HEFEI SHEGNYA MOTOR&PUMPS CO.,LTD is a professional company engaged in the development, production, manufacturing, and product service of submersible motors and pumps; It is the birthplace and research and development manufacturing base of submersible electric pump technology, and has always been a professional in the safety, large-scale (large diameter, large flow), high voltage level, high power, high speed, and intelligence (online monitoring, fault self diagnosis) of submersible electric pumps in China. We are a comprehensive manufacturing enterprise specializing in the production of complete sets of submersible motors, submersible pumps, supporting electrical control products, and intelligent automation system equipment for pumping stations.

As a high-tech enterprise, the company has a research and development team composed of multiple experts and professional engineers at or above the provincial level, as well as a group of energetic young engineers, with strong independent research and development capabilities. We have accumulated rich experience in design, manufacturing, and operation services in the technology and manufacturing process of submersible motors and submersible pumps, forming a complete range of submersible pump series models with mature, stable, and reliable applications. The main areas of products and services include (1) dry stator submersible motors with a power range of 7.5kW-1200kW, and wet stator submersible (water filled, oil filled) motors with a power range of 55kW-1800kW. Independently developed optimization design and calculation program for electromagnetic computers of submersible motors; Full waterproof insulation technology for high-voltage motors; Temperature rise technology for submersible motors; Motor sealing and cable sealing anti leakage technology; Variable frequency control technology for submersible motors; Online monitoring of motor dynamic and static insulation (leakage current), intelligent protection and control technology, etc. (2) The QZ/QH axis/mixed flow submersible pump is mainly used as a low head, high flow pump product from the 350-1800 series axis (mixed flow) submersible electric pump, which is increasingly widely used in fields such as water conservancy and drainage, municipal water supply and drainage, dock lifting and precipitation, environmental protection and ecological governance. (3) The submersible through flow submersible pump QG can form a mobile pump station with a gate, greatly improving the comprehensive utilization rate of the pump station equipment. It has high mobility, can be turned in both directions, and has various uses such as drainage, drought resistance, and water regulation. It has a wide range of uses and is an environmentally friendly equipment. (4) The WQ series sewage submersible pump is used for urban water supply and drainage, industrial water supply and drainage in factories, urban water supply engineering, flood control and drainage, etc.

All employees of the company are former employees of Hefei Sanyi Electric Pump Co., Ltd. (Hefei Motor Factory). We have been engaged in the production, manufacturing, and maintenance of high and low voltage submersible motors and submersible pumps for a long time. Having rich practical experience. Many technical and production personnel have participated in the design and manufacturing of large and medium-sized submersible pumps, such as the Shanghai Chemical Industry Zone 1400ZDB-100 (500kW 10kV), Shenyang Hunnan New Area Construction Bureau 1400HDB-50A (560kW 10kV), Quanzhou Puxi Drainage Station 1400ZDB-70 (560kW 10kV), and Meizhou Dadi 1800ZDBX-130 large submersible pump with planetary gear reduction (800kW 10kV).

Since its establishment, on the basis of inheriting the technology of existing large submersible electric pumps, the company has further summarized, standardized, and improved the key technologies for long-term reliability of submersible electric pumps in all aspects, and has obtained excellent patents, effectively solving the reliability of long-term safe operation of large and medium-sized submersible electric pumps.

The company has successfully provided a series of submersible electric pumps produced by our company to multiple units, including Ansteel Group in Liaoning Province, Tanggu District Water Bureau in Tianjin City, Hongcheng Water Industry in Jiangxi Province, Chaohu City Urban Flood Control and Drainage Management Station in Anhui Province, Shanghai Drainage Company, and Ma'anshan Construction Committee in Anhui Province, and has received praise from users. The constructed submersible pump station performs well in flood prevention and drainage.

We adhere to the business philosophy of "creating high-quality products for mutual benefit and win-win cooperation". Relying on a good corporate reputation, reliable product quality, comprehensive after-sales service, pursuing excellent work attitude, keeping up with the market, and warmly serving users, we have won a good market reputation. The numerous products launched by the company in the market have received high praise from customers in terms of appearance and quality.
