Peristaltic pumps solve critical problem for paint manufacturer

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 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 tbe pumps thereby avoiding the costs, health risks, and environmental issues associated with cleaning solvents.

"It is essential for colour 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."
