WQB IIC T4
Overview
WQB IIC T4 Flameproof Submersible Pump
Current reference certificate material documents Ex db IIC T4 Gb for selected WQB-series /N models.
The IIC marking is model-specific; it is not universal across WQB pumps and does not by itself establish a separate mechanical design.
Applications
- Projects requiring exact-model review against an IIC, T4 hazardous-area requirement.
- Selection or replacement cases where site classification, gas and temperature group, medium, supply and local approval can be verified together.
Working principle
The certificate material establishes marking and scope for listed models, not a distinct family-wide mechanical working principle.
Use the exact-model technical documentation to verify construction and operating principle; the IIC marking alone is not evidence of a separate mechanical design.
Features
- Documented marking of Ex db IIC T4 Gb for selected WQB-series /N models.
- Exact-model evidence route using the nameplate and current certificate scope.
- A representative image supports identification only and does not prove the marking on a selected unit.
Selection inputs
- Hazardous-area classification and the required gas and temperature group.
- Medium details, ambient conditions and required flow, head and power.
- Supply voltage and frequency plus complete exact-model nameplate information.
- Current certificate scope and local approval requirements for the destination project.
Verification before selection
The IIC marking is not universal and is not proof of a separate mechanical design. A representative image does not prove certificate marking; confirm the exact model, nameplate and current certificate scope.
Frequently asked questions
What marking is documented on this IIC page?
The reference certificate material documents Ex db IIC T4 Gb for selected WQB-series /N models.
Does IIC identify a separate pump design for every model?
No. The marking is not universal and does not by itself prove a separate mechanical design. Verify the exact model documentation.
Can a representative product image prove IIC marking?
No. Use the exact unit nameplate and current certificate scope; a representative image does not prove the marking.
