Which Doyin AC Submersible Pump Should You Choose?
The right Doyin pump depends on the water level, required flow, total pumping head, borehole yield, pipework and available power supply. Horsepower alone does not determine whether a pump will work for a particular borehole.
For smaller domestic borehole systems, the 4SDM3 series provides 0.5HP to 2HP options with maximum heads from 50m to 158m.
For higher lifting requirements, the 4SD3 and 4SP5 series provide models with maximum heads reaching 358m.
Where the priority is moving a larger volume of water, the 4SP10 series reaches up to 14,400 litres per hour.
Doyin AC Pump Applications
The Doyin AC submersible pumps can be used for:
- Borehole water supply
- Home and apartment water systems
- Elevated tank filling
- Farm water supply
- Irrigation
- Livestock watering
- Schools and institutions
- Commercial properties
- Large residential developments
Doyin AC Submersible Pump Installation Requirements
Doyin AC submersible pumps can serve boreholes, shallow wells, rivers, reservoirs, tanks and other suitable water sources. Therefore, installation requirements depend on the pump model, water source and intended application.
Before installation, consider the following:
- Water source: First, identify whether the pump will draw water from a borehole, well, river, reservoir, tank or another source. The source must provide enough water for the selected pump.
- Pump positioning: Position the pump correctly and keep it adequately submerged during operation. Also, avoid placing it directly on sediment or debris.
- Electrical supply: Check the pump’s required voltage, phase and power rating, then match them with the available AC power supply.
- Control equipment: Use suitable motor controls and electrical protection for the selected pump and power supply.
- Delivery pipe: Select the pipe size according to the required flow, total head and delivery distance. A suitable pipe helps reduce unnecessary friction losses.
- Submersible cable: Choose a cable with the appropriate size and length for the pump’s power and installation depth.
- Non-return valve: Where required, install a suitable non-return valve to prevent water from flowing back through the delivery line when the pump stops.
- Borehole compatibility: For borehole installations, confirm that the borehole diameter can accommodate the selected pump. For example, applicable 4-inch Doyin models require a compatible borehole diameter.
- Water availability: Check the water source’s yield, particularly when using a shallow well, river intake or other limited water source. The pump should not demand more water than the source can provide.
- Dry-run protection: Where water levels can change, consider appropriate dry-run protection to prevent the pump from operating without sufficient water.
Professional Pump Sizing
Finally, select the pump according to the required flow, total pumping head, water-source conditions, delivery distance, pipework and available electrical supply. This approach provides a more reliable match than choosing a pump based on horsepower alone.
Maximum Head Does Not Equal Pumping Height
A Doyin pump advertised with a 150m or 200m maximum head does not necessarily deliver its maximum flow at that height.
As pumping head increases, the available flow changes. Pipe friction, vertical elevation, water level and the rest of the installation also affect performance.
For this reason, the pumping range shown in the table is useful when comparing models, but the pump should still be selected according to the complete borehole system.
Doyin AC vs Doyin AC/DC Submersible Pumps
A Doyin AC submersible pump is designed for an AC electrical supply, making it suitable for installations using mains electricity or an appropriate generator.
A Doyin AC/DC hybrid pump is a different configuration designed to accommodate both AC and DC power. These pumps are particularly relevant where solar power forms part of the pumping system.
PureFlex stocks both Doyin AC submersible pumps and Doyin hybrid AC/DC pumps, allowing the power source to be considered alongside the pumping requirements.

Which Doyin AC pump is suitable for a deep borehole?
Several Doyin models provide high maximum heads, including the 4SD3/40 at 287m and 4SD3/50 at 358m. The appropriate model depends on the actual dynamic water level, required flow and total pumping head.
Can PureFlex install a Doyin AC submersible pump?
Installation can be offered on request. Installation requirements depend on the borehole and complete pumping system.
How do I choose the right Doyin borehole pump?
Provide the borehole depth, dynamic water level, required water flow, tank height, pipe size and available power supply. These details help determine the appropriate pump specification.
Do Doyin AC pumps work with solar power?
Standard AC Doyin pumps require an appropriate AC power supply. For solar applications, PureFlex also offers Doyin hybrid AC/DC submersible pumps designed for solar and AC power configurations.
