Where this series may fit.
Application fit and final model depend on operating conditions. Please confirm with the current technical sheet.
- Process-liquid transfer
- Electric-drive transfer systems
- Applications needing a diaphragm-pump configuration
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
An electric drive moves diaphragms to draw in and discharge liquid. - Configuration
Electrically driven, positive-displacement diaphragm pump. - Liquid suitability
Process liquids selected against diaphragm, valve, and wetted-part compatibility. - Typical use
Metered or general process transfer where electric drive is available.
Selection information
What we need to size it.
- Liquid composition, viscosity and solids
- Required flow and discharge pressure
- Electrical supply, seal and diaphragm materials
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, discharge pressure and suction condition; describe solids and acceptable pulsation. |
|---|---|
| Drive utility | QBY: available compressed-air pressure and volume. DBY: electrical supply, with regional voltage/frequency confirmed. |
| Electrical reference | For electric-drive DBY enquiries: Europe commonly 220–240 V 1-phase or 380–415 V 3-phase at 50 Hz; North America commonly 230/460 V 3-phase at 60 Hz. |
| Construction to specify | Body, diaphragm, ball, seat and seal materials selected against the actual liquid and cleaning chemicals. |
| Documents to request | Flow versus pressure/air-consumption data, solids limit, connection size, dimensions and approved material combination. |
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.
