Can the pump run on steam for a long time?
Thread Content
The unit was shut down for purging; during the purging process, the supervisor ordered that the pump be purged using steam for an extended period of time. Was it possible to purge the pump with steam for such a long time? Thank you, everyone please share your thoughts; extra points for that
Plastic pumps won’t work, right? For metal pumps, it’s not a big problem if the sealing area can’t be reached?
It still depends on what type of pump it is and what medium it handles regularly
Check whether the pump’s seals can withstand high temperatures

Steam purging is not recommended. Centrifugal pumps have a complex internal structure; as steam flows through them, pressure losses and temperature drops occur, causing some of the steam to condense. The condensed droplets exert significant stress on the pump due to the thrust generated by the steam
A short period of time poses no problem for high-temperature oil pumps.
Steam purging of centrifugal pumps should be handled differently depending on whether high or low temperatures are present. What exactly does long-duration purging mean? The purpose of performing purging during shutdown is to clean the pump and pipelines thoroughly. Pumps usually have bypass lines, and once it is confirmed that the pump has been cleaned, steam can be directed through these bypass lines rather than through the pump itself, thereby continuing the purging of the pipelines.
