Can I pump inks with this type of pump? (Similar questions are asked concerning paints and adhesives and can be answered in a similar manner).

Yes, but prior to making a pump selection you need to know if the fluid is a solvent or water-based product. What is the viscosity and temperature of the product? Generally if the fluid is solvent based, a good choice is nylon or aluminum models with PTFE elastomers. When pumping chlorinated solvents, 316 SS models are the best choice.
