Typical applications
Where this series may fit.
Application fit and final model depend on operating conditions. Please confirm with the current technical sheet.
- Pipeline-connected wastewater transfer
- Municipal and commercial drainage systems
- Industrial effluent containing compatible solids and fibers
Technical overview
How this range is used.
These are series-level characteristics, not a performance guarantee for a specific model. Confirm flow, head or pressure, power, dimensions, materials, and operating limits against the current datasheet.
- Operating principle
A centrifugal sewage-pump hydraulic section moves wastewater through a pipe system. - Configuration
Pipeline-connected sewage-pump arrangement; confirm mounting for the model. - Liquid suitability
Wastewater; solids passage and chemistry require model confirmation. - Typical use
Pipeline wastewater transfer and industrial drainage.
Selection information
What we need to size it.
- Flow and total dynamic head
- Solids size, fibers and liquid characteristics
- Pipeline diameter, flange standard and service access
- Power supply, seal and current model curve
Reference specification sheet
Parameters for an international quotation.
These values describe common enquiry formats in Europe and North America—not confirmed ratings for every JIABO model. The quotation and motor nameplate control the final specification.
| Primary duty data | Required flow and total dynamic head, pit or sump geometry, liquid level range and installation arrangement. |
|---|---|
| Wastewater data | Maximum solids size, fiber content, concentration, pH, temperature, abrasiveness and corrosiveness. |
| Electrical reference | Europe: 1 × 220–240 V, 50 Hz (smaller duties) or 3 × 380–415 V, 50 Hz. North America: commonly 3 × 230/460 V, 60 Hz. Confirm the exact motor nameplate before ordering. |
| Construction to specify | Wet or dry installation, discharge size, impeller type, materials, seals and level control. |
| Documents to request | Curve, solids passage, motor data, dimensions and maintenance/access requirements. |
Regional electrical examples are reference conventions supported by published manufacturer data: Grundfos 230/400 V, 50 Hz data ↗ and Franklin Electric 230/460 V, 60 Hz data ↗. Availability must be confirmed for the selected JIABO model.
