The versatile Dosatron D14MZ2 chemical injector is used in multiple industries, from Irrigation to Metal Processing. It can easily be installed on a boom, cart, or plumbed into a system. For industrial applications, install the D14MZ2 metering pump using an Industrial Plumbing Kit (IPK34-14GPM).
The D14MZ2 has a flow range from 0.05 to 14 GPM and a ratio range of 1:500 to 1:50. It is water-powered, easy to adjust, and accurate regardless of variations in flow and pressure.
How it works:
The Dosatron pulls up solution like a syringe, drawing in the concentrate with the plunger. On the down stroke, the concentrate is displaced into the body of the Dosatron, where it mixes with the incoming water. Then just the right amount of fertilizer is discharged into the water line.
The Dosatron difference:
Dosatron units feature superior engineering to create the most durable, easy-to-use, low-maintenance product on the market. We manage your chemical application through repeatability, regardless of fluctuations in pressure or flow. Dosatron also supports you every step of the way with world-class customer service. Trust only genuine Dosatron products.
