Dalian Imperial Pumps' Ultra-High Temperature Resistant Model: Structural Features and Application Industries

The ultra-high temperature resistant model (F-X type) of Dalian Imperial canned motor pumps is a featured product in its high-temperature product line. Its biggest highlight is achieving high-temperature transport under "water-free" conditions. Compared to the high-temperature separation type, which requires a complex cooling system, its structure is simpler and its operating cost is lower.

🔧 Structural Features: From "Material Insulation" to "System Reinforcement"

If the high-temperature separation type protects the motor through "external cooling," the ultra-high temperature resistant type allows the motor itself to withstand high temperatures through "internal reinforcement." Its core structural features are mainly reflected in two aspects:

1. Core Foundation: Unique Material Insulation Technology

Water-free design: This is its most fundamental feature. The motor windings directly use special ultra-high temperature insulation materials, allowing the pump to continuously transport high-temperature liquids up to 380℃ without cooling water.

Reduced heat loss: Since the water cooling system is eliminated, there is no additional heat exchange loss associated with a water-cooled motor, resulting in lower heat loss and higher energy conversion efficiency during operation.

2. Enhanced Performance: Latest Patented Technology

To further improve reliability and adapt to more complex operating conditions, Dalian Imperial has developed a series of enhanced technologies on top of its existing foundation:

Full Jacketed Cooling (Expanding Application Areas): The latest full jacketed structure extends the cooling jacket from the front flange to the rear flange of the stator, covering the entire stator cavity. This significantly improves cooling efficiency, meeting explosion-proof requirements even in harsh environments with inlet media temperatures reaching 200°C and external heating steam temperatures reaching 155°C, effectively expanding its application areas.

Secondary Pressure Protection (Enhanced Safety): A secondary pressure-bearing structure with a pressure relief port, through the installation of a shut-off valve, safety valve, and pressure-bearing terminal block, achieves pressure relief and secondary pressure-bearing functions for the ultra-heat-resistant shielded pump. This reduces pump damage under abnormal conditions and significantly extends the equipment's service life.

High-Efficiency Rotor Structure (Improved Motor Efficiency): Addressing electromagnetic performance at high temperatures, a new rotor structure compensates for potential axial displacement at high temperatures by making the rotor core longer than the stator core at both ends, ensuring stable motor performance. Meanwhile, its end guide bars employ through-type reverse welding, eliminating the need for stainless steel sleeve protection and thus avoiding eddy current losses, further reducing motor heat generation.

🏭 Main Application Industries
With its waterless, compact, and low-energy-consumption features, the ultra-heat-resistant type primarily serves applications requiring high equipment simplicity and operational economy.

Application Industries Typical Scenarios and Uses Key Media

Petrochemical Industry: Used for conveying high-temperature process fluids in applications where extremely high pressure is not required or where readily available cooling water is unavailable. Hot oil, heat transfer oil, hot water, etc.

General Industry: Heating or drying systems in industries such as power transmission, shipbuilding, textiles, and food processing. High-temperature liquids

Clean Energy: Used as a circulating pump for heat transfer fluids in some solar thermal power generation or biomass energy projects. Heat transfer oil, molten salt (specific model needs confirmation)

Refrigeration and Air Conditioning: Used in certain industrial-grade large-scale absorption air conditioning or heat pump systems. High-Temperature Hot Water or Steam

💡 Summary and Selection Recommendations

In general, the core value of Dalian Imperial's ultra-heat resistant model (F-X type) lies in its use of breakthroughs in material technology to achieve advantages in system simplicity and operational economy.

When selecting a model, you can refer to the following ideas:

If your operating conditions involve a medium temperature below 380℃, and you want a simplified system, reduced energy consumption, and a clean medium—the ultra-heat resistant type (F-X type) is a very suitable choice.

If your operating conditions involve a medium temperature exceeding 380℃, or extreme situations involving both high temperatures (e.g., 450℃) and high pressures (e.g., 35MPa)—then you should consider the high-temperature separation type (B type) or the high-temperature and high-pressure series.

What are your specific operating conditions? For example, is the medium heat transfer oil or other process fluids? Besides temperature, what is the approximate system pressure? Tell me these parameters, and I can help you more accurately determine whether the F-X type is a good match, or recommend other more suitable models.
