Are you searching to buy the best irrigation pump in Kenya, and you do not know which pump to choose?

If that describes you, then you are at the right place.

Choosing the right water pump is a difficult when you think of the many options available.


There are so many water pump variables to consider.

For example:

  • Volume of water a pump is capable of pumping every hour,
  • The type of power—e.g. diesel, petrol/gasoline, or electricity,
  • Pressure—high pressure or low pressure,
  • Pump head (i.e. the maximum height the pump can raise water),
  • And the manufacturer/ brand e.g. Honda water pumps, Dayliff water pumps, Aico water pumps etc.

Will all these things to think about…

Choosing the best irrigation pumps in Kenya becomes so difficult.

To help you solve this problem, I decided to write this post.

I am doing it, so that when you decide to buy a water pump, you’ll will be thoroughly equipped with the right information so that whatever choice you make will be the right one for you.

As you read through this post, I will also make the best irrigation pumps recommendations that will be of great help to you.

Price of Pump and how it affects choice

When it comes to choosing the best water pump to buy in Kenya, price is often a KEY factor.

Price is important because you need to buy a pump that:

  • You can afford,
  • Will give you value for money,
  • and would perform according to expectations.

So if you are thinking about the price of a water pump you are on the right path.

Nevertheless, choosing a water pump SORELY on price is not ideal.

Instead of thinking about the price only, think about all the other features of the water pump.

For example:

Think about the;

  • Flow rate per minute—this is the amount of water a pump discharges per minute,
  • The head of the pump—which refers to the height a pump can raise water/fluid and it is measured in feet.
  • Pump type—centrifugal, or submersible pump,
  • Brand,
  • Type of power—e.g. Electricity, Diesel, Petrol
  • Horse power

Consider the impact of the above features on efficiency of farm operations, and profitability.

When you think about all these, you will discover, “You ought to buy the right water pump at the right price.”

For that reason, this post will be helping you choose the right water pump at the right price.

How Choose the Right Water Pump According to Your Farm Requirements

This is the most important part of this post… and you can’t miss it if you want to buy the right water pump in Kenya.

Here I will discuss in details the various factors to consider before you make your choice.

Size of the farm and how it impacts on the choice of your water pump

Irrigation requires huge amounts of water.

Depending on the type of soil on your farm, 1 acre requires over 102,000 liters of water which translates to 1 inch of rainfall.

To meet this huge water demand, you must have a pump that matches the size of your farm.

And as a general rule, the bigger your farm, the more powerful pump you will need.

On the other hand, the smaller your farm, the less powerful the water pump you need.

A bigger farm will require a more powerful pump because:

  1. The farm will need more volume of water,
  2. It will need more time to cover the entire field with water.

And the converse is true.

That said, let us look at the water pump options available in the Kenyan market.

Honda WL XY 3” Water Pump

The key features of this pump that will have an impact on irrigation efficiency are as follows:

  • Feature 1#. Flow Rate

The maximum flow rate per minute for this pump is 1,100 liters.

Often, water pumps are never operated at their max, so getting this flow rate will not be possible.


Operating pumps at their max will mean that the pumps will be operating at maximum revolutions per minute.

Doing this has two disadvantages:

  1. It reduces pump life,
  2. The pump becomes inefficient in fuel consumption.

So for our pump above, the ideal flow rate per minute will be 950 liters of water.

This means in one hour the pump will deliver 57,000 liters of water.

Assuming you work for 5 hours in a day, the pump give 285,000 liters of water.

As a general rule, 102,000 liters of water applied on 1 acre equivalent to 1inch of rainfall.

So after 5 hours of irrigation, you will have supplied your farm 2.85 inches of rainfall.

So this pump is ideal for irrigating 2-3 acres of land if you

  • Feature #2: 4HP

The 4 HP in this petrol water pump stands for 4 horsepower, a unit of power that reflects the engine’s capability.

In simple terms, it measures the pump’s ability to perform work, indicating a higher power output.

This translates to increased efficiency in pumping water, making it suitable for more demanding tasks.

The higher the horsepower, the more robust and powerful the pump is, enabling it to handle larger volumes of water or work against higher resistance.

However, it’s essential to note that while higher horsepower provides enhanced performance, it can also influence fuel consumption.

A 4 HP petrol water pump, being more powerful, may consume fuel at a relatively higher rate compared to lower horsepower alternatives.

The relationship between horsepower and fuel economy is not linear; as horsepower increases, fuel consumption often rises, affecting operational costs.

To maximize fuel efficiency, it’s crucial to match the pump’s horsepower to the specific requirements of your tasks.

Using a pump with excess horsepower for lighter applications may result in unnecessary fuel consumption.

Conversely, using an underpowered pump for more demanding tasks can lead to inefficiency and increased fuel usage as the engine strains to meet the workload.

Are you going to use drip irrigation or overhead irrigation?

For overhead irrigation and drip irrigation, the choice of a water pump is crucial, as each method has distinct requirements.

In overhead irrigation, where water is distributed in a broad spray over crops, a pump with sufficient horsepower and flow rate is essential.

A pump with a moderate to high horsepower, such as a 4 HP petrol water pump, is suitable.

This power ensures the pump can propel water over a considerable distance, covering a large area effectively.

Additionally, a pump with a good flow rate is beneficial for delivering water evenly across the field.

On the other hand, drip irrigation operates on a more precise and controlled system.

Drip systems require consistent and lower pressure to deliver water directly to the plant’s roots through a network of tubes and emitters.

For drip irrigation, a pump with lower horsepower and a steady flow rate is preferable.

This ensures a gentle and controlled release of water, preventing damage to the drip system components and providing efficient water delivery to individual plants.

In both cases, it’s essential to consider the total head, which includes factors like elevation changes and pipe friction.

Overhead irrigation may require higher total head capacity due to the need to lift water to greater heights, while drip systems typically operate with lower total head requirements.

Choosing the right water pump depends on the specific needs of your irrigation system.

Whether it’s overhead or drip irrigation, matching the pump’s horsepower, flow rate, and total head capacity to the system’s requirements ensures optimal performance and water efficiency.
