The Dosatron product range includes models with standard internal injection and models with external injection, designated IE. To most buyers, this looks like a minor configuration option. In some applications...
Dosatron Technology
Water-Powered Dosing Pump
The Original Water-Powered Dosing Technology
Dosatron is the original inventor of the non-electric proportional dosing pump, a technology developed in 1974 and still unmatched today. Autoflo carries the complete Dosatron range in Malaysia, built on the same water-powered mechanism across every line.
Two pistons, one pump. A water-driven hydraulic motor piston moves back and forth under line water pressure alone, and a system of valves reverses its stroke automatically. That motion directly drives a second, mechanically linked dosing piston, which draws in the concentrate on its suction stroke and injects it into the passing water on its discharge stroke. Because both pistons move on the same shaft, the volume of concentrate injected is always a fixed, pre-set fraction of the volume of water flowing through the pump — no electronic flow meter, no controller, and no calibration required.
The result is dosing that is proportional by construction, not by control loop: if the water flow doubles, the dosage doubles with it; if the flow stops, dosing stops instantly. Mixing also happens inside the pump body, so the treated water leaves fully blended and ready to use.
Non-electric — powered entirely by water pressure and flow, ideal for remote sites and off-grid installations across Malaysia's plantations, farms and municipal networks
Purely mechanical proportional dosing — accuracy is built into the piston geometry, not reliant on sensors or software
Adjustable dosing ratio — manually set the dosing piston's stroke length to change the injection percentage, no measuring device needed
Seven dedicated product lines — Animal Health, Green, Water, Industry, Food & Hygiene, Expert and Generic, covering livestock medication through high-flow industrial chemical feed
