What is a good choice for the packing seal in vertical clean water centrifugal pumps?
Thread Content
37kw, for a heating circulation pump; the medium is hot water at around 70 degrees. What type of packing would be suitable?
Graphite PTFE packing, asbestos-impregnated graphite packing; the use of asbestos-containing materials is not recommended.
Tetrafluoroethylene packing is not wear-resistant; aramid is wear-resistant, or a mechanical seal can be used

Mechanical seals are recommended; do not use packing
It’s better to use mechanical seals; although using packing seems cheaper for pumps, it actually results in increased labor costs or reduced reliability, which is not worth it~~~~
To prevent leaks and save electricity, switch to a mechanical seal!
Change it to a single-end face seal; it costs little money, the water injection is stable, and there are generally no problems.
That’s right. It is recommended to use a mechanical seal directly, to solve the problem once and for all
