Application
Water and wastewater treatment. CENTRAC pumps are ideal for water treatment applications because of their proven accuracy, responsive design, and capability to dose a variety of chemicals over a wide range of flow rates.  These reliable, low maintenance metering pumps provide efficient dosing and reduce chemical costs.
Overview
CENTRAC pumps combine a unique constant stroke length drive mechanism and electronic variable speed drive technology. The unique drive system provides a steady state accuracy of +/- 0.5% over the entire turndown range. This is twice the accuracy of the standard +/- 1% of most metering pumps. Greater accuracy means better control of the treatment process and more efficient chemical usage.
