Centrifugal pumps

Operating as recirculation pumps, they transport the mixture of chips and cooling lubricant to the filter/separator. They then supply the machines with the cleaned cooling lubricant again. Thanks to their solid and robust design, KNOLL cooling lubricant pumps are extremely reliable and have a long service life.
