EMEC Americas” MF Series microprocessor-controlled metering pump automatically calculates the PPM of required chemical concentration based on the flowrate received from an inline meter. Because the calculation of PPM is not static to flow, the new pump increases critical PPM chemical injection applications by dynamically adjusting the dosing as the flowrate changes. This allows users to correct the amount of chemical needed to meet the application, increasing the safety of the chemicals used as well as saving money by eliminating over dosing. The pump is backed by a five-year diaphragm warranty. It is capable of flowrates from .025 to 15.85 GPH at pressures from 29 to 363 PSI and includes liquid-end options in polymethyl methacrylate, PVDF, and stainless steel.
