Hunan Neptune Pump Co., Ltd. was founded in 2004. It is a "high-tech enterprise" and a "specialized and special new" small giant enterprise. It is one of the main backbone enterprises in China's pump industry. It is mainly engaged in the Design, R&D, production, sales and service  of industrial pumps and mobile emergency water supply and drainage equipment.

NEP (short for Hunan Neptune Pump Co., Ltd) has always adhered to technological innovation since its establishment, and has many innovation and technology platforms such as the "Permanent Magnet Motor Water Supply and Drainage Equipment Technology Research and Development Center", "Hunan Province Special Pump Engineering Technology Research Center", "Hunan Province Emergency Drainage Rescue Equipment Engineering Technology Research Center". It has obtained a total of 100 domestic patents (16 invention patents, 75 utility model patents, 9 design patents), and 15 software copyrights

(including wholly-owned subsidiaries); it is also the national machinery industry standard "Vertical Incline "Flow Pump", "Liquefied Natural Gas (LNG) Low-temperature Submersible Pump" standards, and the drafting unit of the national urban construction industry standard "Vertical Long Shaft Pump" standard. It is the drafting unit of the national building standard design atlas "Selection and Installation of Special Water Pumps for Fire Fighting" Participating companies.

NEP's industrial pump products mainly include vertical diagonal flow/long axis pumps, fire pump sets, split pumps and other pumps; mobile emergency water supply and drainage equipments mainly include large-flow portable drainage pump sets and mobile emergency water supply and drainage trucks. At present, the company's products have more than 5,000 specifications and models, which are widely used in industries or fields such as petrochemical, LNG, offshore platforms, steel, electric power, municipal water conservancy, emergency firefighting, flood control and drought relief. The vertical turbine pump/diagonal flow pump, fire (emergency) pump, and cryogenic pump series products are at the leading level of domestic technology. In particular, NEP's independently developed "vertical turbine dual-phase steel seawater pump" is the first in China's LNG receiving station to replaced imported products and has reached the international advanced level. It has been recognized as a "national key new product" and is widely used in many domestic LNG receiving stations.

NEP’s Methodologies about production and quality control are keeping improving and dedicated. It has built a complete quality assurance system and passed the ISO9001 quality management system, ISO14001 environmental management system, ISO45001 occupational health and safety management system, industrialization integration management system, weapons and equipment quality management system, CTEAS customers service system (seven-star) and product customers service certification and other system certifications. With NEP's high performance, NEP’s  products have passed product certifications such as EU CE, US FM, US UL, classification societies (BV and CCS), Russia and other five-nation alliances EAC certification, GOST certification and China Quality Certification Center. NEP has a large hydraulic testing center and uses CAD, PDM, CRM, and ERP to achieve effective system integration and improve the level of information management such as design, production, sales, and management.
