WQB IIB T4
Overview
WQB IIB T4 Flameproof Submersible Pump
Current reference certificate material documents Ex db IIB T4 Gb for selected WQB-series /N models.
Coverage is model-specific and must be matched to the exact model, nameplate and current certificate scope.
Applications
- Projects requiring evaluation of a submersible pump against an IIB, T4 hazardous-area requirement, subject to exact-model certificate verification.
- Selection or replacement cases where the site classification, gas and temperature group, medium and electrical supply can be reviewed together.
Working principle
Certificate evidence establishes the documented marking and scope; it does not establish one family-wide mechanical working principle.
The construction and operating principle must be checked in the technical documentation for the exact selected model.
Features
- Documented marking of Ex db IIB T4 Gb for selected WQB-series /N models.
- Model-specific evidence route based on the exact model, nameplate and current certificate scope.
- Selection process that keeps site classification and local approval requirements explicit.
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 the complete exact-model nameplate information.
- Current certificate scope and the local approval requirements for the destination project.
Verification before selection
Do not extend selected certificate entries to the wider WQB family or claim overseas acceptance. Confirm the exact model, nameplate data and current certificate scope against local approval requirements.
Frequently asked questions
What marking is documented on this IIB page?
The reference certificate material documents Ex db IIB T4 Gb for selected WQB-series /N models.
Does the marking apply to every WQB model?
No. Match the exact model and nameplate to the current certificate scope rather than extending selected entries to the full family.
What project information is needed for verification?
Provide the hazardous-area classification, gas and temperature group, medium, supply, duty point, exact model and local approval requirement.
