New pump generation with contactless changeover valves
Dürr has developed a new generation of pneumatic vertical piston pumps that increases process reliability yet requires much less maintenance.
The new “EcoPump2 VP” pump only needs one seal for the majority of applications, which is quicker and easier to change than on the predecessor model. The fluid parts can be disconnected from the air motor with conventional tools via a quick coupling. The new air motor can be operated without any oil.
This significantly reduces the maintenance required, including in comparison with the competition. A further benefit is that the contactless changeover valves used to regulate the air motor changeover guarantee higher process reliability. Using quick-exhaust valves cuts changeover times, reduces pulsations, and increases performance.
With five different versions of the covering a pressure range from 22 to 306 bar, the pump is suitable for applying paints, high-viscosity materials, and adhesives to furniture, steel constructions, and many more materials. It can also handle acidic hardeners commonly used in the 2K process in the North American market.
