DOSATRON's ATEX-certified non-electrical dosing pumps
DOSATRON offers two ranges of ATEX-certified dosing pumps for zones 0, 1 and 2 in gas-type atmospheres, and 20, 21 and 22 in dust-type atmospheres.
These are the D3IL and D8IL ranges, which allow, without electricity, the on-line dosing of a wide range of additives used in industry, whether liquid or soluble, acid or alkaline, fluid or viscous.
These products can be used for many applications: disinfection, lubrication, surface treatment, remineralisation, dust stabilisation, pH adjustment, etc. They guarantee a high level of precision, regardless of variations in flow rate and pressure in the hydraulic network on which they are installed.
These two ranges operate on networks from 10 to 8,000 I/h. The additives are injected over a dosing range of 0.03% to 10% for the D3IL ranges and 0.03% to 5% for the D8IL ranges.
In ATEX zones, proportional dosing with conventional dosing equipment may be restrictive, as it implies that the entire dosing system, including the flow meter, the pump power supply and possibly the flow control solenoid valves, is ATEX certified.
The choice of a DOSATRON dosing unit therefore simplifies the installation as much as possible while guaranteeing the precision and repeatability of the dosing functionality.
