Paints and Pigments
Accurate and repeatable metering of process fluids into dispersion mills is critical in
achieving uniformity from one batch of paint pigments to another.
Because of their ability to provide consistent, reproducible flows at low volumes,
Watson-Marlow Bredel peristaltic pumps were chosen to replace double diaphragm
pumps at BASF's Michigan paint mixing plant. The pumps require minimal set-up
time and maintenance. The sealless design eliminates the need to clean the pumps,
thereby avoiding the costs, health risks, and environmental issues associated with
cleaning solvents. “It is essential for color consistency that flow rates to the mills be
stable and reproducible," says the production manager. "The double diaphragm
pumps we had been using were apt to stall at low flow rates. We no longer have that
problem since we installed the peristaltic pumps.”
