What type of pump is commonly utilized for transporting high-viscosity materials?

The choice of a positive displacement pump for transporting high-viscosity materials is correct because these pumps are specifically designed to move fluids with thicker consistency, where standard centrifugal pumps may struggle or become inefficient. Positive displacement pumps function by trapping a fixed volume of fluid and then forcing that volume into the discharge line. This mechanism allows them to maintain a consistent flow rate regardless of the pressure, which is crucial when dealing with viscous substances that require a high degree of control over pumping rates.

Unlike centrifugal pumps, which rely on velocity and centrifugal force, positive displacement pumps can effectively manage the thicker materials without causing significant shear stress or turbulence. This makes them ideal for applications involving oils, slurries, or other materials with high viscosity.

Other pump types, such as diaphragm pumps or rotary gear pumps, can also be used for high-viscosity materials in certain scenarios, but a positive displacement pump is generally the most versatile and reliable choice for this specific application.
