"May 25" to forge ahead: the national light in the field of slurry pumps

In the national-level high-tech industrial development zone of Xiangyang City, Hubei Province, there is a company that is like a bright pearl shining in the sky of special industrial pump manufacturing. It is Xiangyang 525 Pump Industry Co., Ltd. Since its establishment in 1968, the May 25 Pump Industry has shouldered the mission of the rise of the national manufacturing industry and has embarked on a solid and glorious path in the field of slurry pump manufacturing.​

Start a business hard and start a journey

In the late 1960s, China's industry was in a climbing period where there was a lot of waste to be developed. Basic manufacturing capabilities were weak. Many key pump equipment related to industrial development had long relied on imports. Core technologies and equipment were subject to the dilemma of others, becoming a "stuck neck" problem that restricts domestic industrial upgrading. In this call of the times, the May 25 pump industry was born in response to the situation. As the strategic fulcrum of China North Industry Group in the field of special industrial pump manufacturing, it shoulders the important task of breaking technological monopoly and revitalizing the national equipment manufacturing industry.

At the time of its founding, the company was faced with the test of "poor family background and harsh conditions": there were only 20 acres of crude site, more than 80 employees, outdated production equipment and lack of technical information, and everything needed to start from scratch. However, with the firm belief of "building China's own good pump" and the tenacity of "daring to bite hard bones" fought hard day and night-they started to improve without advanced equipment, and learned by doing without technical experience. From manual polishing in a simple factory building to the preliminary construction of the production line, every step is soaked with the sweat of struggle.

After more than 50 years of wind and rain, the May 25 pump industry has achieved leapfrog development: it has expanded from a small workshop-like factory area of 20 acres to a modern industrial base covering an area of 750 acres; from a start-up team of more than 80 people, it has grown into a professional team composed of more than 800 employees; from a single and simple production process, it has been upgraded to an intelligent manufacturing system covering the entire process of material research and development, product development, casting, heat treatment, machining, inspection and testing. In today's factory area, advanced equipment such as CNC machining centers, green intelligent casting production lines, and high-precision testing equipment are operating in an orderly manner, providing solid hardware support for the high-quality production of each slurry pump, and also allowing the 525 pump industry to stand firmly at the top of the scale of the domestic slurry pump manufacturing field.

Technology attacks and breaks monopoly​

After its establishment, the May 25 Pump Industry was not satisfied with simple production and manufacturing, but turned its attention to the highland of technology research and development. At that time, foreign countries were much ahead of China in slurry pump manufacturing technology, especially in key materials and core design, and imposed a technical blockade on our country. In 1986, the May 25 pump industry ushered in an opportunity for a technological breakthrough. The company resolutely introduced French slurry pump design and manufacturing technology and smelting and casting technology for special steel materials. However, introducing technology is only the first step. The May 25 pump industry knows that only by mastering independent technology can we truly break foreign monopoly.​

With its persistent investment in technology research and development, the company has quickly become a pioneer in the domestic slurry pump industry in the research of duplex stainless steel materials, high-chromium and high-vanadium wear-resistant alloy materials and large-scale commercial applications. In the laboratory for research on duplex stainless steel materials, scientific researchers persisted day and night. After countless tests and failures, they finally overcame technical problems and realized the mature application of duplex stainless steel materials in slurry pump manufacturing. This achievement not only improves the performance of slurry pumps, but also allows the May 25 pump industry to emerge in the industry. Since then, relying on its profound accumulation in material research, the company has participated in the formulation of national standards for special steel materials, gained the right to speak in the industry, demonstrating the strength of China's national manufacturing industry in technological innovation.​

On the road of independent innovation, the May 25 pump industry has achieved remarkable results, successfully developing more than 20 series of special industrial pumps with more than 600 specifications. Among them, slurry pumps, as the core product, are constantly introducing new ones.​

For example, for special working conditions in different industries, the R & D team has designed a variety of targeted slurry pump products. In the phosphorus chemical industry, slurry pumps face the challenge of strong corrosive media. The wear-resistant and corrosion-resistant slurry pumps developed by Wuerwu Pump use special alloy materials and surface treatment processes to effectively extend the service life of the pumps. In the mining metallurgy industry, slurry pumps need to withstand high concentration and high hardness slurry erosion wear. Wuerwu Pump improves the wear resistance of slurry pumps by optimizing pump body structure and hydraulic design. These innovative products have met the personalized needs of customers in different industries, enabled the 525 Pump Industry to occupy a leading position in the domestic market share for a long time, and gradually developed into the largest slurry pump manufacturing enterprise in China.​

In recent years, the May 25 pump industry has made major breakthroughs in the field of high-end ceramic pumps. Its independently developed "Ultra-High Wear and Corrosion-Resistant Silicon Carbide Ceramic-Lined Slurry Pump" won the third prize for Scientific and Technological Progress by China Ordnance Industry Group Co., Ltd. This product breaks the long-term technical monopoly of European and American countries and solves the problems of short life and high maintenance costs of traditional metal slurry pumps under high corrosion and high abrasion conditions. Through innovative hydraulic design, core flow component structure, material and forming process, the pump efficiency and impact resistance of this series of products have been greatly improved. The life of flow components has reached 3 - 5 times that of metal pumps. It has been widely used in desulfurization and non-ferrous metals. Key industries such as mineral processing and hydrometallurgy have saved a lot of operating costs for related companies and promoted technological upgrading in the industry.​

Twelve minutes of service, full-cycle escort

While technology and production capacity continue to lead the industry, the May 25 Pump Industry has always regarded "May 25 is twelve points of service" as the core criterion throughout enterprise operations-to provide solid basic services, value-added services with characteristics, and quality guarantees. A more assured service system, achieve the service goal of "twelve points of satisfaction", build a full-cycle service system covering pre-sales, sales and after-sales, and allow professional services and high-quality products to form a "two-wheel drive".

During the pre-sales stage, a special service team composed of technical consultants and industry experts was established on the May 20th Five-Year Plan to go deep into customer production sites in different industries such as phosphorus chemical industry, mining metallurgy, thermal power flue gas desulfurization, and nuclear power, combining the characteristics of working conditions, medium attributes, and core elements such as production capacity needs to provide "one-on-one" customized solutions. From pump type selection, parameter optimization to installation layout planning, the team used twelve minutes of meticulous and repeated deductions and verification to ensure that the plan not only meets actual production needs, but also is efficient, energy-saving and economical, and avoids cost waste caused by customers due to improper selection.

In the mid-sales process, the service team follows up the production progress throughout the entire process, and regularly provides customers with information on key nodes such as raw material inspection, key process processing, and finished product testing, so that customers can "see and feel at ease." For large-scale and customized slurry pump products, the company will also dispatch technicians to guide the installation and debugging, hands-on training customer operators in basic maintenance skills, and get through the last mile from "product delivery to stable operation" with twelve points of professionalism.
