Established in 1965, located only 40 kilometers to the world-famous Three Gorges Project, Zhongnan Equipment Company Ltd. is a national large-scale industrial enterprise engaged in manufacturing subsurface pumps, sucker rods, drill collars, hydraulic cylinders, hydraulic hoists, electrical control panels, hydraulic control systems, precision photoelectric instruments such as infrared thermal image devices, periscopes, optical lenses and various hand tools, precision cold driven steel tubes and cold rolling tubs etc.

Our company covers an area of 500,000 square meters and has more than 2,000 workers and staff members, among whom are over 700 engineering technicians, 90 senior engineers and 10 country-level experts. We possess 2,000 various types of equipment, of which are 300 large-size and imported facilities with high, precision and sophisticated techniques. Moreover, we have shown outstanding technical superiority in precision optical instruments manufacturing and long-axis and deep-hole machining.

We have become a comprehensive enterprise manufacturing precision optical instruments, petroleum machinery and hydraulic machinery. Furthermore, we have passed the ISO9001 quality system certification and API Spec 11AX and API Spec 7-1.

Our photoelectric products include infrared image devices (both cooled and uncooled), periscopes for submarine, reconnaissance troops, boundary safeguards and other precision observation instruments, various lenses for cameras, video cameras, film projectors, duplicators lenses and reflectors, glass grating bars, stress meters and polarizer. Furthermore, our petroleum machinery consists of various rod pumps and tubing pumps with bore of dia. 26 to 130mm and max. length of 15m in accordance with API specifications such as RHA, RHB, RXB, RHT, RWA, RWB, RWT, TH, RSA, RSB, RST, TP and TLE. Some tools inside and outside wells such as logging tools and blow-out presenters. We can also supply various API drill collars and non magnetic drill collars. Our hydraulic machinery include punchers, spears, turbine governors, hydraulic units, electrical control panel (PLC), hydraulic hoists, hydraulic cylinders with bore dia. 32 to 1,100mm and stroke reaching 18mm. We can produce precision cold driven steel tubes and cold rolling tubes. In addition, we produce more than 1,000 other various hand tools such as oil ejectors, grease guns, pallet trucks, sleeves, spanners, wrenches, drills and socket sets.
