High Accuracy Metering Pump | CENTRAC™ B Series

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.

 

  • Material (liquid end): 316SS / PVDF / PVC / PP / Acrylic
