Dosatron - D132 MegaFlo Injectors - 132 GPM (3 in)

Brand: Dosatron

The Dosatron D132 series delivers water-powered proportional injection at 132 GPM on 3 in mains, part of the MegaFlo line. Each unit runs on water pressure alone and injects concentrate in fixed proportion to incoming water, with no electricity and no batch tanks.

Built for the head of commercial irrigation systems, nurseries, and large controlled-environment facilities, the D132 is offered across several dilution ranges and seal materials to match both the required injection ratio and the chemistry being dosed.

Available Options

• 0.1-1% (1:1000-1:100) 3 in Viton (FKM) Seals [D132MZ1BPVFII]
• 0.1-1% (1:1000-1:100) 3 in Kalrez (FFKM) Seals [D132MZ1BPVFKII]
• 0.02-0.2% (1:5000-1:500) 3 in Aflas Seals [D132MZ5000BPAFII]
• 0.003-0.03% (1:30000-1:3000) 3 in Kalrez (FFKM) Seals [D132MZ30000BPVFKII]

Key Features

• Water-powered proportional dosing, no electricity
• 3 in NPT connection; 132 GPM flow rate
• Built-in bypass (BP) for clear-water flushing
• Dilution ranges from 1:30000 up to 1:100
• Seal options in Viton, Aflas, and Kalrez

Choosing Your Model

Models differ by dilution range and seal material. The dilution range (percentage and ratio) sets how much concentrate is injected per unit of water. 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; and Kalrez (FFKM) for peracetic acid and strong oxidizers such as ZeroTol and SaniDate.

Ideal Applications

• Head-of-system commercial fertigation
• Nursery and field irrigation mains
• Large controlled-environment facilities
• Peracetic-acid and oxidizer injection (Kalrez)
