About the 220V borehole pump (4SDm3)
The Olbin 4SDm3 single-phase series is a 4-inch submersible borehole pump set supplied as pump + motor with a surface control box for 220 V models. Noryl impellers reduce load and resist corrosion.
Furthermore, stainless-steel wetted parts extend service life. For higher head or long runs, consider the three-phase range; however, for most homes the 220 V set is the practical choice. We stock and support 220V borehole pump sets countrywide.
Installation tip: Measure cable length from the pump in the borehole to the surface control panel. In addition, use a correctly sized 4-core borehole cable, fit a non-return valve above the pump, and keep the unit fully submerged. This single-phase borehole pump is ideal for homes and lodges.

Key benefits of submersible borehole pumps
These features focus on reliability for domestic use.
- 4-inch submersible form factor (fits 4″+ boreholes)
- Noryl thermoplastic impellers (durable, efficient)
- Stainless steel wetted components
- Oil-filled, rewindable motor
Moreover, stainless-steel submersible borehole pump components help extend service intervals.
Applications — single-phase borehole pumps
Typical uses include small holdings and households.
- Household water supply from borehole to storage tank
- Garden and small-plot irrigation
- Pressure boosting for lodges and cottages
For example, this single-phase borehole pump suits homes and small farms.
Sizing a 220V borehole pump
To size correctly, send static water level, drawdown, total pipeline length and diameter, elevation changes, and target outlet pressure. Then, we’ll confirm the duty point and model, and provide the performance curve.
In addition, we can advise on cable gauge and start method where needed. Therefore, you can install with confidence. Ask us to size your 220V borehole pump from your borehole data.
Installation for 4-inch borehole pumps
Follow these practical steps during installation.
- Use a correctly sized 4-core borehole cable rated for current and voltage
- Fit a non-return valve above the pump and keep the pump fully submerged
- Route to a storage tank; use a separate booster set for steady building pressure
Finally, our team can advise on cable gauge for your borehole pump.

FAQ: Which 4-inch submersible is right for my site?
For typical homes, a single-phase borehole pump from the 4SDm3 range is sufficient. For higher head, consider three-phase.
FAQ: Do 220V sets include a control box?
Yes. Every 220V borehole pump set is supplied with a surface control box for protection and wiring.
FAQ: Do you deliver countrywide?
We ship submersible borehole pump sets across South Africa with technical support and spares.
For most homes, a 220V borehole pump is the practical choice; however, higher heads may need three-phase.
