This design provides:\n<ul data-sourcepos=\"14:5-16:112\">\n<li data-sourcepos=\"14:5-14:58\"><strong>Silent Operation:<\/strong> The water dampens motor noise.<\/li>\n<li data-sourcepos=\"15:5-15:94\"><strong>Self-Priming:<\/strong> No need for manual priming, as the pump is always surrounded by water.<\/li>\n<li data-sourcepos=\"16:5-16:112\"><strong>High Efficiency:<\/strong> Pushes water upwards, which is more efficient for deep water extraction than pulling.<\/li>\n<\/ul>\n<\/li>\n<li data-sourcepos=\"17:1-17:278\"><strong>0.75HP (Horsepower):<\/strong> This is the motor&#8217;s power output, equivalent to approximately 0.55 kW. For a 3-inch pump with 20 impellers, this horsepower is effectively used to maximize the lifting capability rather than the volume of water, making it ideal for deep, narrow wells.<\/li>\n<li data-sourcepos=\"18:1-18:132\"><strong>Voltage:<\/strong> Operates on standard single-phase 220V\/230V AC (50Hz), compatible with typical household electrical systems in Kenya.<\/li>\n<li data-sourcepos=\"19:1-19:294\"><strong>Maximum Head (Vertical Lift):<\/strong> This is the standout feature of the 3SDM220. With 20 impellers, its maximum head is typically in the range of <strong>120 to 130 meters<\/strong>. This makes it one of the most powerful 3-inch pumps in terms of lift, capable of bringing water from very significant depths.<\/li>\n<li data-sourcepos=\"20:1-20:281\"><strong>Rated Flow Rate:<\/strong> As indicated by the &#8220;2&#8221; in the model, the optimal flow rate is around <strong>2 <span class=\"katex\"><span class=\"katex-html\" aria-hidden=\"true\"><span class=\"base\"><span class=\"mord\"><span class=\"mord text\">m<\/span><span class=\"msupsub\"><span class=\"vlist-t\"><span class=\"vlist-r\"><span class=\"vlist\"><span class=\"\"><span class=\"sizing reset-size6 size3 mtight\"><span class=\"mord mtight\">3<\/span><\/span><\/span><\/span><\/span><\/span><\/span><\/span><span class=\"mord\">\/<\/span><span class=\"mord text\"><span class=\"mord\">h<\/span><\/span><\/span><\/span><\/span> (2000 liters per hour or 33 liters per minute)<\/strong>.
