What pump should be used for the bottom oil from the vacuum distillation tower?

Thread Content

Distillation tower bottom residue, temperature 330, high content of solid impurities. Previously, AY pumps were used; their operation cycle was short and they required frequent maintenance. May I ask, which pump would be more suitable?

The seal keeps failing; switch to the PLAN32 solution

For the bottom pump of the vacuum tower, I chose the AYII model~~~ The sealing solution selected is 32+53b~~ Apart from one shutdown due to operational issues shortly after it was put into use, it has been running continuously for almost 3 years now~~~
