Paint, ink and resin ask two things of a pump: move them gently so they do not break down, and be safe around solvents. The QBY does both. Its low-shear stroke preserves the body and finish of coatings and pigments, and its spark-free air drive is at home in solvent-laden areas.
It self-primes from drums and totes, handles high viscosity, and flushes easily for colour changes. Fit FKM or PTFE diaphragms for aggressive solvent systems, NBR for oil-based products.

Applications: paint and coatings, printing ink, resin and gum, pigments, adhesives, detergents and shampoo, lotions and emulsions
