Description
Submersible pumps are essential tools used for moving liquids, especially water, from one place to another. These pumps are designed to operate while completely submerged in the liquid, making them highly efficient for tasks such as draining water from wells, pools, or even for agricultural irrigation. In this blog, we will discuss what submersible pumps are, their types, leading brands, prices, and how they perform. Let’s dive in!
What Are Submersible Pumps?
A submersible pump is a device designed to work underwater. It consists of a motor that is sealed and housed in a waterproof case to prevent any damage. Unlike other pumps that sit above the water level, submersible pumps are placed directly in the liquid, and the pump works by pushing the liquid to the surface. This design is highly efficient because it eliminates the need for priming and reduces energy loss.
Types of Submersible Pumps
There are several types of submersible pumps, each designed for different applications. Here are the most common ones:
1. Sump Pumps
Sump pumps are used for removing water from basements, trenches, and other areas prone to flooding. They are typically used in residential settings to prevent water buildup.
2. Well Pumps
Well pumps are used to extract water from deep wells. These pumps are capable of handling both clean and slightly contaminated water. They are commonly used in homes that rely on well water for their daily needs.
3. Dirty Water Pumps
These pumps are designed to handle water that contains debris such as mud, leaves, and other solid particles. They are often used for drainage and construction site applications.
4. Submersible Water Pumps for Irrigation
These pumps are used in agricultural applications to provide water for irrigation. They are capable of lifting water from deep underground sources to the surface for efficient watering of crops.
Leading Brands of Submersible Pumps
When choosing a submersible pump, the brand is important for ensuring quality and reliability. Here are some of the top brands in the market:
1. Grundfos
Grundfos is a global leader in the pump industry. Known for its reliable and energy-efficient pumps, Grundfos submersible pumps are widely used in residential, commercial, and industrial applications.
2. Franklin Electric

3. Sulzer
Sulzer submersible pumps are known for their innovative designs and long-lasting performance. They offer a variety of pumps for various industrial and residential uses.
4. Zoeller
Zoeller is a trusted brand for sump pumps and sewage pumps. Their submersible pumps are designed to handle both clean and dirty water, making them versatile for many applications.
Prices of Submersible Pumps
The price of a submersible pump depends on factors such as its type, brand, and power capacity. Below is an estimate of prices you might encounter in the market:
-
Sump Pumps: Prices typically range from KSh 5,000 to KSh 20,000, depending on the size and features.
-
Well Pumps: These pumps can cost anywhere between KSh 15,000 and KSh 60,000, with the more powerful models being on the higher end.
-
Dirty Water Pumps: Prices range from KSh 10,000 to KSh 40,000, depending on the quality and capacity.
-
Irrigation Pumps: These pumps usually cost between KSh 10,000 and KSh 50,000, depending on the pump’s size and efficiency.
Performance Curves of Submersible Pumps
Performance curves are graphical representations of a pump’s capacity to move water against various heads or pressures. The curve indicates the flow rate (in liters per minute or gallons per minute) at different depths or pressure levels. Here’s a simple example of a performance curve for a submersible pump:
A typical performance curve will show:
-
Flow Rate: The amount of water the pump can move in a given time.
-
Total Head: The height that the pump can lift the water.
The curve helps determine the most suitable pump for your needs by matching the flow rate and total head to your system’s requirements.
