Dosatron - Water Powered 26 GPM Dosers - D6 MidFlo Series

Brand: Dosatron

The Dosatron D6 MidFlo series is a line of water-powered proportional dosing pumps with 1-1/4 in connections, built for medium-flow fertigation and chemical injection at flow rates up to 26 GPM. Each unit runs on water pressure alone with no electricity, drawing and blending concentrate in direct proportion to the water moving through it so the dose stays constant even as flow and pressure vary.

These injectors suit greenhouse benches, irrigation zones, and controlled-environment agriculture where one pump must feed several lines at higher volume than a 3/4 in unit. The series is offered in multiple dilution ranges and seal materials so operators can match the unit to both their target injection rate and the chemistry being dosed.

Choosing Your Model

Models in this series differ on two axes. First, the dilution range (shown as a percentage and a ratio) sets how much concentrate is injected per unit of water: lower ranges like 0.03-0.3 percent (1:3000) are for highly concentrated stock, while higher ranges like 0.2-2 percent (1:500-1:50) deliver more product per gallon. Second, the seal material is matched to your chemistry: Viton (FKM) for neutral to acidic feeds such as fertilizers and pH-down; Aflas for alkaline feeds such as pH-up, liquid lime, and carbonates; High-Temp Aflas for alkaline feeds at elevated temperatures; and Kalrez (FFKM) for peracetic acid and strong oxidizers such as ZeroTol and SaniDate. Choose the dilution range your feed program needs, then the seal that matches the product you are dosing.

Ideal Applications

• Medium-flow greenhouse fertigation
• Multi-line irrigation zones
• Alkaline pH-up and carbonate dosing (Aflas)
• Peracetic-acid sanitizer dosing (Kalrez)
