I. Overview of HYC Leak-Free Submersible Magnetic Pump


The HYC Leak-Free Magnetic Drive Submersible Pump is a type of pump designed for applications requiring complete sealing during the conveying process of media, featuring a submersible structure. The lower part in contact with the liquid is entirely made of stainless steel, with a submersion depth of 1 to 6 meters. The main pump unit is fully immersed in the liquid, utilizing a static seal design without traditional mechanical seals, ensuring complete isolation from external air. It truly achieves zero leakage and is particularly suitable for flammable, explosive, toxic, and high-risk media. It boasts wide corrosion resistance, high efficiency, a safe and reliable shaft connection structure, easy disassembly, and can pump without the need for filling liquid. The pump operates silently due to the support of rolling and sliding bearings for the axial and radial forces generated during operation. It is a high-tech, sustainable product that combines environmental protection with energy saving, characterized by strong corrosion resistance, good wear resistance, high mechanical strength, food-grade quality, reasonable design, compact structure, reliable performance, ease of maintenance, high efficiency, and energy efficiency.


II. Advantages of Magnetic Submersible Pumps


The HYC Leak-Free Magnetic Drive Submersible Pump is a new, energy-efficient submersible centrifugal pump designed in accordance with national standards, featuring no-leakage technology.

2. Flow components such as pump bodies, inner rotors, pump covers, impellers, isolation sleeves, and shafts can be made of materials like 304, 316, 316L, 904, TA2, HC276, etc.

3. The pump body and cover are designed with CFD (Computational Fluid Dynamics) for hydraulic components, featuring modular design and precision casting. They should withstand the erosion from high-speed, high-pressure fluids and the impact of sudden thermal shocks, possess high cavitation resistance, precise dimensions, and smooth flow paths, ensuring the pump's corrosion and pressure resistance.

4. The impeller is also designed with CFD computational fluid dynamics for hydraulic components, featuring modular design and precision casting, ensuring reliable torque transmission. Its closed structure, optimized flow channel design, high efficiency, and low NPSHR value guarantee stable pump flow and head.

5. The isolation sleeves are made of materials such as 316L, TA2, HC276, and feature a low eddy current design. The sleeves are placed in a sine wave alternating magnetic field, where they induce eddy currents perpendicular to the magnetic field lines, converting them into heat. Isolation sleeves can be made from high-resistivity, high-strength non-metallic materials, which significantly reduce eddy currents, eliminating excess heat and reducing energy consumption. They have high bursting pressure resistance and a high safety factor. Additionally, they completely isolate the pump chamber from the outside, ensuring the pump room is fully sealed, achieving zero leakage during the conveying process.


6. The dynamic rings, shaft sleeves, and sliding bearings are made of high-wear and high-temperature resistant materials such as crystalline silicon carbide and tungsten carbide. They offer high strength, excellent wear resistance, good flexibility, and strong corrosion resistance, effectively extending the pump's service life. Rolling bearings use imported NSK or SKF grease-lubricated, maintenance-free bearings.

7. The magnetic blocks are selected with a neodymium-iron-boron ratio of 2:17, offering a magnetic energy product of 28兆 Gauss Oersteds. They can withstand a maximum temperature of 350°C, greatly reducing the risk of demagnetization, thus ensuring a theoretical lifespan of up to 20 years for the magnetic material.

8. The pump's axial force self-balancing structure utilizes hydraulic principles to automatically balance the axial force through fluid pressure difference. The thrust plate of the rolling bearing only bears unbalanced axial force during start-up and shutdown. This achieves almost zero axial force at operating conditions, significantly enhancing the overall stability of the machine's operation.

9. Magnetic pumps feature a dual sliding bearing design for smoother operation, ensuring unobstructed medium flow and optimal lubrication of the sliding bearings; the structure of the sleeve and elastic gasket within the sliding bearings extends the bearing's lifespan, reduces pump vibration, and prevents cracking of the sliding bearings due to high-temperature conditions.

10. Leak-free, all sealing points utilize closed-type static seal, powered by magnetic couplings, no need for nitrogen sealing. It is safe, economic, and efficient, and completely resolves medium leakage issues.
