4.5 m³ 140m Doyin 1.5HP Stainless Steel DC Solar Borehole Pump System Kit 4SPS4.5-1100W

The 4.5m³/h 140m Doyin 1.5HP Stainless Steel DC Solar Borehole Pump System Kit 4SPS4.5-1100W is a higher-head solar-powered water-pumping solution for boreholes requiring substantial water lift.

The system combines a Doyin 1.5HP stainless steel DC borehole pump with three 590W solar panels, providing a total PV array capacity of 1.77kWp. It delivers a maximum flow rate of 4.5m³/h and a maximum head of 140 metres, making it particularly relevant for deeper-water applications, elevated tank filling, livestock watering and appropriately sized small-scale irrigation.

The kit also includes 150 metres of 2.5mm² 4-core submersible cable, 20 metres of 6mm² PV cable and one cable-splicing kit. The longer 150m submersible cable complements this higher-head configuration by providing substantial cable length for site-specific borehole installations.

Actual water output depends on borehole yield, total pumping head, pipe diameter, delivery distance, solar conditions and installation quality. Maximum flow and maximum head represent different operating points and should not be expected simultaneously.

• 🚜 Small-Scale Farm Irrigation – can support appropriately sized irrigation systems based on required flow, pressure and total pumping head.
• 🐄 Livestock Watering – useful for supplying storage tanks and livestock watering points from borehole sources.
• 💧 Higher-Lift Tank Filling – the 140m maximum head makes this model particularly relevant where substantial vertical lift is required.
• 🌱 Gardens, Nurseries & Greenhouses – suitable where the site’s water requirements match the available pump performance.
• ☀️ Off-Grid Water Supply – powered by a 1.77kWp solar array for locations with adequate sunlight and limited grid access.

Installation Notes

A professional borehole assessment is recommended before installing the Doyin 4SPS4.5-1100W. The assessment should confirm borehole depth, static and dynamic water levels, borehole yield, required delivery height, pipe diameter, delivery distance and expected daily water demand.

The pump has a specified maximum head of 140 metres. This figure should not automatically be treated as the recommended installation depth. A separate recommended depth range was not supplied for this kit.

Final pump suitability should be determined using total dynamic head. This includes the vertical pumping lift, elevation of the storage tank or delivery point and friction losses through the pipework, fittings and valves.

The three supplied solar panels provide:

590W × 3 = 1,770W = 1.77kWp

The solar panels should be positioned in an unshaded location with suitable orientation and secure mounting to support effective solar operation.

The supplied 150m of 2.5mm² 4-core submersible cable should be installed and supported appropriately within the borehole. The submerged electrical connection should be completed using the supplied splicing kit and appropriate waterproofing procedures.

The 20m of 6mm² PV cable should be routed and protected appropriately between the solar array and pumping system.

Installation scope and any additional components required for the individual site should be confirmed in the final Macire quotation.

Care & Maintenance

• Keep all three solar panels clean and free from dust, leaves and bird droppings.
• Periodically inspect the solar-panel mounting structure and electrical connections.
• Protect the 150m submersible cable and 20m PV cable from physical damage.
• Inspect accessible cable connections and protection components periodically.
• Check delivery pipes, joints, valves and fittings for leaks.
• Avoid operating the pump where the borehole water level could fall below the safe pumping level.
• Monitor water output for unexpected reductions in performance.
• Inspect storage tanks, float valves and delivery pipework regularly.
• Have electrical faults or reduced pumping performance checked by a qualified technician.
• Follow Doyin operating and maintenance instructions for the 4SPS4.5-1100W.

Mini FAQ

What is the maximum flow rate of this Doyin pump?

The 4SPS4.5-1100W has a maximum flow rate of 4.5m³/h. Actual output depends on total pumping head, borehole conditions, pipework and available solar energy.

What is the maximum head?

The pump has a maximum head of 140 metres. Maximum head and maximum flow occur at different operating points and should not be expected simultaneously.

Does the 140m maximum head mean the pump can be installed 140m deep?

Not automatically. Maximum head is different from recommended installation depth. The correct installation depth should be determined from borehole water levels, borehole yield, delivery elevation and total dynamic head.

What power is the pump?

The kit uses a Doyin 1.5HP DC solar borehole pump, model 4SPS4.5-1100W.

Is the pump stainless steel?

Yes. This kit is specifically configured around a stainless steel Doyin borehole pump.

How many solar panels are included?

The kit includes three 590W solar panels.

What is the total solar-array capacity?

The three panels provide:

3 × 590W = 1,770W or 1.77kWp.

What cables are included?

The kit includes 150m of 2.5mm² 4-core submersible cable and 20m of 6mm² PV cable.

Does the kit include a cable-splicing kit?

Yes. One cable-splicing kit is included.

Can this pump fill an elevated water tank?

Yes, provided the combined borehole lift, tank elevation, delivery distance and pipe friction remain within the pump’s operating capability.

Is it suitable for irrigation?

It can support appropriately sized small-scale irrigation where the required flow and pressure are within the pump’s available performance. A site assessment is recommended for correct sizing.
