What Needs to Be Confirmed for the Selection of Explosion-Proof Submersible Slurry Pumps?
Explosion-proof submersible slurry pumps are used for slurry transport environments where there may be risks of flammable gases, vapors, or dust. They must not only meet flow rate, head, and wear resistance requirements, but also comply with safety regulations for hazardous areas on site.
Before selection, the following need to be confirmed:
1. Hazardous area classification;
2. Name of flammable gas or dust;
3. Explosion-proof rating;
4. Temperature class;
5. Standards adopted by the project;
6. Destination country and certification requirements;
7. Voltage, frequency, and control method.
At the same time, basic operating conditions of the pump must be provided, including flow rate, head, medium, solid content, particle size, temperature, corrosiveness, submersion depth, and pipeline conditions.
Standard submersible slurry pumps cannot be directly used in explosion-proof areas without confirmation. The installation, wiring, and maintenance of explosion-proof pumps must also not alter the flameproof structure or bypass protective devices without authorization.
When requesting a quote, both operating conditions and explosion-proof requirements should be submitted simultaneously, so that technical personnel can confirm the product structure, applicable rating, and available certification documents.
