Applications

Airless and Air Coat applications up to 250 bar in furniture, construction, metal, general finishing (including water and solvent based paints, moisture sensitive materials, shear sensitive coatings, UV curing materials and temperature reactive materials). The pump can also handle highly abrasive and aggressive materials.

Working Principle & Features

A pneumatic motor pressurizes the hydraulic section at a ratio of 40:1. The oil then transfers the pressure to the fluid being pumped through the two diaphragms that deliver the material. A special inlet valve allows high frequency operation, i.e. a high flow rate can be achieved with a comparably small pump volume. In addition: Solvent consumption and material waste during rinsing and color changes are reduced. Since the pump is completely sealed (no contact between fluid and atmosphere) and generates minimal shear, it can be used with critical coatings such as reactive (e.g. UV) coatings.
Special feature: It is the first high-pressure pneumatic pump without packing.
