Dosatron Hi-Flo Injector - 1-1/2in - 40gpm - 0.03% to 0.20% - Viton Seals

Non-Electric Proportional Chemical Injection, 40 GPM

A Dosatron D40MZ2 Hi-Flo injector delivers accurate proportional chemical dosing at up to 40 GPM through a 1-1/2in connection, powered entirely by water pressure rather than electricity. It holds consistent injection across the 0.03% to 0.20% ratio range regardless of flow or pressure fluctuations in the supply line.

Viton seals extend that reliability to acidic chemistries and soluble cutting oils, and the injector ships as a complete kit — mounting bracket, suction hose, weighted strainer, and quick start guide all included — ready for boom, cart, or inline installation.

Key Features & Benefits

• 2.2 to 40 GPM flow range — performs accurately across the flow rates this connection size is built for.
• 1-1/2in connection — installs directly onto standard water supply lines for boom, cart, or inline use.
• Non-electric operation — water-pressure driven, requiring no electrical supply for reliable chemical delivery.
• Viton seals — built for acidic chemistries and compatible with all soluble cutting oils.
• 0.03% to 0.20% injection ratio — covers most fertilization, sanitation, and treatment programs (7.5 to 75 mL/gal).
• Complete installation kit — includes mounting bracket, suction hose, weighted strainer, and quick start guide.

Who Should Use This

Greenhouse growers, nurseries, and irrigation professionals who need dependable proportional chemical injection for fertilization, sanitation, or crop-protection programs are the direct fit for this injector.

About Dosatron

Dosatron International pioneered water-powered, non-electric proportional dosing pump technology starting in 1974, headquartered in Tresses, France, with a North American base in Clearwater, Florida serving the region for more than 30 years. Its non-electric injectors hold dosing accuracy steady across pressure swings, without drawing power.

Frequently Asked Questions

What is the maximum operating pressure for this injector?

The D40MZ2 Hi-Flo operates within 4.3 to 116 PSI and supports water temperatures up to 104°F. Staying inside that range is what keeps dosing accuracy consistent.

What injection ratio range does this model provide?

The ratio range is 0.03% to 0.20%, with an injection range of 7.5 to 75 mL per gallon. That range covers most fertilizer and chemical treatment programs without changing injectors.

How is this injector mounted?

The D40MZ2 Hi-Flo installs via boom mount, cart mount, or direct inline plumbing using its standard 1-1/2in fitting. Choose whichever matches your existing irrigation setup.

What accessories come included with the injector?

A mounting bracket, suction hose, weighted strainer, and quick start guide ship with every unit. That is everything needed for a first installation without separately sourcing hardware.
