SA submersible borehole pumps

The SA catalogue organizes submersible borehole pumps by well diameter, flow range and number of stages. It covers water supply, pressure boosting, irrigation and groundwater lowering, with separate pages and curves for each hydraulic series.
Range technical data
- Power range
- 0.18–22 kW
- Maximum flow
- 54 m³/h
- Maximum head
- 450 m
- Outlets
- 0.5–3 in, by subrange
- Electrical supply
- Up to 3 kW: 1~ 220–240 V or 3~ 380–415 V; above 3 kW and all 6-in models: three-phase only, 50 Hz
These figures describe the catalogue range or stated subrange. Maximum flow and maximum head/pressure are not a single duty point. Select the exact model from its curve and confirm materials, electrical version and connections.

A closer look at the series
SA is a broad borehole family rather than a single hydraulic duty. The range overview separates narrow and larger wells, then directs the reader to the page for each flow series. A model code records well diameter, hydraulic capacity, number of stages and motor power.
The brochure includes single-phase and three-phase supply options for certain ranges, while other ranges are three-phase only. Typical uses include building water supply, pressure boosting, garden and farm irrigation and groundwater lowering. Select a pump by the actual inside diameter of the well, required flow and total head, then check the motor supply and installation requirements for the exact SA model.
Features
- Ranges organized by well diameter
- Multistage model coding
- Separate Q–H pages for each flow series
- Electrical supply varies by range
Applications
- Building water supply
- Garden and farm irrigation
- Groundwater lowering
Materials
The 4SA model description identifies a steel submersible pump, but this brochure does not provide a complete component material schedule or steel grade. Check the series catalogue for the selected configuration.
Operating conditions
Maximum liquid temperature +35 °C. Phase availability is model-specific: the overview lists single-phase and three-phase versions up to 3 kW, with larger powers and 6-inch models three-phase only. The 4-inch pump/motor section lists IP68 and class B insulation.
Construction and application
Before selecting
- Start from the well size, then select the SA subrange and its model curve.
- Match flow and total dynamic head; confirm the outlet connection.
- Check the exact model’s electrical phase and the +35 °C liquid limit.
Your questions
Series questions
Can every SA power rating be supplied single-phase?
No. The overview restricts higher powers and 6-inch models to three-phase supply. Confirm the phase in the exact model row.
How do I choose among SA subranges?
Use the overview to choose the well class and flow range, then read the model curve for the required head. The highest flow and head of the overall range do not describe one model duty point.

Use the range index on page 1 to find the appropriate well class and flow series, then open its referenced performance page. Confirm stage count and the model’s electrical phase.
