3. Specifications Dosatron – D25 AquaBlend Flow Range
0.05 – 11 GPM 10 – 2500 L/H
Pressure Range
4.3 – 85 PSI 0.3 – 6 BAR
5 – 90 PSI 0.34 – 6.2 BAR
Injection Range
500:1 – 50:1 0.2% - 2%
100:1 – 20:1 1% - 5%
200:1 – 20:1 0.5% - 5%
AquaBlend 5% has a larger injection range than the Dosatron 5%. This make the unit more accurate at the popular 1% setting.

4. Lower End Service Tools Required No Tools Required LOWER END SCREWS
Dosatron
AquaBlend
Use a screw driver to remove the (4) screws holding the lower end
Remove the lower end by turning counter-clockwise
Why is this important?
Maintenance on the AquaBlend is easier. No tools are required when working on the AquaBlend

5. Dosatron shaft cannot be removed
Service and Repairs
Dosatron
AquaBlend
Plunger Shaft cannot be removed
Plunger shaft can be removed with a ¼ turn
Why is this important?
Maintenance on the AquaBlend is easier. The plunger seal is the most common wear item. For the D25, you can only replace the plunger seal by removing it from the shaft

6. Entire shaft can be removed and replaced on the AquaBlend
Converting from 2% to 5%

Why is this important?
Modularity. Pumps can changed from a 2% unit to a 5% unit simply by buying a kit, not an entire new unit. This saves money, and reduces inventory.

7. Motor Piston Design Screws on Dosatron motor sealed with O-rings
AquaBlend
(4) Screws on the piston are sealed with o-rings
Screws on the piston go into blind holes
Why is this important?
Improved performance at low flows. The use of thru holes and o-rings on the D25 creates a path for leaks. The AquaBlend cannot leak because the screw holes do not go thru the piston. This is critical in the first few days of a new flock.

Blind holes on AquaBlend no O-rings required

8. Dosatron arm not guided

AquaBlend
Poppet arm is not guided
Poppet arm is guided
Why is this important?
Improved performance at low flows and increased life. By guiding the poppet arm, it is easier to seat on the chamfer. The reduced movement of the arm means the seal has less side to side movement, which reduces wear on the seal.

9. Motor Piston Design Dosatron springs on tight spring rails
AquaBlend
Tight unsmoothed spring rails
Specifically engineered spring rails
Why is this important?
Improved performance at low flows and spring life. By specifically engineering the spring rails, Hydro Systems has reduced friction and wear on the springs. The reduced friction of the arm means springs last longer.
