Designed for hydroponic growing systems and drip irrigation applications, the D14MZ2-HY delivers accurate, water-powered nutrient injection without requiring electricity. With an adjustable dosing range of 0.2% to 2% (7.5 to 75 mL/gal), it automatically maintains the selected nutrient concentration as water flow changes, helping growers achieve consistent feeding throughout the irrigation cycle. Its dosing seals are designed for use with neutral and low-pH nutrient solutions, while the integrated bypass allows nutrients to be turned on or off quickly as operating conditions require. The result is reliable nutrient delivery, simplified system management, and improved consistency in crop production.

For the best performance, the D14MZ2-HY should be installed in series as part of a properly configured hydroponic nutrient delivery system. Positioning the injector where water flow is stable helps maintain precise nutrient dosing, while upstream filtration protects internal components from sediment and debris. The included bypass and union fitting make maintenance and servicing easier, allowing the injector to be isolated when needed without disrupting the entire irrigation system. To promote consistent concentrate uptake, nutrient stock tanks should be located close to the injector and connected with appropriately sized suction tubing. A well-planned installation helps ensure accurate nutrient delivery, dependable operation, and healthy crop development throughout the growing season.

 

Every application is different. Flow rates, water quality, chemical compatibility, and installation requirements all impact the best injector configuration.
