Application and Functionality:

The WIWA Low Pressure Pump DA is designed for applying foundry black wash, which creates a sealed surface between sand and metal. This is crucial for the release of the piece from the mold post-casting. The black wash is applied using airless spraying technology, which reduces overspray compared to air-assisted systems. The pump can be used on both Styrofoam and sand models to achieve smooth casting surfaces.

Advantages of WIWA Technology:

Reduces overspray significantly
Compatible with various solids content in black wash

Global Presence:

WIWA operates globally with headquarters in Germany and additional locations in the USA, China, and the UAE.
