YW Sewage Pump
Vertical long-shaft under-liquid sewage pumps for sumps and tanks, keeping the motor above the liquid while the hydraulic end operates below the mounting plate.
This photograph shows a configuration in the YW range. The file does not identify an exact model number, so appearance and specifications must be confirmed before ordering.

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.
