Yixing Linggu Plastic Equipment Co., Ltd. (Yixing Engineering Plastic Equipment Factory) was founded in 1987. It is situated in Yixing city, which is the early manufacturer of engineering plastic pump. The company specializes in producing Linggu brand anti-corrosive and abrasion resistant engineering plastic pump manufactured with super high molecular weight polyethylene, and it firstly passed the state production license and ISO9001:2000 quality management system authentication. 
The company covers an area of 45,000 square meters, possesses 50 million Yuan of fixed assets, and has 150 million Yuan of production capacity. The company owns complete processing equipment, test equipment, and experimental facility, thus it is capable of developing, researching and testing various pumps. Metal workshop owns 45 sets of horizontal boring-mill processing center, three coordinate measuring system, dynamic balancer, vertical lathe, planer type milling machine, boring-milling machine, digital control wire-electrode cutting, common vehicle, milling, planning, drilling, grinding and other types of processing devices. The die-casting plant has 29 presses from 50 to 1,000 tons, 20 dryers in different specifications and 20 sets of auxiliary equipment. Assembly plant owns B level open test bed up to national standard, 2 sets of computer controlled detection systems, automatic data sampling, the maximum test flow can reach 4000m3/h. Every pump is inspected strictly according to GB3216 standard, and complete inspection report is offered. Besides, we have a set of special nozzle atomization testing system with latest patent technology, to test the atomization features with 5 atomization feature parametric curves. Our design and development center has strong technology force with 5 intermediate and senior engineers. We have the capability to independently design and develop kinds of products and mold. At present, the company has 1 invention patents, 12 utility model patents, and 5 seal patents. The center is equipped with physical and chemical analysis room that can do comparative analysis and test on materials. 
At present, the company has 17 series products: FUH series plastic horizontal pump, FDU series low revolving speed plastic pump, FTT silicon carbide pump, FLU series filter press pump, FCU side suction pump, FTU series ceramic composite pump, FYUB series cantilever submerged pump, FYUC series low revolving speed cantilever reject submerged pump, FZU series self-priming pump, IMC series magnetic driving pump, FRU series hose pump, FGU series pipeline, FQU series plastic pump, FXU series swirl slurry pump, FCF series lining plastic pump, FFU series float pump, FPZJ series water jet vacuum units in over 100 species and over 1000 specifications. The maximum flow is 4500m3/h, maximum pumping head is 80m, and under liquid work depth is 4m. We also produce supporting engineering plastic plastic-lined pipeline, pipe fitting, bottom valve, ball valve, diaphragm valve, compensator and nozzle. 
In addition, we have a mature customer service team and perfect customer service system, which can offer consultation, training, maintenance, guide and other services for customers. 
Now our products have been widely used in nonferrous metallurgy (gold, silver, copper, lead, zinc, nickel, cobalt, etc.), black metallurgy (steel scouring and manganese industry), titanium dioxide, petrochemical, phosphatic compound fertilizer, chemical fiber, citric acid, rare earth, environmental protection, power plant desulfurization, rare metal, medicine, pesticide and various industries to deliver sulfuric acid, phosphoric acid, hydrofluoric acid, fluosilicic acid, hydrochloric acid, mixed acid, electrolyte, gypsum slurry and various liquor or corrosive medium with solid particles. The products are well sold in 28 provinces, cities and municipalities and have been exported to Indonesia, Thailand, Vietnam, Malaysia, Mongolia, Brazil, Jordan, Iran, Africa, Taiwan, and other nations.
