Dosatron D14MZ2 14 GPM Chemical Metering Pump (Viton Seals, 0.2–2%) For Sale

The Dosatron D14MZ2VFDII is a water‑powered, proportional chemical metering pump that delivers precise dosing (0.2 %–2 % dilution) without the need for electricity. Flow variations and pressure changes do not affect dosage accuracy. Built with Viton seals for chemical resistance and a three-quarter-inch NPT connection, it is available in polypropylene (blue) or PVDF (white) housing depending on the chemical compatibility required 

No tipping or suction tips required—simply set the ratio and let it run. Installation includes mounting bracket, suction hose with weight, strainer, and instruction manual. Optional bypass and industrial plumbing kits are available for advanced configurations

• Accurate, Non‑Electric Dosing – Delivers exact chemical quantity regardless of flow or pressure changes 

• Broad Dilution Range – Adjustable from 1:500 to 1:50, ideal for low to medium concentration applications 

• Chemical Compatibility – Viton seals and optional PVDF body enable use with hydrofluoric acids, alkaline cleaners, and specialty fluids (e.g., pesticides,

• Easy Installation & Maintenance – Simple mounting, no calibration required, optional bypass mode, and field-serviceable internal seals 

• Reliable Build – Designed for long-term continuous use in industrial or agricultural settings (ISO‑certified manufacturing standards) 

📌 Applications

• Agricultural fertigation and foliar sprays

• Pressure washing and vehicle detailing

• Industrial chemical processing and sanitizing

• Livestock water treatment and hydration systems

• Hydroponics, greenhouses, and horticultural dosing

🔩 What You May Need Extras For

• For bypass or rinse operations: consider the IPK34‑14 GPM industrial plumbing kit (ball valves, regulator, flow restrictor, filter) 

• For FDA-compliant or abrasive chemistries: choose the PVDF housing version (white) instead of standard polypropylene.

• For high‑pressure fluid sources: use a pressure regulator and 200‑mesh filter upstream.
