Magnetic pump and shielded pump – what is the current quality level of domestically produced ones?
Thread Content
The quality of magnetic pumps and shielded pumps from countries in Japan, South Korea, Europe, and the United States is good. What is the current level of design and manufacturing for domestic products? China is a major country in the field of rare earth permanent magnets; how is this industry developing at present? Reputable manufacturers don’t rely on Baidu for promotion; customer forum members have the most say. It seems there aren’t many posts related to this topic ； Top 10 companies worthy of attention for design, manufacturing quality, and reliability? Top 5? The top 3?
The development is average, as previous high-end products have become mediocre. For these two types of pumps, there is basically no best one – only the most suitable one. Magnetic pumps are still better when imported; domestic magnetic materials are acceptable, but the pumps themselves are not good enough. There’s a Dandong clone; Dalian Kehuan can be checked out. It’s hard to say that foreign-made shield pumps have any particular advantages; domestic brands like Huanyou and Xinhu are now quite good.
Use a magnetic pump instead of a shielded pump, and use a centrifugal pump instead of a magnetic pump. Shielded pumps: Nikkiso, Dalian Haimi antimony ke; in China: Huanyou, Xinhu. Magnetic pump: Clone, a company based in the South. Don’t think about anything else; once a shielded pump is used, just wait until it’s time for major repairs and to return it to the factory
Imported shielded pumps: Hammett and Empire. Nikkiso’s pump technology is limited; there are some types of pumps that it cannot manufacture. Among the domestic shielded pumps we have used, those from Dalian Jinshi, Dalian Huanyou, and Hefei Xinhu are all satisfactory. The first brand uses Hammett’s technology, and its spare parts are available; the latter two brands use Empire’s technology
