Working Principle & Features:
A pneumatic motor pressurizes the hydraulic section with a ratio of 40:1. Oil then transmits the pressure to the pumped fluid through the two diaphragms which deliver the material. A special inlet valve allows high frequency operation, i.e. a high delivery rate can be achieved with a comparable small pump volume. In addition: Solvent consumption and material waste is reduced during flushing and color-changes. Special feature: It is the first high pressure pneumatic pump without packing. As the pump is completely sealed (no contact between fluid and atmosphere) and generates only a minimum of shear it can be also used with critical coatings such as reactive paints (e.g. UV paints).
Airless and Air Coat applications up to 250 bar in furniture, construction, metal industry, general purpose finishing (incl. water and solvent-based paints, moisture-sensitive materials, shear-sensitive coatings, UV-cure materials and temperature reactive materials). The pump is also suitable for highly abrasive materials.
