The D14MZ5 is a water-powered dosing injector designed to deliver precise chemical dilution without the need for electricity. Its proportional dosing technology automatically adjusts concentrate injection based on water flow, maintaining a consistent dilution rate from 0.5% to 5% (1:200 to 1:20) across a wide range of operating conditions. This dependable performance helps reduce chemical waste, improve application accuracy, and ensure repeatable results in irrigation, sanitation, industrial cleaning, and water treatment processes. The simple mechanical design also minimizes maintenance requirements while providing long-term reliability.

To maximize dosing performance and extend equipment life, the D14MZ5 should be installed in a properly designed water line with adequate filtration upstream of the injector. A 200-mesh (80-micron) filter is recommended to protect internal components from debris, while a downstream check valve helps safeguard the system from water hammer and backflow. Locating the concentrate tank near the injector, using appropriate suction tubing, and ensuring stable operating pressure all contribute to accurate chemical injection and dependable operation. Proper system design and routine maintenance will help the injector deliver consistent results for years of service.
Every application is different. Flow rates, water quality, chemical compatibility, and installation requirements all impact the best injector configuration.
