Description

The 11kW AC/DC hybrid submersible pump is a heavy-duty borehole water pump built for large farms, irrigation projects, institutions, estates, commercial properties and high-volume water supply systems.

It combines an 11kW motor, maximum flow rate of 36m³/h, maximum head of 210 metres and a large 3-inch outlet. The hybrid system can operate from solar DC power and compatible three-phase AC electricity, giving users more flexibility than a standard AC-only borehole pump.

An exact matching pump family is available under models such as 6iSC36-210-380/550-11000-A/D and 6HJSC36-210-380/520-11000-A/D. Published specifications confirm 11,000W power, 36m³/h maximum flow, 210m maximum head and a 3-inch outlet.

Massive 36,000 Litres Per Hour Flow Rate

The main advantage of this 11kW pump is its high water-moving capacity.

Maximum flow is:

36m³/h

This equals:

36,000 litres per hour

or approximately:

600 litres per minute.

This makes the pump suitable for projects where a normal 2HP, 3HP or 4HP borehole pump cannot provide enough water.

Maximum Theoretical Water Output

Running Time	Maximum Water Output
30 Minutes	18,000 L
1 Hour	36,000 L
2 Hours	72,000 L
4 Hours	144,000 L
6 Hours	216,000 L
8 Hours	288,000 L
10 Hours	360,000 L

These are theoretical figures at the maximum-flow end of the pump curve. Actual water production depends heavily on operating head.

210 Metres Maximum Head

The pump can generate a maximum head of 210 metres.

This gives it the pressure needed for demanding water projects involving deep pumping levels, elevated storage tanks or long delivery lines.

It can be suitable for:

• Deep boreholes
• Elevated tanks
• Hilly farms
• Large irrigation systems
• Commercial water distribution
• Long-distance water transfer

The exact 11kW 6iSC36 model is rated at 210m maximum head.

Actual Flow at Different Heads

One major advantage of finding the exact matching pump family is that published performance data shows how flow changes as head increases.

For the 11kW 36m³/h, 210m model, approximate performance is:

Pumping Head	Approx. Flow
1m	36.00m³/h
29m	29.14m³/h
57m	22.28m³/h
85m	15.42m³/h
99m	11.99m³/h
113m	9.56m³/h
127m	7.13m³/h
141m	5.70m³/h
155m	4.27m³/h
169m	2.84m³/h
183m	1.41m³/h
210m	Near Shut-Off

This performance curve is important because it shows that 36m³/h and 210m are not achieved at the same time. Flow falls as the pumping head increases.

Do Not Size the Pump Using Maximum Head Alone

A 210m maximum head does not automatically mean the pump should be installed in a 210m borehole.

The correct measurement is Total Dynamic Head, commonly called TDH.

TDH includes:

Dynamic water level + vertical lift + pipe friction + fitting losses + required outlet pressure

For example:

System Requirement	Head
Dynamic Water Level	90m
Tank Elevation	15m
Pipe/Fitting Loss	8m
Total Dynamic Head	113m

At approximately 113m head, the published curve for the matching 11kW pump shows around 9.56m³/h, not 36m³/h.

This is why a pump curve should always be checked before buying a large borehole pump.

Powerful 11kW Motor

The motor is rated at:

11,000 watts

or:

11kW

This is approximately 15 horsepower.

It is considerably larger than ordinary domestic borehole pumps.

An 11kW pump is designed for applications where large volumes of water must be moved regularly.

High-Speed 4000rpm Design

A comparable exact-spec 11kW AC/DC pump currently listed in Kenya operates at approximately 4000rpm.

This high-speed design helps the multistage pump generate the pressure required for deep-water lifting.

The motor and pump stages work together to provide the required combination of head and flow.

AC/DC Hybrid Operation

The AC/DC hybrid design is one of the biggest benefits of this pump.

It can operate using compatible:

• Solar DC power
• Three-phase AC grid electricity
• Properly sized three-phase generator supply

Hybrid borehole systems allow farms and commercial projects to use solar energy during sunny hours while retaining AC electricity as an alternative power source.

Hybrid submersible pumps used in Kenya are commonly designed to work from solar, grid or generator power.

380V AC Operation

The exact matching 11kW model uses approximately:

380V AC

This is a three-phase supply rather than ordinary 240V domestic single-phase electricity.

This is important during installation.

Do not connect this pump directly to an ordinary household socket.

High-Voltage DC Solar Input

Matching versions use approximately:

DC 520V or DC 550V

depending on the controller and pump version.

The recommended DC operating range on published models is approximately:

520V to 650V DC.

Because this is a high-voltage solar system, panel string design and electrical protection should be handled by a qualified solar pump installer.

Hybrid Solar Pump Controller

A large AC/DC pump requires a compatible controller to manage the power supplied to the motor.

The controller helps convert and regulate solar power so the pump can operate as solar conditions change.

Depending on the exact controller, functions can include:

• MPPT solar tracking
• Soft starting
• Dry-run protection
• Overload protection
• Overcurrent protection
• Overvoltage protection
• Undervoltage protection
• Phase protection
• Automatic restart
• Tank-level control

The exact protection functions must be confirmed from the controller supplied with the pump.

Solar Panel Capacity

Published data for the matching pump family recommends solar-array power of at least:

1.3 × pump power.

For an 11kW pump:

11kW × 1.3 = approximately 14.3kWp

This means the solar array should be around 14.3kWp or greater, subject to the controller manufacturer’s design requirements.

Example Using 550W Solar Panels

A practical starting calculation would be:

14,300W ÷ 550W = 26 panels

Therefore, approximately:

26 × 550W = 14.3kWp

may provide the required nominal panel capacity.

However, panel quantity alone is not enough.

The installer must also calculate:

• Panel Voc
• Panel Vmp
• Controller MPPT voltage
• Maximum DC input voltage
• Series string length
• Parallel strings
• Temperature correction
• Maximum current

Never connect 26 panels without first designing the correct string configuration.

3-Inch Outlet

The pump has a large:

3-inch discharge outlet.

The exact matching 11kW, 36m³/h, 210m models confirm this 3-inch connection.

The larger outlet is appropriate for high-volume water movement.

A correctly sized delivery pipe helps reduce friction losses and maintain useful water flow.

Why Pipe Size Matters

At high flow rates, pipe diameter has a major effect on system performance.

An undersized delivery pipe increases:

• Friction
• Pressure loss
• Energy consumption
• Pump operating head

This can greatly reduce the water reaching the storage tank.

The complete pipeline should therefore be sized according to the required operating flow, total pipe length and pump curve.

High-Pressure Pipe Is Essential

A pump capable of producing 210m maximum head can generate substantial pressure.

As a rough static conversion:

10m of water head is approximately 1 bar

so 210m represents roughly 21 bar of water-column pressure near shut-off conditions.

This does not mean every part of a working system will continuously operate at 21 bar.

However, it shows why cheap low-pressure pipes and fittings should not be used.

6-Inch Pump Class

The matching 36m³/h pump family is a 6-inch class submersible pump.

This is larger than the common 4-inch borehole pumps used for homes and small farms.

Before installation, confirm:

• Borehole casing internal diameter
• Pump outside diameter
• Cable clearance
• Water flow around the motor
• Borehole straightness

A large pump should never be forced into an undersized borehole.

Stainless Steel Impeller

Comparable 11kW AC/DC models in this pump family are available with stainless steel impellers.

Stainless steel offers:

• Good corrosion resistance
• Mechanical strength
• Long service life
• Suitability for clean-water pumping

It is useful in high-capacity borehole systems expected to operate for long periods.

Brushless Motor Technology

The comparable 6-inch AC/DC hybrid pump range uses a brushless motor design.

A brushless system avoids carbon brushes that would otherwise wear during operation.

Benefits can include:

• Reduced motor maintenance
• High efficiency
• Good solar performance
• Long operating life
• Smooth controller operation

IP68 Protection

The matching 11kW pump currently sold in Kenya is specified with IP68 protection.

IP68 is appropriate for equipment designed to operate submerged under manufacturer-specified conditions.

The external controller and electrical switchgear should still be installed in a suitable protected location.

Heavy-Duty Irrigation Pump

The 36m³/h maximum flow makes this pump especially attractive for agriculture.

It can support properly designed:

• Drip irrigation
• Sprinkler systems
• Centre-pivot support systems
• Greenhouses
• Orchards
• Horticulture
• Coffee farms
• Fruit farms
• Vegetable farms

Actual irrigation capacity depends on the pump’s flow at the system’s required operating pressure.

Large-Scale Tank Filling

At low pumping head, a maximum flow of 36,000L/hr allows large tanks to be filled quickly.

Tank Capacity	Theoretical Minimum Filling Time
5,000 L	About 8 minutes
10,000 L	About 17 minutes
20,000 L	About 33 minutes
50,000 L	About 1 hour 23 minutes
100,000 L	About 2 hours 47 minutes
200,000 L	About 5 hours 33 minutes

These times assume the full 36m³/h maximum flow.

Deep installations will take longer because actual flow decreases with increasing head.

Commercial Farming

An 11kW hybrid pump is particularly suitable for commercial farms that require large quantities of water every day.

It can be used for:

• Crop irrigation
• Livestock water
• Reservoir filling
• Farm tank filling
• Water distribution

Solar operation can reduce dependence on diesel generators or grid electricity during sunny hours.

Institutions and Estates

The pump can also be used for large water-supply projects serving:

• Schools
• Universities
• Hospitals
• Hotels
• Apartment estates
• Factories
• Lodges
• Commercial buildings

The large flow rate is useful where water demand is much higher than in a normal household.

Borehole Yield Must Be Checked

A pump capable of 36m³/h requires a productive water source.

36m³/h is 10 litres every second.

If a borehole can sustainably produce only 8m³/h, installing a pump capable of 36m³/h does not increase the underground water supply.

Over-pumping can lead to:

• Severe drawdown
• Dry running
• Sand entry
• Pump damage
• Borehole problems

A professional borehole test should be used when selecting a pump of this size.

11kW Pump vs 7.5kW Pump

Feature	7.5kW Model	11kW Model
Power	7.5kW	11kW
Maximum Flow	36m³/h	36m³/h
Maximum Head	About 145m	210m
Outlet	3″	3″
Solar Array	Smaller	Larger
Best For	Medium-High Head	Higher Head

In the same matching pump family, moving from 7.5kW to 11kW increases maximum head from approximately 145m to 210m while maintaining the 36m³/h maximum-flow class.

This means the main advantage of the 11kW model is its greater pressure capability.

11kW vs 15kW Pump

The same series also includes a 15kW version rated at approximately:

• 36m³/h maximum flow
• 270m maximum head
• 3-inch outlet

Choose the 15kW version only when the required operating head justifies the larger motor and solar array.

Oversizing increases both equipment and installation costs.

Water Storage Instead of Batteries

Large solar pumping systems often work best by storing water rather than electricity.

During sunny hours, the solar panels run the pump and fill a large tank or reservoir.

Stored water can then be used later.

This can reduce the need for an expensive battery bank capable of running an 11kW motor.

Dry-Run Protection

Dry running can seriously damage a large borehole pump.

A suitable system should include water-level monitoring or dry-run protection.

The pump should stop if the borehole water level falls below a safe point.

For a commercial 11kW installation, this protection should be treated as an important part of the system rather than an optional extra.

Tank-Level Control

A tank float switch or level sensor can be connected to a compatible pump controller.

When the tank becomes full, the controller can stop pumping.

When the water falls to a set level, the system can restart when suitable power is available.

This helps prevent:

• Tank overflow
• Water waste
• Unnecessary pump operation

Installation Requirements

A professional 11kW AC/DC installation may require:

• 11kW submersible pump
• Hybrid pump controller
• Solar panels
• Solar mounting structure
• DC isolator
• DC surge protection
• AC protection
• Earthing
• Submersible cable
• Waterproof cable joint
• 3-inch rising main
• Non-return valve
• Borehole headworks
• Dry-run sensor
• Tank-level control

A Kenyan public borehole specification for an 11kW hybrid pumping system likewise calls for solar modules, a solar controller, cable interconnection, earthing and DC PV isolation as part of the installation.

Professional Electrical Installation Is Essential

This is a high-power, high-voltage pump.

The matching models use approximately 380V AC and more than 500V DC.

The installation should therefore be carried out by technicians experienced in:

• Three-phase electricity
• High-voltage DC solar systems
• Borehole pumps
• Earthing
• Surge protection
• Motor controllers

Improper wiring can cause serious equipment damage and electrical hazards.

Maintenance

A well-designed submersible system requires limited daily maintenance, but performance should be monitored.

Regular checks should include:

• Pump flow
• Controller readings
• Solar panel condition
• AC voltage
• DC voltage
• Tank filling time
• Borehole water level
• Pipe leakage
• Electrical connections

Solar panels should also be cleaned when dust or dirt significantly reduces output.

Signs That the System Needs Attention

Check the system if you notice:

• Reduced water output
• Frequent controller faults
• Pump stopping unexpectedly
• Unusual current readings
• Longer tank filling times
• Low solar production
• Sand in the pumped water

Finding the problem early can prevent expensive pump or motor damage.

Benefits of the 11kW AC/DC Pump

This large hybrid pump offers several important benefits:

• 11kW / approximately 15HP motor
• 36,000L/hr maximum flow
• 600L/min maximum flow
• 210m maximum head
• 3-inch outlet
• AC and solar DC operation

• Suitable for commercial water projects
• Reduced dependence on fuel

How to Choose an 11kW AC/DC Pump

Before purchasing this pump, obtain the following information:

• Borehole total depth
• Casing diameter
• Static water level
• Dynamic water level
• Tested borehole yield
• Required litres per hour
• Tank elevation
• Horizontal pipe distance
• Pipe diameter
• Required pressure
• Available AC supply
• Solar panel space

Then calculate Total Dynamic Head and compare it with the pump’s performance curve.

Do not select an 11kW pump simply because the borehole is deep.

11kW AC/DC Pump Price in Kenya

Current Kenyan listings show an exact-spec 11kW, 210m-head, 3-inch hybrid solar submersible pump at around KSh 170,000 for the pump listing.

The complete solar pumping project will cost considerably more because an 11kW system also needs a large solar array, controller, structure, cables, pipes, electrical protection and installation.

Component	Expected Cost Level
