Imperial canned  Pump Basic Model (F Series) Structural Parameters and Application Industries

The Dalian Imperial Shielded Pump Basic Model (F Series) is the core and most widely used cornerstone model in its product family. With absolute zero leakage as its primary goal, it is specifically designed for conveying clean, particulate-free, and non-vaporizing medium- and low-temperature media. While ensuring the highest safety standards, it also achieves a compact structure and quiet operation.

To provide a clearer understanding, I have summarized its structural features, key parameters, and core application industries as follows:

🔧 Structural Features: How is zero leakage achieved?

The F Series fundamentally eliminates the leakage risk of traditional pumps through ingenious integrated design. Its core structure can be summarized as follows:

Integrated Static Seal: The motor and pump body are integrated into one unit, and the impeller is directly mounted on the motor rotor shaft. The entire system has only a few static sealing points, completely eliminating the dynamic rotating shaft seal and preventing media leakage at its source.

**Shielding Sleeve Isolation:** The stator and rotor of the motor are sealed and welded with thin-walled, non-magnetic metal (shielding sleeves), completely isolating the motor windings and core from the conveyed medium. This prevents corrosion of the motor and contamination of the medium by the motor.

**Media Self-Lubrication and Cooling:** The entire rotor is immersed in the conveyed medium. During operation, a portion of the medium enters the motor cavity to lubricate and cool the two sliding bearings before circulating back to the pump inlet. This design eliminates the need for external lubricating oil but requires the medium to be clean and free of solid particles.

**Optional Internal Circulation Design (F-V/FA-V Type):** For applications with extremely high safety requirements, the basic model can also adopt an internal circulation structure. The circulating fluid returns directly to the impeller inlet through an internal channel, eliminating the need for external circulation pipes, further reducing potential leakage points, and making the structure more compact and safer to operate.

📊 Key Parameters: How Wide is the Coverage?

According to official data, the performance parameters of the basic model (F series) cover a wide range, meeting the needs of most conventional industries.

Parameter Range
Flow Rate: Maximum 1000 m³/h
Head: Maximum 200 m
Motor Power: Maximum 500 kW
Applicable Temperature: -98℃ to +150℃ (Suitable for non-crystallizing and non-solidifying media)
Applicable Viscosity: Maximum 150 cP

Note that specific values ​​may vary slightly depending on the time period or source (e.g., some data show a maximum flow rate of 600 m³/h and a maximum head of 450 m). It is recommended to refer to the latest data from the Dalian Imperial website or the technical sample used for specific model selection.

🏭 Application Industries: Where can you find it?

With its zero-leakage and high reliability, the basic model (F series) is widely used in many industries with strict requirements for safety, environmental protection, and media purity.

Petrochemical Industry: One of the most reliable choices for conveying organic and inorganic chemicals, solvents, flammable, explosive, and toxic media in chemical processes. For example, in 2025, Fangchenggang Maple Leaf Grain and Oil purchased an Imperial canned motor pump, model F0810U-617, for transporting vegetable oil at 200℃. This is a very typical and time-sensitive application case.

Refrigeration and Air Conditioning: Used in central air conditioning, cold storage, and other systems for circulating refrigerants (such as ammonia and Freon). Its low noise and leak-free characteristics are ideal for such applications.

Nuclear Power and Aerospace: Due to its extremely high reliability, it is used in nuclear power plants to transport radioactive or special media liquids, and to fuel rocket propellants for satellite launch centers.

Other Fields: It is also widely used in pharmaceuticals, vacuum systems, high-pressure systems, and for transporting valuable liquids or special media that deteriorate upon contact with air.

💡 Summary: The core value of the Imperial canned motor pump basic model (F series) lies in its mature and reliable structural design, providing the highest level of safety assurance for the transport of clean media under normal operating conditions.

The actual cases in the procurement announcement show that even at temperatures of 200℃ (exceeding the basic model's recommended range of 150℃), the F series can still handle high-temperature media transportation tasks such as vegetable oils by selecting appropriate materials and configurations. This demonstrates the F series' strong adaptability to various operating conditions. Whether it can meet your specific needs requires a comprehensive assessment based on parameters such as the characteristics of your medium, temperature, pressure, and flow rate.
