The airless high-pressure pumps of the PROFESSIONAL series are best suited for use in paint circulation systems.
Thanks to their high pressure transmission, these models are particularly suitable for highly viscous, poorly soluble and solvent-free materials with a high solids content, e.g. zinc primers, solvent-based micaceous iron ore, glass flakes, printing inks, flame protection and other heavily pigmented or fibrous materials. The large displacement ensures slow piston movement even when working with large nozzle openings, and accordingly low wear.
This makes the units particularly suitable for use in automatic spray painting systems with or without circulation.
