Description

A 1.25HP shallow well pump is a powerful water extraction pump designed for wells, water tanks, farms, homes, irrigation systems and general water-transfer applications. This model combines a maximum head of 60 metres with a maximum flow rate of 7.2m³/h, giving a good balance between water pressure and water volume.

The pump comes with an electrical cable and controller box, making installation easier than buying the main electrical control components separately. A 1.25HP motor is approximately 0.93kW or 930W, which places this pump above small 0.5HP and 0.75HP well pumps while remaining economical for domestic and light agricultural water supply.

Current comparable 1.25HP well pumps sold in Kenya include the Doyin SCM5, which is rated at approximately 930W, 6.6m³/h and 64m maximum head. This is very close to the 1.25HP, 60m-head performance class of the pump described here.

A current 1.25HP Doyin SCM5(A) listing specifies 220–240V, 50Hz power, about 920W motor input, 60m maximum head and flow from 20 to 120L/min.

Maximum Flow Rate of 7.2m³/h

One of the strongest features of this pump is its maximum flow rate of:

7.2 cubic metres per hour

That equals:

7,200 litres per hour

or:

120 litres per minute

This amount of water makes the pump suitable for applications where a small domestic pump may take too long to fill tanks or supply farm water.

Estimated Maximum Water Output

Running Time	Maximum Theoretical Water Output
30 Minutes	3,600 L
1 Hour	7,200 L
2 Hours	14,400 L
4 Hours	28,800 L
6 Hours	43,200 L
8 Hours	57,600 L

These figures are theoretical maximum-flow calculations.

The pump will not normally produce 7,200 litres per hour when it is working close to its maximum 60m head. Water flow decreases as pumping pressure and vertical lift increase.

60 Metres Maximum Head

The pump has a maximum head of 60 metres.

This means it can generate pressure equivalent to approximately a 60m vertical column of water under maximum-head conditions.

It is useful for moving water from:

• Shallow and medium-depth wells
• Underground storage
• Ground tanks
• Farm water sources
• Lower ground to elevated tanks

Current 1.25HP well-pump listings in Kenya show very similar performance. One Doyin SCM5(A) is rated at 60m maximum head, while other SCM5 listings show approximately 64m maximum head depending on the version.

Maximum Head Is Not Maximum Flow

The 60m head and 7.2m³/h flow are maximum limits, not necessarily one operating point.

At lower delivery pressure, the pump can produce more water.

As the head increases toward 60m, flow falls.

For this reason, a pump should be selected using the required operating flow and Total Dynamic Head rather than simply comparing maximum figures.

Powerful 1.25HP Motor

The pump uses a 1.25HP motor, equal to roughly:

0.93kW or 930W

Current 1.25HP well pumps in this category are commonly listed between about 920W and 930W.

This power is suitable for users who need more performance than a 0.5HP or 0.75HP water pump.

The extra motor capacity helps the pump provide:

• Higher water pressure
• Greater vertical lift
• Faster tank filling
• Better irrigation performance
• Higher overall water output

High-Speed Motor Performance

Comparable 1.25HP AC well pumps operate at approximately 2850rpm.

The high-speed motor drives the pumping system efficiently and provides the pressure required for water lifting and distribution.

High rotational speed is particularly useful where the pump must supply both reasonable flow and strong pressure.

220–240V Single-Phase Power

Comparable 1.25HP well pumps in Kenya operate from ordinary 220–240V, 50Hz single-phase electricity.

This makes the pump practical for:

• Homes
• Farms
• Shops
• Schools
• Small institutions

It can also be operated from a properly sized generator where grid electricity is unavailable, provided the generator voltage and starting capacity match the motor and controller requirements.

Electrical Cable Included

This shallow well pump comes with its electrical cable included.

The cable carries power from the controller to the pump motor.

This is especially useful when the pump itself is installed inside a well or other submerged water source.

The exact supplied cable length should be confirmed on the specific unit before installation. If additional length is needed, use approved submersible cable and a properly waterproofed cable joint.

Controller Box Included

The package also includes a controller box.

On a single-phase submersible pump, an external controller box may contain components needed to start and protect the motor.

Depending on the exact model, these can include:

• Capacitor
• Overload protection
• Motor starting components
• Terminals
• On/off control

The precise functions should always be checked on the controller supplied with the pump.

Why the Controller Box Is Important

A controller box does more than provide a convenient electrical connection.

It helps the motor operate correctly and may provide basic protection against abnormal electrical conditions.

Correct wiring is important because an incorrectly connected control box can cause:

• Motor overheating
• Failure to start
• Capacitor damage
• Excessive current
• Motor winding failure

Installation should be carried out by a qualified electrician or pump technician.

Built-In Thermal Protection on Comparable Models

Some current 1.25HP well pumps also include a thermal protector to help protect the motor against overheating. A current SCM5(A) listing specifically states built-in thermal protection.

Thermal protection is valuable when a motor experiences excessive temperature due to:

• Low voltage
• Overloading
• Restricted water flow
• Electrical problems

It should not replace correct pump sizing and electrical installation.

Copper Motor Winding

A current comparable 1.25HP SCM5(A) pump is advertised with heavy-duty copper winding for durability and motor performance.

Copper windings generally offer good electrical conductivity and are widely used in quality water-pump motors.

When comparing pumps, it is useful to check whether the exact unit uses genuine copper motor windings.

Submersible Well Pump Design

Unlike a normal surface pump, a submersible well pump is installed in the water.

This provides several benefits:

• No long suction pipe
• No traditional surface-pump priming
• Quiet operation
• Good water lifting performance
• Motor and pump protected inside the well

A current Doyin SCM5 is marketed in Kenya as an AC submersible well pump for homes, gardens, farms and similar water-supply applications.

Shallow Well Pump vs Surface Self-Priming Pump

The term shallow well pump can refer to more than one pump design.

Some shallow-well pumps are surface-mounted jet pumps. Others are submersible well pumps installed directly in the water.

Because this model is supplied with an electrical cable and controller box, it fits the submersible well-pump type rather than a conventional surface-mounted jet pump.

Feature	Submersible Well Pump	Surface Jet Pump
Position	Inside Water	Above Ground
Priming	Normally Not Required	Usually Required
Suction Limitation	Less Restrictive	Usually Around 8–9m
Noise	Low	Higher
Cable to Pump	Yes	No Submerged Motor Cable
Controller Box	Common on Some Models	Less Common

This difference is important when selecting a pump for a well.

Suitable for Wells

The pump is designed for water extraction from wells.

It can be useful where homeowners or farmers need to move water into:

• Storage tanks
• Header tanks
• Irrigation tanks
• Livestock tanks
• Domestic plumbing systems

The water source should provide enough water to match the required pumping rate.

Tank Filling

With a theoretical maximum flow of 7,200L/h, the pump can fill storage tanks relatively quickly.

Tank Size	Theoretical Minimum Filling Time
1,000 L	About 8 minutes
2,000 L	About 17 minutes
5,000 L	About 42 minutes
10,000 L	About 1 hour 23 minutes
20,000 L	About 2 hours 47 minutes

Actual filling times depend on the working head, pipe diameter and water level.

Suitable for Domestic Water Supply

The pump can supply water for a home when connected to a correctly designed storage system.

Common applications include:

• Kitchen water
• Bathrooms
• Laundry
• Garden taps
• Water storage tanks

For automatic direct-pressure systems, extra components such as a pressure controller or pressure tank may be required.

Suitable for Irrigation

A flow rate of up to 7.2m³/h also makes the pump useful for small and medium farm irrigation.

Applications can include:

• Drip irrigation
• Kitchen gardens
• Greenhouses
• Nurseries
• Vegetable farms
• Orchard watering

The number of drip lines or sprinklers that can operate at once depends on the pump’s actual flow at the required pressure.

Livestock Water Supply

The pump can be used to fill livestock drinking tanks for:

• Dairy cattle
• Beef cattle
• Poultry
• Pigs
• Goats
• Sheep

A storage tank provides a reserve even when the pump is switched off.

Water Transfer

The pump can also transfer clean water between:

• Wells and tanks
• Ground tanks and elevated tanks
• Farm reservoirs
• Storage systems

Its combination of 7.2m³/h maximum flow and 60m head gives it more flexibility than small low-head transfer pumps.

Total Dynamic Head

Correct pump selection should consider Total Dynamic Head, or TDH.

This includes:

Pumping water level + tank elevation + pipe friction + fitting losses + required pressure

For example:

Requirement	Head
Pumping Water Level	30m
Tank Elevation	10m
Pipe and Fitting Loss	5m
Total Dynamic Head	45m

You would then need to know the pump’s flow at approximately 45m head.

A 60m maximum-head rating alone cannot tell you that.

Well Yield Is Important

A pump cannot continuously deliver 7.2m³/h if the well itself produces much less water.

Before installing a high-flow pump, check the water source yield.

If the well produces only 3m³/h and the pump continuously attempts to remove more water, the water level can fall until the pump runs dry.

Dry-Run Protection

Dry running is one of the main risks for a submersible well pump.

It occurs when water falls below the pump intake or motor cooling level.

A suitable low-water sensor, dry-run protector or automatic pump controller can help protect the pump.

Do not assume that the standard controller box automatically provides dry-run protection unless that feature is stated on its label or manual.

Pump Controller vs Automatic Pressure Controller

These are not always the same device.

The motor controller box supplied with the pump operates the motor.

An automatic pressure controller is an additional device that can automatically start or stop a pump according to water demand.

Current Kenyan suppliers list automatic Doyin pump controllers separately at around KSh 6,500, showing that an automatic water-pressure controller can be a separate accessory from the normal motor control box.

Comparable Outlet Size

The exact outlet size of the 7.2m³/h version should be checked on the physical pump before choosing the delivery pipe.

For reference, current Kenyan listings for the comparable Doyin SCM5 1.25HP specify a 2-inch outlet.

If your exact pump uses a 2-inch outlet, maintaining a correctly sized pipe can help reduce friction losses.

Choosing the Correct Delivery Pipe

A delivery pipe that is too small increases friction.

This reduces water flow and makes the pump work against unnecessary resistance.

When selecting the pipe, consider:

• Pump outlet diameter
• Flow rate
• Pipe length
• Vertical lift
• Pressure rating
• Number of bends
• Type of pipe

Long water lines particularly benefit from proper pipe sizing.

Installation Tips

For reliable installation:

• Confirm well depth.
• Check dynamic water level.
• Confirm water yield.
• Install the pump below the working water level.
• Keep it above sediment at the bottom.
• Use a properly rated delivery pipe.
• Use suitable submersible electrical cable.
• Waterproof all submerged electrical joints.
• Install the controller box in a dry location.
• Fit suitable electrical protection.
• Use dry-run protection where needed.

The pump should never be suspended by its electrical cable.

Do Not Install the Controller Box in Water

The pump itself may be submersible, but the external controller box generally is not.

Install the controller:

• In a dry location
• Away from rainfall
• Away from flooding
• With good ventilation
• Where it can be inspected

Use an appropriate weatherproof enclosure when necessary.

Electrical Protection

A 1.25HP motor should have suitable:

• Circuit breaker
• Earthing
• Overload protection
• Correct cable size
• Supply voltage

Long electrical cables can create voltage drop.

Have the cable size checked by an electrician when the well is deep or the power source is far from the installation.

IP68 on Comparable Submersible Models

A current comparable 1.25HP SCM5(A) listing specifies IP68 protection for the submerged pump assembly.

IP68 is commonly used for equipment designed for continuous submersion under specified manufacturer conditions.

This rating refers to the pump unit, not automatically to an external controller box.

1.25HP vs 0.75HP Well Pump

Feature	0.75HP Well Pump	1.25HP Well Pump
Motor Power	0.75HP	1.25HP
Head	Lower	Up to 60m
Maximum Flow	Lower	7.2m³/h
Tank Filling	Slower	Faster
Irrigation	Light	Better
Higher Elevation	Limited	Better

The 1.25HP version is a better option where greater water volume or stronger pressure is required.

1.25HP vs 2HP Pump

A 2HP pump is not automatically better.

If the well yield and system head match a 1.25HP model, installing a larger pump may:

• Increase electricity consumption
• Increase purchase cost
• Pump the well down too quickly
• Require larger electrical components

Correct sizing is more important than simply choosing the highest horsepower.

Maintenance

A properly installed submersible pump requires limited routine maintenance.

Monitor:

• Tank filling time
• Water flow
• Pump current
• Controller condition
• Supply voltage
• Cable condition
• Water level

A sudden drop in performance may indicate:

• Falling well level
• Pipe leakage
• Blocked pipe
• Low voltage
• Pump wear
• Sediment problems

• Controller type

Do not choose a pump from horsepower alone.

A 1.25HP pump can have very different performance depending on its impeller and hydraulic design.
