Dosatron D8R Dosing Pumps



Ideal for horticultural equipment, poultry houses and general farm use, the Dosatron D8RE2 Injector easily dispenses cleaning and sanitizing chemicals. Its large 40 GPM capacity makes it ideal for chemical dispensing, high-volume cleaning and sanitizing. 

Excellent for high-volume centralized systems, the injector is powered by water pressure. The dispenser installs directly in your water supply line and mixes the appropriate amount of solution with water regardless of variations in flow or pressure in your main line.

Operating Principle

Installed directly in the water supply line, the Dosatron operates by using the flow of water as the power source. The water activates the Dosatron, which takes up the required percentage of concentrate directly from the container and injects it into the water. Inside the Dosatron, the concentrate is mixed with the water, and the water pressure forces the solution downstream. The dose of concentrate will be directly proportional to the volume of water entering the Dosatron, regardless of variations in flow or pressure, which may occur in the main line.

Regulations : Refer to local water regulations, prior to installing your Dosatron.
To optimize your Dosatron, we advise to :
- Install a filter (300 mesh [60 microns]) upstream, depending on your water quality.
- Change the dosing seals once a year.
- Rinse as often as possible with clear water.
- Turn off the water supply and allow the pressure to drop to zero before adjusting the injection rate.
- Install necessary protections for excess flow, excess pressure and water hammer (anti-hammer flow/pressure device).
- Install your Dosatron on a total by-pass line.
For all other installation advice, please consult us.
