Comparaison of ATEX-Certified Dosing Pumps for Hazardous Environments
Published on:
October 12 2026
In industrial settings where potentially explosive atmospheres are present, selecting the right dosing pump is crucial for safety and efficiency. The DOSATRON D3IL10EX, D3IL5EX, and D8IL2 EX are ATEX-certified dosing units designed to meet these challenges. Each offers unique capabilities tailored to specific dosing requirements in hazardous environments.
The D3IL10EX, D3IL5EX, and D8IL2 EX dosing units are designed for chemical injection in industries such as surface treatment and mining where ATEX compliance is mandatory. The D3IL10EX offers an injection range of 1–10% and operates with water flow rates from 10 L/h to 3 m³/h, making it suitable for applications requiring higher concentration and flow variability. The D3IL5EX, with an injection range of 0.5–5% and similar flow capabilities, is ideal for moderate dosing needs. The D8IL2 EX is engineered for high flow applications, supporting water flow rates from 500 L/h to 8 m³/h with an injection range of 0.2–2%. This makes the D8IL2 EX optimal for large-scale operations requiring high throughput.
For applications requiring precise dosing in fluctuating flow and pressure conditions, such as in water treatment facilities, the D3IL10EX and D3IL5EX offer significant advantages due to their wide injection ranges and ergonomic dosage adjustment systems. The D3IL10EX, with its higher concentration capacity, is particularly effective where precise high-concentration dosing is necessary. In contrast, the D8IL2 EX excels in scenarios demanding high volume flow and lower concentration injection, such as in large-scale industrial washdown systems where maintaining constant flow is more critical than the exact concentration.
| Model | Injection Range | Water Flow Range | Operating Water Pressure | Concentrated Additive Injection | Stroke Volume |
|---|---|---|---|---|---|
| D3IL10EX | 1 - 10% | 10 l/h - 3 m3/h | 0.50 - 6 bar | 0.1 - 300 l/h | 0.53 l |
| D3IL5EX | 0.5 - 5% | 10 l/h - 3 m3/h | 0.30 - 6 bar | 0.05 - 150 l/h | 0.53 l |
| D8IL2 EX | 0.2 - 2% | 500 l/h - 8 m3/h | 0.15 - 8 bar | 1 - 160 l/h | 1.7 l |
For high precision dosing in environments with variable water flow and pressure, the D3IL10EX is recommended due to its extensive injection range and compatibility with high concentration additives. The D3IL5EX is suitable for moderate dosing applications where a balance of precision and variability is needed. For large-scale operations requiring high water throughput, the D8IL2 EX is optimal. Each of these units ensures compliance with ATEX standards for safety in hazardous environments.
