Doyin 4SDS7-1100W (1.5HP) AC/DC Hybrid Borehole Submersible Pump

The Doyin 4SDS7-1100W AD is a 1.5HP AC/DC hybrid submersible borehole pump that combines a high-volume output of 7,000 litres per hour with a 95-metre maximum head — a notable step up from the 800W model in both depth capacity and operational range. Designed for estates, farms, schools, and hotels, it runs on both solar and grid power to deliver consistent, bulk water supply around the clock without dependence on a single energy source.

Key Features & Benefits

• 7,000 L/h High-Volume Output — Delivers exceptional flow for a 1.5HP pump, ensuring fast tank filling and steady supply for high-demand installations
• 95M Maximum Head — Extends reach into medium-to-deep boreholes while maintaining full flow rate, covering the majority of residential and commercial borehole depths
• True AC/DC Hybrid Operation — Automatically adapts between solar DC and AC grid or generator power, eliminating supply gaps caused by power outages or low solar conditions
• 1.5HP Brushless Motor — Efficient, low-heat operation that reduces energy consumption and extends the motor’s working life under continuous use
• Stainless Steel Construction — Premium corrosion-resistant body built for sustained submersible operation in borehole conditions
• Solar Panel Compatible — Works with a 3-panel or larger array, making it a practical and affordable solar pumping solution for homes and small commercial operations
• Low Maintenance Requirements — Robust build keeps servicing intervals minimal, reducing operational downtime and long-term costs

Why Choose the Doyin 4SDS7-1100W AD?

• Significant upgrade over the 800W model — deeper reach at 95M head with the same exceptional 7,000 L/h flow rate
• AC/DC hybrid technology means your water supply is never at the mercy of a single power source
• One of the most flow-efficient pumps in the 1.5HP category — delivering more litres per watt than many comparable models
• Trusted Doyin stainless steel build quality tested for long-term reliability in East African borehole conditions
• Well-suited for properties upgrading from a lower-capacity pump without changing pipework or borehole infrastructure
• Compatible with HDPE/PPR piping and non-return valve (NRV) for a clean, professional installation

Applications

Residential Estates and Apartments — Provides high-volume water delivery for large homes and multi-unit developments drawing from medium-depth boreholes.

Hotels and Guesthouses — Ensures consistent water supply for hospitality operations with peak-hour demand and no tolerance for supply interruptions.

Schools and Institutions — Meets the bulk water needs of learning institutions, clinics, and community centres with reliable high-flow delivery.

Agricultural Irrigation — Efficiently feeds irrigation lines and water distribution systems for mid-size farms and horticulture operations.

Livestock Farming — Maintains continuous water supply for cattle, dairy, and poultry operations, including in areas with unreliable grid power.

Off-Grid and Solar Water Systems — A strong choice for hybrid solar installations where both high volume and medium borehole depth are required without sacrificing energy flexibility.
