Novosystems Farben & Additive GmbH of Seevetal, Germany, said its WB4000 dosing pump is designed to meter out liquid colorant for plastics processing.
It can be fitted with three different pump heads, for injection molding, extrusion or polyurethane processing. A new progressive cavity pump head can be used either for very large capacity, such as coloring for extrusion processes, or for large amounts of color, at high levels of accuracy.
Novosystems also makes the liquid colors.
