Precautions for operating magnetic pump
Thread Content
We had been using canned pumps in the past, but due to the high temperature of their pump bodies, we opted for magnetic drive pumps when storing styrene monomer. However, I heard from colleagues in the area that magnetic drive pumps tend to burn out easily. Could those with more experience please share any relevant operational precautions? Thank you! I work at a public chemical terminal, and I hope to meet some professionals in the field of storage and transportation equipment.
Just make sure there is no interruption in the flow, and also check the direction of rotation of the motor when starting the pump
To ensure no idling, the other operations are basically the same as those for a centrifugal pump.
The original poster can refer to the encyclopedia on “magnetic pump”; it provides very detailed information there!
1. It must be operated within the operating temperature range of the magnetic pump; otherwise, the magnetic cylinder is prone to demagnetization and the pump will not be able to generate pressure. 2. No idling
Thank you all. During this period, I also conducted specialized research on magnetic pumps, adding flow interruption protection and temperature monitoring in the gap area.
There must also be no impurities in the materials. Otherwise, the bushing will run out quickly.

In addition to the precautions mentioned by those upstairs regarding no idling, no reversal of rotation, and no interruption in flow, it is also important to pay attention to the issue of the pump’s net positive suction head. This is especially true for centrifugal pumps; this aspect must be properly considered in system design, otherwise it can lead to serious problems.
