Areas of application
Steimel ATEX pumps are used for a wide variety of applications. Here you will find a list of the various applications.
Painting and coating systems in hazardous areas
In potentially explosive areas such as paint booths or coating lines, ATEX-compliant pumps from Steimel ensure the safe conveyance of flammable media such as solvent-based paints or bitumen emulsions. The pumps guarantee a consistent material flow while protecting against ignition sources – crucial for process-reliable applications.
Chemical and petrochemical production lines
Steimel pumps are used in systems that process highly flammable substances such as solvents, additives or resins. The ATEX-certified models ensure safe and reliable pumping under high temperature and pressure conditions – designed for continuous operation and aggressive media.
Refineries, tank farms and transhipment stations
When loading, unloading and transferring bitumen, oil products or other hazardous substances internally, pumps must meet the highest safety requirements. Steimel ATEX pumps are robust, durable and suitable for use in different zones – ideal for continuous operation in potentially explosive areas.
Electroplating and surface coating in ATEX areas
Inflammable liquids such as pickling agents, solvents or coating resins are often used in electroplating processes and surface treatments. Steimel pumps convey these liquids safely and precisely – even at high viscosities and in aggressive environments. The ATEX design protects both employees and equipment.
