Tall Oil

Other Names: Tallol, liquid rosin

Viscosity: Varies widely, depending on source of tall oil and stage in process. Can vary from 220 to 560 cPs. Generally handled in the temperature range from ambient to93°C / 200°F.

Remarks: Tall oil is the oily mixture of rosin acids, fatty acids and other materials obtained by acid treatment of the alkaline liquors from the digesting of pine wood. The spent black liquor from the pulping process is concentrated until the sodium salts of the various acids separate out and are skimmed off. These soaps are acidified by sulfuric acid to obtain the crude tall oil. Used in drying oils, alkyd resins, linoleum, soaps, cutting oils, emulsifiers, flotation agents, lubricants and greases, and in making rubber. Suggest checking with user or supplier of material to make sure materials of construction recommended for the pump are in keeping with materials in the rest of the system.

Pump Notes: Cast iron construction is satisfactory. Elastomer recommendation varies with specific product.
