Product Overview
The Dosatron D20SVF is a high-capacity, non-electric proportional dosing pump designed to inject precise quantities of liquid concentrate directly into a flowing water line. Powered entirely by water pressure, the pump automatically doses additives with an adjustable ratio from 0.2% to 2%, ensuring reliable and consistent chemical injection without requiring electricity.
Installed inline with the water supply, the Dosatron operates using a hydraulic piston motor driven by water flow. As water moves through the unit, the internal motor activates the dosing piston which draws concentrate from a container and injects it proportionally into the water stream. This proportional dosing system ensures accurate injection regardless of variations in water pressure or flow rate.
The D20 Series is engineered for high-flow installations where dependable chemical dosing is required. Its durable construction, integrated mixing chamber and self-priming suction system make it suitable for industrial processes, water treatment systems, sanitation systems and large irrigation networks.

Frequently Asked Questions
What is the Dosatron D20 Series used for?
The Dosatron D20 Series is a high-flow water-powered proportional dosing pump designed for injecting liquid additives into a water line. It is suitable for larger-scale animal health, agriculture, fertigation, water treatment and chemical dosing applications.
Does the Dosatron D20 need electricity?
No. The D20 operates using water pressure as the power source. Water flow activates the internal motor piston, which draws concentrate into the unit, mixes it with the water, and sends the treated solution downstream.
What flow rate does the Dosatron D20 handle?
The D20 operates from 1 m³/h to 20 m³/h, which is approximately 5 to 100 US GPM.
What pressure range does the D20 operate at?
The operating pressure range is 0.12 to 10 bar, or approximately 2 to 120 PSI.
What dosing ratio is available?
The D20 has an externally adjustable dosing range of 0.2% to 2%, equal to a ratio of 1:500 to 1:50.
What connection size does the Dosatron D20 use?
The D20 uses 2" male BSP or NPT connections, listed as Ø50 x 60mm. It can also be connected to suitable flexible hose with an internal diameter of 50mm using clamps and turning adapters.
What is included with the Dosatron D20?
The D20 package includes 1 Dosatron unit, support legs, 1 suction tube for concentrated additive, 1 strainer, 1 vacuum breaker device with connection, and 1 owner’s manual.
What filtration is required before the D20?
A water filter must be installed upstream of the Dosatron. The manual gives an example of 50 mesh / 300 micron, depending on water quality. Filtration is especially important where water contains sand, particles or impurities, and it is required for warranty validity.
Can the D20 be installed on a bypass?
Yes. The D20 can be installed directly inline or on a bypass, but a bypass installation is recommended. This allows clean water to pass without operating the Dosatron and also makes the unit easier to isolate for servicing.
What maintenance is required?
The injection area should be rinsed after use by drawing clean water through the suction tube. Dosatron recommends routine maintenance once per year, including replacing the dosing seals and suction tube annually to maintain accurate injection.
