Starch is derived from corn, arrowroot, or potatoes. It is shear sensitive (thickens) and viscosity varies from a few centipoises to over 20,000 cP depending on the type of starch, concentration in the liquid, and temperature.

Viking pumps are used in the starch mixing and delivery systems (sometimes called kitchens) at paper mills and corrugators. Construction varies from cast iron to stainless steel, depending on the type of starch. Most starches are neutral or basic and are handled using cast iron. Starches that are more acidic may require stainless steel.

Raw starch may be abrasive if not completely dissolved or allowed to dry out. Cooked or hot starch (typically160°F) is not abrasive.
