Milton Roy Centrac Metering Pump
The Centrac? Electronic Variable Speed Metering Pump is specifically engineered to operate with design accuracy over a 100:1 turndown ratio. This allows the CENTRAC? Series to operate accurately and efficiently between 1% and 100% of rated capacity.
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.
This advanced series of metering pump provides significant operating benefits to water and wastewater treatment facilities. Compared to other metering pumps, Centrac provides 10 times the turndown ratio, twice the accuracy, and far greater responsiveness.
