Ceramic sucker rod pump, our company's self-developed patented product, is a kindof new special oil extraction equipment in the petroleum drilling industry. Incomparison with traditional metal pump, there has been great improvement in thematerial and structure. By using unique technique, our company manufactures theceramic sucker rod pump by mounting the metal outside the ceramic. Thus the producthas the unique characteristics of high anti-wear ability, high anti-corrosionand high heat-resistance. Many years' trials in the Oil Extraction Company - asubsidiary of PetroChina Company Limited show that, compared with traditional metalpump, the cycle of check pump of the ceramic pump has prolonged for over twice,and the efficiency of pump has improved by 30%.In July 2006, the authority department of the country tested the ceramic sucker rodpump, and over 500 technical specifications have passed the test. In September,the Bureau of Science and Technology of Ningbo City held an appraisal meetingfor the ceramic sucker rod pump in Fenghua. Many technical authorities on suckerrod pump were invited; the experts participating in the meeting evaluated theproduct, and gave a high evaluation of our ceramic sucker rod pump. producing area:China
