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 submerged impeller lifts water from a low point. - Configuration
Compact submersible drainage arrangement. - Liquid suitability
Drainage water; confirm solids and abrasion limits for the exact model. - Typical use
Temporary water removal, sumps, and site drainage.
Selection information
What we need to size it.
- Required flow and discharge height
- Liquid and solids characteristics
- Power supply, hose or pipe connection, and site conditions
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 depth, normal/minimum liquid level and installation type. |
|---|---|
| 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 | Free-standing or guide-rail installation, discharge size, cable length, impeller type, materials and level control. |
| Documents to request | Curve, solids passage, motor current, cable data, dimensions, submergence limit and approved control/protection arrangement. |
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.
