The two ebullating pumps P-104 and P-105, which were specially designed by our company for Fuhaichuang Petrochemical Co., Ltd. for a 1.5 million tons/year fluidized bed residue oil hydrogenation unit, have undergone one month of installation and commissioning, and finally achieved a successful one-time start-up! All performance indicators have met the design standards, earning high praise from the customers and laying a solid foundation for the future deepening of cooperation between both parties.   Strict Requirements for Core Equipment The ebullating pump is the "heart" of the 1.5 million tons/year fluidized bed residue oil hydrogenation unit and is a core equipment. The working conditions are high temperature, high pressure, with solid and gas content, which pose extremely high requirements for the stability and reliability of the circulating pump operation.           P-104 First-stage ebullating pump        P-105 Second-stage ebullating pump     Customized Research & Intensive Cultivation Since the project began, our technical team, relying on their profound research and development capabilities and rich experience, has carried out comprehensive customized design and precise manufacturing of the ebullating pump. From the selection of key components, structural optimization, to the simulation testing of the entire machine performance, every step strictly follows a quality control system higher than industry standards to ensure that the product can still maintain excellent performance under extreme conditions.         Motor performance test            Ebullating pump performance test     On-site Installation and Commissioning Successfully After the equipment was delivered to the customer's site, the professional service team of Huasheng Pumps & Valves responded promptly and immediately entered the site to work with the owner, the design team, and the construction team to complete the installation and commissioning of the equipment. During the installation and commissioning process, the service team, with their technical skills and rigorous attitude, precisely set and repeatedly checked the parameters of the equipment. After more than ten days of continuous efforts, the unit was finally successfully put into operation on January 9, 2026.            Ebullating pump hoisting    Ebullating pump installation  Dual frequency conversion debugging     Cultivate the Industry Deeply and Create the Future Together The successful one-time start-up of the ebullating pump in the 1.5 million tons/year fluidized bed residue oil hydrogenation unit is not only another powerful proof of Huasheng Pumps & Valves' technical strength and service level, but also a vivid manifestation of the company's continuous implementation of the development philosophy of "centering on customers and driven by innovation".      Looking ahead, Huasheng Pumps & Valves will remain committed to the petrochemical industry, with a strong focus on customer needs in specialized equipment, energy efficiency, environmental protection, and intelligent solutions.The company will continue to increase R&D investment, strengthen its independent innovation capabilities, and deliver equipment that is more efficient, more reliable, and more intelligent, working together with customers to promote sustainable industrial development.

Recently, the first high-flow, high-head submerged oil pump independently developed by Hefei Huasheng Pumps & Valves Co., Ltd. successfully completed full-load performance testing at the client's site, with all performance indicators meeting design requirements. This marks a significant breakthrough for the company in the field of deep-layer fluid transportation equipment. Figure——Overall scheme of the submerged oil pump independently developed by HSP     01. Leading Parameters for Demanding Conditions     The submerged oil pump is specifically designed for deep and demanding applications, with core parameters reaching the advanced level of the industry. Equipped with a high-power motor, it delivers large flow capacity and high head performance, capable of overcoming complex resistance conditions. It is ideal for large oil depots, energy development, and other high-end sectors, effectively addressing the challenges of traditional equipment such as insufficient flow, inadequate head, and poor adaptability to deep-layer operations.   02. Multiple Technical Advantages, Maximum Stability   Figure——Insulation resistance before pump start-up   From R&D and design to field commissioning, the pump has been developed with high stability and reliability as its core objectives.The newly developed conductive tube plug-in technology has undergone multiple rounds of testing and achieved “one-time successful connection” during both factory assembly and on-site installation, significantly improving assembly efficiency and sealing performance.   Before delivery, the equipment passed over 100 hours of intermittent testing and 72 hours of full-load continuous operation, with insulation resistance, DC electrical performance, and other key indicators meeting industry standards. On-site measurements showed that the three-phase DC resistance was well balanced, while the insulation resistance exceeded 200 MΩ, outperforming imported products and exceeding safety standards.   Figure —— DCS data of the submerged oil pump during operation     During full-load operation, the pump demonstrated outstanding performance: flow, head, and efficiency precisely matched the working conditions, with outlet pressure remaining stable and the motor’s three-phase current well balanced. The unit ran continuously for six hours without alarms, with oil temperature staying within the optimal range, and insulation resistance remained within standard limits even after shutdown—showcasing smooth startup, steady operation, and strong fault tolerance.     03. Independent Innovation Driving Industry Progress   The successful commissioning of this submerged oil pump marks another milestone in Hefei Huasheng Pumps & Valves’technological capabilities. It provides a replicable domestic solution for high-end submerged pump localization, helping customers reduce costs and enhance efficiency.   Looking ahead, Hefei Huasheng Pumps & Valves will continue to focus on technological innovation, further advancing the fluid handling industry and contributing to the high-quality development of the energy and chemical sectors.
