Ceramic oil pumping is developed and produced to meet the needs of the oil mechanical equipment based on research achievement of the Seventh Five-year Plan. The application is the oil-fields, e.g. Dagang, North-China, Shengli and Jilin, showed that it can prominently improve the stability and efficiency of oil pumps, extending largely the cycle of checking, especially in aspects of corrosion-resistance, magnetic-resistance and wear-resistance (silt-ladenwells)
