-Low maintenance

Specification
-Capacity range between 0.45 gph minimum to 550 gph maximum
-Discharge pressures up to 9,000 psi (CENTRAC S), 1,575 psi (CENTRAC B)
-Maximum stroking speed at 162 spm
-± 0.5% steady state accuracy over 100:1 turndown ratio
-Simplex or duplex configurations

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.
