Applications of Imperial canned  Pumps (Model F) in the Refrigeration and Air Conditioning Industry

The Imperial Shielded Pumps (Model F, Basic) have a wide and mature application in the refrigeration and air conditioning industry, considered a classic configuration. Their absolutely leak-free, low-noise, and compact structure perfectly meets the stringent safety and environmental requirements of refrigeration systems.

🏆 Market Position: Industry Benchmark and Core Supplier

In the refrigeration and air conditioning field, Dalian Imperial Shielded Pumps enjoys extremely high market recognition. Its official customer list almost encompasses all the leading brands in the industry in China:

Dalian Sanyo

Jiangsu Shuangliang

Yantai Ebara

Sichuan Shenlan

Qingdao LG

These companies are market leaders in lithium bromide absorption chillers. Their standard or designated use of Imperial Shielded Pumps in their products fully demonstrates the reliability and technological leadership of the F series in the refrigeration industry.

🔧 Core Application: The "Heart" of Lithium Bromide Units

The most core application of the F series shielded pumps in the refrigeration industry is as a key power source for lithium bromide absorption chillers. In these types of units, two types of pumps are typically required, and the F series can perfectly handle both:

Pump Type | Function | Why Choose the F Series

Solution Pump | Responsible for circulating lithium bromide solution (a salt solution), which is the medium for the unit to absorb and release heat. The zero-leakage characteristic of the F series ensures that the highly corrosive lithium bromide solution will not leak, protecting equipment and the environment.

Refrigerant Pump | Responsible for circulating refrigerant water (which evaporates and absorbs heat in a vacuum environment to produce a cooling effect). The F series has a compact structure and low noise, making it ideal for air conditioning units with requirements for operating environment and space.

A 2021 procurement notice for lithium bromide units explicitly required that the matching shielded pumps (including solution pumps and refrigerant pumps) be from the "Dalian Empire" brand. This demonstrates that in the professional engineering field, the Empire F series remains synonymous with high-end and reliable performance, a key component in ensuring the long-term stable operation of the entire refrigeration system.

💡 Why is the F series the ideal choice for refrigeration and air conditioning?

Ensuring Cooling Efficiency: The leak-free characteristic of the shielded pump ensures a high vacuum level inside the unit. For lithium bromide refrigeration, vacuum is the lifeline for maintaining efficient evaporation; even the slightest leak will disrupt the vacuum, leading to a significant drop in cooling capacity. The F-series fundamentally eliminates this problem.

Quiet and Environmentally Friendly Operation: The F-series operates without fans or couplings, making it extremely quiet, which is crucial for installations inside buildings or in environments with noise restrictions. It also prevents refrigerant or solution leaks, making it an environmentally friendly choice.

Space-Saving Installation: Its integrated motor and pump modular structure is very compact, requiring little floor space and facilitating the overall design and layout of refrigeration units.

🚀 Technological Upgrades: Continuously Leading the Industry
Imperial canned pumps have not stopped at meeting existing needs but continue to innovate. For example, in 2016, Dalian Imperial independently developed a 10,000-volt, 500-kilowatt high-voltage canned pump. This high-end product can also serve key national projects such as the State Grid's large-scale DC transmission projects. This demonstrates its technological reserves in the high-voltage, high-power field and opens up possibilities for larger-scale industrial refrigeration or heat pump systems in the future.
