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.
Catalog-style construction view of a YW long-shaft under-liquid sewage pump with the motor above the mounting plate. Confirm the exact JIABO immersion depth and drawing before ordering.

Typical applications
Where this series may fit.
Application fit and final model depend on operating conditions. Please confirm with the current technical sheet.
- Sump and tank wastewater transfer
- Industrial effluent and process drainage
- Installations requiring an above-liquid motor
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 hydraulic section pumps liquid while the shaft extends into the sump. - Configuration
Submerged sewage-pump arrangement; confirm immersion depth and mounting. - Liquid suitability
Wastewater; solids passage and chemistry require model confirmation. - Typical use
Industrial sumps and wastewater transfer.
Selection information
What we need to size it.
- Flow and total dynamic head
- Liquid level, sump depth and immersion length
- Solids, fibers, chemistry and temperature
- Mounting plate, discharge pipe, materials 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.
