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.
In addition, these pumps offer a 100:1 turndown ratio. The advanced design enables the pumps to respond instantly to changes in dosage rate, making it the ideal metering pump for a wide range of flow rates in water and wastewater treatment applications.
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.
