Will high-temperature magnetic centrifugal pumps lose their magnetism after long-term use?
Thread Content
The heat oil pump currently in use is of the WRY type, manufactured by Changzhou Wujin No.1 Heat Oil Pump Factory. (Is it one of the higher-quality pumps available in China?) ). But there are also frequent leaks. I now want to switch to a magnetic drive centrifugal pump. (Shielded pumps are expensive, and they also require external cooling water, which is rather troublesome.) There are now high-temperature versions of magnetic drive centrifugal pumps – will their magnetism fade over time with prolonged use?
Provide the supplier with comprehensive and accurate operational parameters, so that the supplier can select the appropriate configuration; as long as it operates within the specified process conditions, demagnetization will not occur.
There are high-temperature magnets; what is the temperature of your medium?
Use a stainless steel magnetic pump with samarium-cobalt magnets. We have customer instances, and the temperature is fine there.
Could you introduce some manufacturer brands that offer pumps as well as those that don’t?
A specialized magnetic pump can be designed based on your operational conditions, and it will not lose its magnetism over time
