What flow rate and injection range does the D14MZ3000 operate at?
The D14MZ3000 operates at up to 14 GPM, with an injection ratio range of 1:3000 to 1:333.
How does the D14MZ3000 work mechanically?
It's a water-driven piston — no electricity required. Water pressure activates flow through the unit, which drives a piston that proportionately doses solution for every gallon that passes through. A check valve at the bottom displaces the solution downstream as it mixes into the water source.
What's the difference between this and the Hobby Cultivator?
This is a full commercial-grade unit built from polypropylene for better chemical resistance, with adjustable injection ranges, a bypass switch, and fully replaceable internal and external parts — versus the Hobby Cultivator's single fixed rate and consumable design.
Can units be run in parallel to increase flow rate?
Yes. Running two units of the same model in parallel doubles the flow rate while injecting the same chemistry at the same rate — both units must inject the same nutrient part at the same setting.
