Everyone, our company has a vacuum distillation tower. What type of pump should be used for the bottom circulation pump? What form of sealing will be used? The pressure in the tower is 10 Pa (gauge pressure), and the liquid level at the bottom of the tower is 1 M. The distance from the bottom of the tower to the pump inlet is 6 M. Flow rate and head are not mentioned here.

High-temperature centrifugal pump, equipped with a mechanical seal that uses dual cooling water for sealing

Shielded pumps or magnetically driven pumps are generally used in vacuum distillation systems.
