The DOSATRON D6 IL 2, D6 IL 3000, and D9IL3000 are water-powered proportional dosing pumps designed for precise chemical injection in industrial applications. These units leverage the hydraulic energy of water flow to operate, ensuring consistent dosing ratios without the need for external power sources. Each model is tailored for different dosing ranges and flow conditions, making them versatile solutions for various industrial processes.
The D6 IL 2 is designed for industrial applications requiring controlled chemical consumption with a dosing range from 0.2% to 2%. It operates optimally with a flow range of 100 l/h to 6 m³/h and a pressure range from 0.3 to 8 bar, making it suitable for processes where repeatable dilution is critical. The D6 IL 3000, on the other hand, supports a lower dosing range of 0.03% to 0.3%, catering to applications requiring precise additive metering at relatively low concentration levels. It operates within the same flow range as the D6 IL 2 but with a slightly lower starting pressure of 0.23 bar. The D9IL3000 is tailored for very low dosing ratios from 0.03% to 0.2%, with a broader flow range from 500 l/h to 9 m³/h and a pressure range from 0.15 to 8 bar, making it suitable for centralized installations and low-pressure networks.
For an application involving low-dosage chemical control in centralized industrial installations, such as metalworking or car washing, the D9IL3000 stands out due to its ability to maintain consistent proportioning at very low dosing ratios and across a wide range of operating conditions. Its adjustable stroke volume and integrated by-pass options also provide enhanced control and flexibility. In contrast, the D6 IL 3000 would be preferable for scenarios requiring precise additive metering at low concentrations, whereas the D6 IL 2 is better suited for medium to high dosing ratios in chemical feed and additive blending operations.
| Product | Dosing Range | Flow Range (l/h) | Pressure Range (bar) | Injection Rate (l/h) | Connection Size |
|---|---|---|---|---|---|
| D6 IL 2 | 0.2% to 2% | 100 to 6000 | 0.3 to 8 | 0.2 to 120 | BSPT 1 1/4'' Ø 33 × 42 mm |
| D6 IL 3000 | 0.03% to 0.3% | 100 to 6000 | 0.23 to 8 | 0.03 to 18 | BSPT 1 1/4'' Ø 33 × 42 mm |
| D9IL3000 | 0.03% to 0.2% | 500 to 9000 | 0.15 to 8 | 0.15 to 18 | Ø 40 × 49 mm |
For applications requiring medium to high dosing ratios, the D6 IL 2 is recommended due to its wider dosing range and higher injection capacity. The D6 IL 3000 is suitable for applications needing precise control at lower concentrations. For centralized installations requiring very low dosage ratios, the D9IL3000 is the optimal choice, offering advanced features for consistent and flexible operation.
