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 at the design point, plus minimum and maximum operating flow. |
|---|---|
| Suction conditions | Source level, suction pressure, pipe length/diameter and available NPSH information where applicable. |
| 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 | Inline or end-suction layout, casing/impeller material, seal, flange standard and motor enclosure. |
| Documents to request | Performance and efficiency curve, NPSH curve, motor data, dimensions and allowable operating range. |
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.
