Can Air Diaphragm Pumps Be Used in Explosion-Proof Areas?
The key feature of Eichitwo air diaphragm pumps is their air-driven operation.
Since they do not use an electric motor, there is no risk of explosion caused by sparks.
They can be safely used in hazardous environments where flammable fluids or combustible gases are present.
In conclusion, Eichitwo air diaphragm pumps are suitable for use in explosion-proof areas.
Air diaphragm pumps can also be used for chemicals and solvents.
Eichitwo air diaphragm pumps can be selected with materials that match the pumped fluid.
A wide range of materials is available, including aluminum, stainless steel, PP, and PVDF.
In addition, grounding the pump helps prevent static electricity buildup, further enhancing explosion protection.
Even resin pumps can be properly grounded, ensuring reliable static electricity control.
How to Ground an Air Diaphragm Pump
Eichitwo air diaphragm pumps are equipped with a grounding female thread located below the nameplate.
Please use this point to properly connect the grounding wire.
There is a possibility that static electricity may be generated if an air diaphragm pump is not properly grounded.
The following is an excerpt from the instruction manual.
If the product is operated without installing a grounding wire, static electricity may be generated due to friction at sliding parts or when the transferred liquid flows inside the casing, depending on the type of liquid being pumped. Depending on the characteristics of the transferred liquid or the installation environment (atmosphere and surrounding equipment), this may cause fire or electric shock hazards.
Summary
Air diaphragm pumps offer advantages as pumps for use in explosion-proof areas due to their lightweight, compact design and cost efficiency.
Because they do not use electric motors, they are inherently explosion-proof. By implementing proper grounding as a static electricity countermeasure, they can be operated with even greater safety.
