DOYIN 4SDS5-1100W (1.5HP) DC Submersible Solar Water Pump – 80m Head

Solar Water Pump DOYIN 4SDS5-1100W (1.5HP) DC Submersible Solar Water Pump — 120m Head, 5.0m³/h Flow Rate

The DOYIN 4SDS5-1100W is a powerful DC submersible solar water pump designed for demanding water extraction applications where grid electricity is unreliable, expensive, or simply unavailable. With a maximum head of 120 metres and a strong flow rate, it’s built to serve agricultural, residential, and commercial water supply systems that need consistent, dependable performance day after day. As one of the more compact and energy-efficient models in the DOYIN 4SDS5 range, it’s a practical entry point for Kenyan households and small-to-medium farms with moderately deep boreholes who don’t need the higher-power (and higher-cost) 2HP, 3HP, or 4HP versions.

Specifications

Key Features & Benefits

• High Head Performance — Pumps water up to 120 metres, making it suitable for deep boreholes and wells without requiring the largest motor configuration in the range. For most residential and small commercial boreholes in Kenya, this head rating comfortably covers the water table depth found in many regions.
• Efficient Water Delivery — A flow rate of up to 5.0 m³/h (5,000 litres per hour) is more than enough for household consumption, moderate irrigation, and livestock watering, filling storage tanks quickly during daylight hours.
• Solar-Powered Operation — By running on DC power from a solar panel array, the pump eliminates dependence on grid electricity or diesel generators, meaning your ongoing water-pumping costs are limited to occasional maintenance rather than fuel or power bills.
• Robust Stainless Steel Construction — The pump body resists corrosion from borehole water, which often contains dissolved minerals that quickly wear down cheaper materials — helping the pump deliver years of reliable service.
• Optimized Motor Design (3 × 550W) — The three-motor configuration is tuned to make efficient use of available solar input, converting sunlight into consistent pumping output even as irradiance varies through the day.
• Low Maintenance Requirements — With no fuel system or combustion components, this pump needs far less routine servicing than diesel or petrol-powered alternatives — a real advantage for installations in remote areas.

Why Choose the 4SDS5-1100W?

This model offers a strong, cost-effective combination of flow rate and lifting capacity for boreholes that don’t require extreme depth performance. It’s an ideal choice where the recommended depth range of up to 99 metres matches your borehole’s test pumping report, letting you avoid paying for lifting capacity you don’t need. The stainless steel construction and energy-efficient motor design mean lower running costs and a longer service life, while still delivering dependable performance for agricultural, residential, and commercial water needs.

Applications

• Agricultural Irrigation — Delivers water for crops, orchards, and irrigation networks, supporting consistent crop watering schedules.
• Livestock Watering — Provides a reliable water source for farms and animal husbandry operations, even in areas without grid power.
• Residential Water Supply — Supplies water from deep wells and boreholes directly to homes, reducing dependence on water trucking or unreliable municipal supply.
• Commercial Facilities — Supports water transfer and supply requirements for lodges, schools, and other commercial environments.
• Remote & Off-Grid Installations — Purpose-built for locations powered entirely by solar energy systems, where reliability and low maintenance matter most.

Sizing and Installation

Matching this pump to the right solar panel array depends on your borehole’s depth, recharge rate, and daily water demand. Rhema Solar Energy Solutions Limited supplies, delivers, and installs the DOYIN 4SDS5-1100W across Kenya, with guidance on sizing your solar panels correctly to the pump’s 1100W rating for consistent year-round performance.
