Dosatron® D128R Medicator
Product Overview
Chemical injection failures during peak growing cycles can lead to catastrophic crop loss, uneven nutrient distribution, and expensive system shutdowns. When your fertigation equipment fails during the height of the season, the time pressure to restore precise dosing is immense. With supply chains often fluctuating and lead times extending for critical components, maintaining a reliable inventory of dosing pumps is essential. Securing your Dosatron units now ensures your clients do not face the risks of stunted growth or chemical waste during high demand periods. Proper planning today prevents the frantic search for replacements when the summer heat is at its peak and the margin for error is zero.
The Dosatron D128R Medicator offers a distinct technical advantage over venturi injectors or low grade electric pumps by operating strictly on water pressure with no electricity required. This volumetric design ensures that the chemical concentrated is injected in direct proportion to the volume of water entering the system, regardless of fluctuations in flow or pressure. By automating the dosing process with high precision, your crews save hours on manual mixing and calibration while reducing the risk of over-fertilization. Using this industry standard injector provides your business with a competitive edge by delivering consistent results and reducing long term maintenance callbacks on every install.

Installation Notes
Install the D128R on a bypass line with shutoff valves to allow for easy service without interrupting the main water supply. A 200 mesh filter must be installed upstream of the unit to prevent debris from damaging the internal piston. Ensure that the water flow follows the arrow on the body and use Teflon tape on the 3/4 inch NPT connections for a leak free seal. Follow all local plumbing codes regarding backflow prevention when connecting to a potable water source.
