CENTRAC B 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.
