I have read 4 web pages
TEIKOKU (Empire) is a technology pioneer and market leader in the field of shielded pumps. Its Japanese parent company, Imperial Electric Machinery Co., Ltd., was founded in 1939, while its Chinese joint venture, Dalian Imperial Shielded Electric Pump Co., Ltd., was established in the 1990s and was the first professional manufacturer of shielded pumps in China. Dalian Empire fully adopts the full set of technology and standards from its Japanese parent company, therefore the technical features and applications introduced below represent both TEIKOKU's global level and are fully applicable to Dalian Empire's products.

🛠️  Structural characteristics of TEIKOKU vertical shielded pump
The core design concept of TEIKOKU shielded pump is "leak free", which integrates the motor and pump into a fully enclosed unit. The inner surface of the stator and the outer surface of the rotor are each sealed and welded with a corrosion-resistant metal sheet (shielding sleeve), which completely separates the stator winding, rotor core, and the conveyed liquid.

Overall structure
Integration of motor and pump: adopting a "building block" structure design, the motor is directly connected to the pump body, with a very compact structure, small volume, light weight, and small footprint.

Rotor immersion: The impeller and rotor are mounted on the same shaft, and the entire rotor body is immersed in the conveying fluid.

No shaft seal: The pump has no dynamic rotating parts that are connected to the outside world, achieving absolute leak free structure.

Fanless cooling: The motor does not have a cooling fan and operates with very low noise.

key component
Structural characteristics of components
The inner surface of the shielding sleeve stator and the outer surface of the rotor are sealed and welded with non-magnetic and corrosion-resistant metal sheets, completely isolating the liquid from contact with the stator winding and rotor core.
The bearing motor is equipped with sliding bearings at both ends, and the entire rotor is lubricated and cooled by the conveying fluid itself. The main maintenance work is to replace the bearings.
The conveying fluid of the circulation system enters the motor chamber through the internal circulation path for cooling the motor and lubricating the bearings. There are multiple circulation modes based on the characteristics of different media.
Main derived models and special structures
TEIKOKU has developed a variety of derivative products for different working conditions, which is a reflection of its technological strength:

Model series applicable working conditions, core structural characteristics
Basic type (F-type) is a medium that is non crystalline, non solidifying, and particle free, with a temperature of<150 ° C. Standard structure, suitable for the vast majority of conventional leak free transportation scenarios.
The internal circulation basic type (F-V/FA-V type) is similar to the basic type, but requires higher safety. The motor circulating fluid enters the motor chamber directly through the end cap hole, and then returns to the impeller inlet through the rotor shaft inner hole, eliminating the external circulation pipe and reducing potential leakage points.
Reverse circulation type (R/RA type) easily vaporizes liquids, such as low-temperature liquefied gases like LPG and LNG. The lubrication and cooling path is opposite to the basic type, and the motor circulating fluid can be discharged to the gas phase area of the inlet tank to ensure that there is no gas in the motor chamber, ensuring bearing lubrication and motor cooling.
High temperature separation type (BA type) high-temperature liquids, such as heat transfer oil and hot water, can reach a temperature of 350 ° C (specially designed 450 ° C). Equipped with a connecting body (heat shield), heat exchanger, and cooling jacket to isolate heat conduction. Forced circulation of coolant by the secondary impeller.
Self suction type (G-type) extracts liquid from underground containers, with a suction height of up to 5 meters. It has an automatic exhaust function, and when the suction pipeline is not filled with liquid, the pump body can automatically exhaust to lift the liquid.
High melting point type (K-type) is a high melting point liquid that is prone to crystallization. The pump body, circulation pipe, end cover, and connecting body are all equipped with insulation sleeves, which can be fully preheated before starting up to prevent medium crystallization.
Mud sealed type (DA type) is a liquid containing a small amount of soft particles. The motor chamber and pump chamber are separated by a mechanical seal, and an external injection tank is filled with clean mother liquor or solvent to prevent particles from entering the motor chamber after pressurization.
Gas sealed mud type (X-type) high viscosity, easily polymerized liquid or high concentration, large particle mud (content<30%, particle size<0.2mm). There are mechanical seals and gas seal chambers between the pump and motor, which are isolated by gases such as nitrogen to prevent bearing wear caused by the conveying fluid.
Ultra heat-resistant (F-X type) high-temperature liquid. Motors made of special ultra-high temperature insulation materials can be used to transport high-temperature liquids without cooling, saving energy.
Multi segment (F-M type) high head requirement (maximum head 450m). Equipped with multiple impellers, the impellers adopt a "back-to-back" distribution to maximize the balance of axial thrust and have a compact structure.
Monitoring and Protection System: TRG
TEIKOKU's unique technology - TRG (Imperial Operation Protection) monitoring system, can monitor bearing wear in real-time during operation. The principle is to install two differential pressure connected coils inside the motor stator, and determine the bearing clearance by monitoring the output potential changes (indicated by the pointer in the green/yellow/red zone), reminding the operator to take timely measures. In addition, temperature protection, idle protection, etc. can be configured.

Adopting a fully enclosed structure with no leakage, it is suitable for transporting high-temperature, dangerous, toxic, and valuable liquids.
The bearing and lubrication motor are equipped with sliding bearings at both ends, which are lubricated and cooled by the conveying fluid itself. This is a universal design for shielded pumps and a key component that determines the operational lifespan of the pump. NIKKISO has a deep accumulation in bearing materials and fluid dynamic lubrication design, ensuring long-term reliable operation.
The conveying fluid of the circulation system enters the motor chamber through the internal circulation path for cooling the motor and lubricating the bearings. According to the characteristics of the medium (easy gasification, high temperature, particle content, etc.), different circulation modes can be configured. NIKKISO has mature solutions for special structures such as high-temperature separation and reverse circulation.
Monitoring and protection can be configured with bearing wear monitoring, temperature protection, idle protection and other monitoring systems to ensure that the pump can alarm or shut down in a timely manner under abnormal working conditions. NIKKISO has independently developed monitoring and protection technology, which forms a benchmark with TEIKOKU's TRG system.

Structural characteristics and application industries of HERMETIC vertical shielded pump
I have read 10 web pages
Like TEIKOKU and NIKKISO that you previously learned about, HERMETIC is also a technology pioneer and leader in the global field of shielded pumps. It originated in Germany and was founded in 1875. Since 1951, it has been manufacturing shielded pumps and has delivered over 180000 units worldwide, making it the largest shielded pump manufacturer in Europe. In China, Dalian Haimitike Pump Industry Co., Ltd. is a joint venture with Dalian Danai Pump Industry Co., Ltd. and is also one of the core enterprises in the field of shielded pumps in China.

HERMETIC, with its unique technology in the fields of high temperature, high pressure, and high safety (such as ZART) ® Known for its zero thrust technology and MAP rotor monitoring, it has a deep foundation in API 685 standard shielded pumps and nuclear grade pumps.

Below is a detailed analysis of the structural characteristics and application industries of HERMETIC vertical shielded pumps.

🛠️  Structural characteristics of HERMETIC vertical shielded pump
The core design concept of HERMETIC shielded pump is "no leakage, high reliability". Its vertical series inherits the universal advantages of shielded pumps and incorporates multiple exclusive patented technologies.

Overall structure
Characteristics and Description of Structural Components HERMETIC Technology Features
The motor and pump are integrated into a closed unit, with the rotor and impeller sharing the same shaft and completely submerged in the conveying fluid. No mechanical seals or couplings, fundamentally eliminating dynamic leakage points. The vertical structure does not require long shafts and intermediate bearings, occupies a small area, is easy to install, and is particularly suitable for situations with limited space or installation in pools.
The inner surface of the stator and the outer surface of the rotor are sealed and welded with corrosion-resistant metal sheets (shielding sleeves) to completely isolate the stator winding from the conveying fluid. HERMETIC stator shielding sleeves are usually made of advanced materials such as Hast-C4, which have strong corrosion resistance and ensure absolute sealing.
The bearing and lubrication motor are equipped with sliding bearings at both ends, which are lubricated and cooled by the conveying fluid itself. During normal operation, the bearing is completely non-contact with the shaft (supported by a liquid film) and theoretically has no wear. The sliding bearing is made of crystalline silicon carbide (SSIC, SIC30) material, which has high hardness and good wear resistance.
The conveying fluid of the circulation system enters the motor chamber through the internal circulation path for cooling the motor and lubricating the bearings. According to the characteristics of the medium, different circulation modes can be configured. For easily vaporized media, high-pressure internal circulation is used to ensure that the motor chamber is always filled with liquid, preventing cavitation and bearing dry wear. For high-temperature media, an external cooler can be used to form an independent low-temperature circulation loop.
Core patented technology: ZART ® design philosophy
HERMETIC's most unique core technology is ZART ® The design philosophy of "Zero Axial and Radial Thrust" refers to the concept of "zero axial and radial thrust". Its core is to achieve precise fluid dynamic pressure balance design, so that the rotor does not come into contact with the bearing at all during operation, thereby realizing:

ZART ® Specific manifestations of advantages
Safe against damage, ultra-low emissions, each pump has a secondary safety shell guarantee.
Extremely low lifecycle cost, low cost of unexpected downtime, and low maintenance expenses.
The highest reliability mean time between failures, no contact=no wear=no worries, suitable for the most demanding working conditions.
HERMETIC's CAMTV vertical shielded pump is specifically designed for low-temperature applications such as LNG/LPG and ethylene, using ZART technology ® Technical and magnetic support bearings ensure no contact in both static and operational states.

Advanced monitoring system: MAP rotor monitoring
HERMETIC's unique MAP system (based on LVDT rotor position monitoring) can continuously monitor the axial position of the rotor, which is a reliable indicator for judging bearing wear and abnormal working conditions, reminding operators to take timely measures to prevent faults from occurring.

In addition, temperature monitoring, steering monitoring (ROMi), liquid level monitoring, motor load monitoring, etc. can also be configured.

Main derived models
HERMETIC has developed a wide range of derivative products for different working conditions. The following is a typical series of vertical pump models:

CAM/x+y type (multi-stage high pressure) with high head and high pressure requirements, capable of up to 12 stages. HERMETIC's unique "shoulder style" design avoids vibration and shaft damage caused by cantilever shafts.
CNF type (single-stage standard/liquefied gas type) transports easily vaporized media (such as LPG, ammonia, refrigerant), with a vaporization pressure greater than 0.05MPa. Adopting high-pressure internal circulation without external pipelines, the motor and bearings are cooled and lubricated by the medium itself.
CNK+D type (mud type) medium containing a small amount of solid particles. The combination of main pump and metering pump continuously injects clean medium to prevent particles from entering the motor chamber and damaging the bearings.
High temperature type (with external cooling) high temperature liquid, up to+480 ° C (special design can reach+450 ° C). The pump and motor are separated by a thermal screen (intermediate piece), and the auxiliary impeller drives the external cooler to circulate, keeping the temperature in the motor chamber at+60 ° C to+80 ° C.
Low temperature/immersion type liquefied gases, with a minimum temperature of -196 ° C, such as LNG, liquid nitrogen, ethylene, etc. The whole machine is immersed in a low-temperature medium, and the motor is cooled by the medium, resulting in higher efficiency. No dynamic sealing, extremely reliable.
