New Appraisal Focus Serial 1-Mineral Metallurgy & Steel Mill


On December 17 of 2021, China Machinery Industry Federation and China General Machinery Industry Association jointly organized a national appraisal meeting of new products in CQPI office building. The four models of pumps independently developed by CQPI, high-temperature & high-pressure centrifugal hydrogenation feed pump, ultra-high pressure oilfield water injection pump, magnetic induction controlled hydraulic diaphragm pump, and ultra-high inlet pressure multistage centrifugal pump, finally passed the appraisal.


In view of breakthrough significance of application above in critical process area of iron and steel, mining and metallurgy, oil & gas and chemical, CQPI is scheduling to launch serial special reports based on appraisal and technical data to meet expectation of industrial end users.
