The 4SDM3/18 1.5HP Doyin electric submersible pump price in Kenya is KSh 24,999. With a 122m maximum head and up to 4,800 liters per hour, this model is suited to borehole systems that need stronger lifting performance. It is a 4-inch deep-well pump for residential water supply, tank filling, irrigation, and farm use. Doyin lists the 4SDM series for drilled wells, boreholes, ponds, tanks, household supply, and agricultural irrigation.
When More Head Matters
Choosing a borehole pump is not only about horsepower. The required head is just as important.
The 4SDM3/18 can reach a maximum head of 122 meters, giving it a higher lifting range than the smaller models in this series. Its maximum flow is 4.8 m³/h, or about 4,800 liters per hour.
This makes it a good fit when water has to travel from the borehole to an elevated storage tank or across a longer delivery line.

Why Go for the 1.5HP Model?
The main reason to choose the 4SDM3/18 is its 122m maximum head.
If your water point requires greater lifting capacity, stepping up to this 1.5HP model can give your system more headroom. The 4.8 m³/h maximum flow also makes it suitable for regular tank filling and water supply duties.
The pump is designed for vertical installation in a borehole. Doyin specifies IP68 protection and a 4-inch minimum well diameter for the 4SDM series.
