What is the Working Principle of Canned Motor Centrifugal Pumps?

Teikoku canned motor centrifugal pumps operate on the centrifugal pump principle. Manufactured in Japan, these pumps are capable of functioning under high temperatures and vacuum conditions. When electricity is supplied to the stator windings, a magnetic field is generated in the stator, causing the rotor to rotate. This rotation, driven by the fan attached to the rotor, enables fluid transfer.

The carbon bearings located at the right and left ends of the rotor keep it stable and are resistant to high temperatures. The fluid moves around the rotor and exits the pump, but a portion of the fluid is directed inside the pump to lubricate the carbon bearings and cool the motor.

These pumps are manufactured in a wide variety of types to meet the technical requirements of different processes and aim to be the most reliable pumps in industrial facilities.

What are the purposes of using Teikoku canned motor centrifugal pumps?

Teikoku canned motor centrifugal pumps are primarily designed to eliminate leakage problems that may arise from fluids with high temperatures or those posing safety risks due to leaks. They are seal-less and prevent fluid leakage thanks to their canned motor design. With high heat resistance, they are customer-friendly in terms of maintenance costs and operate reliably in processes without causing issues. Additionally, as the fluid serves as a coolant, the motor does not require a fan, enabling quiet operation. Teikoku canned motor centrifugal pumps can also operate in EX-PROOF (flammable and explosive) environments.

What are the processes in which Teikoku canned motor centrifugal pumps are used?

Teikoku canned motor centrifugal pumps are commonly used in hot oil processes. Additionally, they are extensively utilized by oil production companies and for the transfer of fluids such as formaldehyde and methanol.

What are the material properties of Teikoku canned motor centrifugal pumps?

Teikoku canned motor centrifugal pumps can be manufactured using materials such as 304 SS stainless steel, 316 SS stainless steel, Hastelloy, and titanium.

What are the capacity and other operating values of Teikoku canned motor centrifugal pumps?

Teikoku canned motor centrifugal pumps can achieve very high capacity values, with a maximum capacity of 2400 m³/h. The maximum head is 700 meters, and the maximum design pressure is 560 bar. The maximum design temperature is 450°C, and they can be operated with a motor of up to 550 kW.

What are the advantages of Teikoku canned motor centrifugal pumps?

Teikoku canned motor centrifugal pumps are seal-less, providing a significant advantage in terms of maintenance costs and ensuring leak-proof operation. They come with all necessary quality and safety certifications. With no coupling, they offer high energy efficiency. These pumps are suitable for vacuum processes, reducing internal pressure to prevent oil combustion.

Compared to alternatives, their smaller size saves space in facilities. In hot oil processes, with proper use, the carbon bearings and rotor can last 8-10 years. Labor costs are low, as maintenance only requires removing the shaft sleeve. External lubrication is unnecessary.

Teikoku pumps feature a TRG monitor, allowing users to detect internal wear without disassembling the pump. Since the motor lacks a cooling fan, they operate quietly. Their leak-proof design makes them ideal for handling toxic, explosive, expensive, hazardous, carcinogenic, and corrosive fluids.
