Our Factory
Since its establishment in 1998, Shijiazhuang Zhengrong Pump Industry Co., Ltd. has been operating from its corporate headquarters located at No. 41 Xingye Street in Shijiazhuang Economic and Technological Development Zone. The company's manufacturing operations are distributed across three specialized facilities: the main production plant, Zhengrong branch, and Qigong branch, which collectively occupy 198,000 square meters and maintain a combined annual production capacity of 10,000 tons. Each manufacturing facility operates self-sufficient production lines that encompass the complete manufacturing cycle from initial casting through final testing.
The company's core product portfolio consists of large marine dredging pumps, slurry pumps, and desulfurization pumps, supported by multiple proprietary patents. Its manufacturing infrastructure includes three sophisticated production lines featuring fully automated resin sand reclamation systems, patented American medium-frequency furnace technology, advanced heat treatment equipment, and a GS1000 vacuum direct-reading spectrometer from Germany's OBLF. Significant investment exceeding 50 million yuan has been allocated to enhance the large-scale dredge pump production capabilities.
To further strengthen its technological capabilities, the company has established strategic academic partnerships with several prestigious institutions, including Tsinghua University's Institute of Fluid Machinery and Engineering, Jiangsu University's Fluid Machinery Engineering Technology Research Center, and Hebei University of Science and Technology's School of Materials Science and Engineering. These collaborative relationships have yielded mutually beneficial outcomes and industry recognition.
