupied by the domestic market, and expensive, inconvenient maintenance. To this end, in 2003, China Petrochemical Corporation Maoming branch developed JMP high self suction diaphragm metering pump, the pump used in ethylene plant cracking workshop, the development of this research has important social and industrial significance.
