Comparison of DOSATRON D9IL2, D6 IL 2, and D3IL10 Dosing Pumps
Published on:
October 06 2026
DOSATRON dosing pumps, namely D9IL2, D6 IL 2, and D3IL10, are state-of-the-art water-powered proportional dosing systems designed to provide accurate chemical injection in various industrial settings. Each model offers unique capabilities tailored to specific applications, ensuring that dosing remains consistent and reliable, regardless of variations in water pressure or flow.
The D9IL2 is engineered for centralized industrial dosing where chemical injection must remain proportional to the water flow, making it suitable for industrial processes that require repeatable dosing without an external power supply. It provides an adjustable injection range of 0.2% to 2% with a water flow range from 500 L/h to 9 m³/h and operates at pressures from 0.15 to 8 bar. The D6 IL 2 is designed for accurate and homogeneous additive injection directly into a water line, ideal for processes where repeatable dilution is critical. It offers a dosing range of 0.2% to 2% with a flow range from 100 l/h to 6 m3/h and pressures from 0.3 to 8 bar. Meanwhile, the D3IL10 caters to metalworking coolant preparation, providing reliable dosing of soluble cutting oil and other additives. It features a broader dosing range of 1% to 10% and operates within a flow range of 10 l/h to 3 m³/h at pressures from 0.5 to 6 bar.
Focusing on an application like metalworking coolant preparation, the D3IL10 stands out due to its specific design for dosing soluble cutting oils, featuring a dosing range of 1% to 10% and a stroke volume of approximately 0.53 liters. Its compatibility with soluble cutting oils and plug-and-play installation make it particularly advantageous for machining-focused tasks. In contrast, the D9IL2 and D6 IL 2, while versatile, are more suited for broader industrial dosing applications and may not offer the same level of specialization for metalworking as the D3IL10.
| Feature | D9IL2 | D6 IL 2 | D3IL10 |
|---|---|---|---|
| Injection Range | 0.2-2% | 0.2-2% | 1-10% |
| Water Flow Range (Min) | 500 L/h | 100 L/h | 10 L/h |
| Water Flow Range (Max) | 9 m³/h | 6 m³/h | 3 m³/h |
| Operating Pressure (Min) | 0.15 bar | 0.3 bar | 0.5 bar |
| Operating Pressure (Max) | 8 bar | 8 bar | 6 bar |
| Concentrated Additive Injection (Max) | 180 L/h | 120 L/h | 300 L/h |
In conclusion, the DOSATRON D9IL2 is best suited for centralized industrial dosing applications requiring a broad water flow range and flexible pressure conditions. For chemical feed and additive blending operations requiring precise dilution, the D6 IL 2 proves to be an excellent choice. Meanwhile, the D3IL10 is specifically recommended for metalworking coolant preparation due to its specialized features.
