Imperial Canned Pumps in the Nuclear Power Industry: Models

Dalian Imperial Shielded Pumps have a wide range of applications in the nuclear power industry, with its products covering almost all mainstream nuclear power plants in China, achieving a market share that once approached 90%. Addressing the extremely high requirements of nuclear power plants for safety, reliability, and special operating conditions, Imperial has developed several specialized models. Below are its core models, features, and application scenarios.

Model/Series Nuclear Safety Level/Features Typical Application Key Parameters/Remarks

ACP1000 Nuclear-Grade Shielded Pump Nuclear Grade III Exclusive supplier of nuclear grade III shielded pumps for the world's first "Hualong One" reactor (Fuqing Units 5 and 6). Single-suction, single-stage, horizontal, explosion-proof motor, noise ≤70dB, meets sealing requirements during extreme safety earthquakes (SL-2).

High-Temperature, High-Pressure Vertical Shielded Pump Nuclear Grade Special circuits requiring high temperature and pressure in nuclear power plants. Maximum design pressure 35MPa, maximum design temperature 400℃, maximum flow rate 1000m³/h.

Multi-stage (F-M type) Nuclear grade (applicable) Suitable for applications requiring high head, such as auxiliary feedwater systems in nuclear islands. Maximum head 800m, maximum flow rate 300m³/h, maximum power 220kW.

Borate recirculation pump Nuclear grade Used in the borate recirculation systems of units such as Yangjiang Nuclear Power Plant. Original equipment manufacturer (OEM) spare parts were still being procured in 2026, demonstrating its long-term stable operation. Model example: F72-416X4Z-0204U1V-HV.

💡 Core Applications and Market Position Extensive Application Performance: In addition to the models mentioned above, Dalian Imperial's canned pumps have served numerous key nuclear power projects in China, including Qinshan, Ling'ao, Ningde, Hongyanhe, Yangjiang, Fuqing, and Tianwan nuclear power plants. In 2025, CNNC Operation & Maintenance Technology Co., Ltd. continued to procure its circulation pumps, demonstrating its continuous supply capability in operating nuclear power plants.

Core Supplier for National Strategic Projects: As the exclusive supplier of the third-stage shielded pump for the first "Hualong One" nuclear reactor, Dalian Imperial played a crucial role in the export of domestically developed third-generation nuclear power technology. Its products are also widely used in aerospace and other fields with extremely high reliability requirements.

Rigorous Quality Control System: Imperial has held licenses for the design and manufacture of civilian nuclear pressure equipment since 1996. Although it was penalized in 2017 for operational violations, this also reflects the strictness of nuclear safety regulations.

🏭 Summary: Dalian Imperial's applications in the nuclear power industry can be summarized as follows: covering conventional high-lift requirements with multi-stage (F-M type) pumps; handling extreme circuits with high-temperature, high-pressure vertical models; supporting major national projects with ACP1000 nuclear-grade pumps; and providing long-term spare parts supply services throughout the entire lifecycle of existing units.

If you are interested in the technical details of a specific model (such as the ACP1000 pump used in the "Hualong One" reactor), or want to understand the selection criteria for a certain type of operating condition (such as boric acid circulation), we can continue to discuss this in more detail.
