  • A Primer on Metering Pumps | Pumps & Systems

    2011-12-17 · Although a metering pump can generally be adjusted to pump at any flow rate between 0 and its maximum capacity, its accuracy is measured over a range determined by the pump's turndown ratio. Most metering pumps have a turndown ratio of 10:1, which means that the pump is within its accuracy rating anywhere between 10 …

    2012-2-21 · When Robert Sheen invented the metering pump in the 1930s, the core of his invention was a method of controlled volume that was inherent to the pump. The metering pump did not depend on a bypass valve after the discharge; speed changes to the pump by replacing belts, pulleys or motors; changes to the pump size to limit the amount of chemical dosed to a specific application of boiler feed or cooling tower chemicals; or the operator diluting the chemicals to match the pump's application rate.
