Jiefang and Dongfeng have become the production bases for power steering pumps in the domestic automotive parts industry. On the basis of continuously improving power steering pumps for medium and heavy-duty vehicles, they have also taken the lead in developing VP series sedans and light vehicle power steering pumps in China. After years of development, a series of V10F, V10NF, V20F, V20NF, ZYB, DYB, VOP, VP and other automotive power steering pump products suitable for automotive power steering systems, providing pressure oil sources and determined flow rates for power steering systems, as well as a series of V10, V20 and other quantitative vane pump products suitable for various types of machine tools, hydraulic presses, injection molding machines, rolling mills and other fixed equipment hydraulic devices, have been formed. Since June 1992, they have been successively sold in FAW Jiefang Automobile, Dongfeng Automobile, Dachai, Xichai, CNHTC, Yuchai, Weichai, SAIC, Dandong Huanghai, Nanqi, Qingdao Automobile, Geely, etc. Foton, Tianjin Xiali, Hualing Motors, and Jianghuai Motors have successfully installed vehicles. In 1998, a cab overturning device was developed to support medium and heavy-duty trucks, which was supplied to units such as China National Heavy Duty Truck Corporation and BAIC Foton.
