Problems with centrifugal pump disc pumps
Thread Content
When stopping a centrifugal pump, a slight friction sound can be heard at the mechanical seal – what are the common causes of this? Is it necessary to take action? When operating the magnetic pump, a slight friction sound can be heard from the outer magnetic cylinder

The slight noise from the mechanical seal that you described is likely caused by the vibration of the elastic elements resulting from rotation
There’s no problem with this situation, right? Some have a slight noise, while others don’t. Is it possible that the mechanical seal is tightened too much? Magnetic pump units can also occasionally produce slight friction noises
I’m not sure about magnetic pumps. For modular mechanical seals, such noises are not a problem; for non-modular seals, it is essential to strictly follow the installation and operation instructions in order to control the working height of the elastic element
It is normal to have some friction when stopping; if there were no resistance, then it wouldn’t stop
When operating a magnetic pump, a slight friction sound can be heard from the outer magnetic cylinder. Is it a new pump? It might be due to the gap between the external magnet and the isolation sleeve. The structure of the magnetic pump is relatively simple; if it’s possible, it’s recommended to open it and take a look.
It is normal for a new mechanical seal to produce frictional noises during the initial installation phase; the rubbing surfaces generate slight frictional sounds when they are not lubricated. There is nothing to worry about
Small screeching noises can occur even in the absence of materials; it might be due to dry grinding of the mechanical seal. We check the pump every day; there are noises sometimes due to materials present, but it starts up normally, so we don’t worry about it!
