Pipeline pumps are used only for transporting materials; how should one select a pipeline pump that cannot be used for pumping air?

Currently, there is a vertically arranged pipeline for high-viscosity materials; relying on gravity to transport the materials downward is too slow, so a pipeline pump is needed to move the materials. However, safety considerations prevent vacuuming out the materials before pumping air in. It is required that the pipeline pump be used only for transporting materials, not for pumping air; it should feed material without drawing in air. How should one choose?
You could consider a screw pump, namely a screw pump with a rubber stator.
Screw pumps and rotor pumps can both be used to achieve this
If the viscosity is no more than 600 centipoise, a centrifugal pipeline pump can be considered; either level control or pressure control can meet your requirements. Beyond this range, if there are no solid particles, a gear pump can be used; it doesn’t take up much space, but flow rate might be an issue.
There may be a risk of vacuum formation, and dry grinding of the rotor is a concern
What are the advantages of rotary pumps over screw pumps? ? ?
