During the vacuum distillation of coal tar, how do vacuum pumps prevent tar from entering the pump? Or what kind of new pumps can be used to prevent tar from entering the pump and damaging the pistons?

A screw vacuum pump equipped with cleaning and purging devices can be used to prevent tar from accumulating inside the pump

Is there a simple process diagram? Is this how it’s used in industry?
