Submersible Water Pumps: Everything You Need To Know

Submersible water pumps are an essential tool for many households, farms, and industries in Kenya. Whether you need to access water from a borehole, irrigate crops, or drain a flooded area, a submersible pump is a powerful solution for moving water efficiently. But with so many options available, choosing the right pump for your specific needs can be overwhelming. In this guide, we will explore everything you need to know before buying a submersible water pump, including important factors. We’ll also provide answers to frequently asked questions (FAQs) to help you make an informed decision.

1. The Quality of Water Flow

Water flow rate is one of the most critical factors to consider when purchasing submersible water pumps. The flow rate refers to the amount of water the pump can move over a given period, usually measured in liters per minute (L/min) or cubic meters per hour (m³/h). The water flow you need depends largely on the intended use of the pump:

• Domestic Use: If you’re purchasing a pump for basic household needs, such as filling up tanks or watering a garden, a lower flow rate of around 20 to 40 liters per minute may suffice.
• Agricultural Use: If the pump is required for irrigation or for supplying water to livestock, you’ll need a higher flow rate to meet the demand, usually between 50 to 100 liters per minute or more.
• Industrial Use: For large-scale operations such as construction sites or draining flooded areas, a high-capacity pump with a flow rate of over 100 liters per minute is recommended.

The water flow quality also plays a role in how well the submersible water pumps perform over time. If the water is full of debris or dirt (as in the case of a flooded area), it will affect the flow rate, and the pump will require more frequent maintenance. Pumps that work with dirty water need to have strong filtration systems to maintain a good flow rate.

At Skywave, we offer submersible water pumps that are suitable for a wide range of applications, ensuring you find the right product with the appropriate flow rate for your specific needs.

2. Available Power: Solar or AC?

Another crucial factor to consider when buying submersible water pumps is the power source. In Kenya, where power reliability varies from region to region, it’s important to select a pump that aligns with the power options available to you.

• Solar-Powered Submersible Pumps: These pumps are ideal for off-grid areas where electricity is scarce or unavailable. Solar-powered pumps harness the sun’s energy to operate, making them eco-friendly and cost-effective in the long term. Although the initial setup might require a higher investment in solar panels and inverters, the benefits of solar power are hard to ignore, especially in sunny areas of Kenya. Solar-powered pumps are a great option for farmers and rural households that need a reliable, sustainable water source.
• AC-Powered Submersible Pumps: Alternating current (AC) pumps are powered by a grid or a generator. They tend to be more affordable initially compared to solar-powered pumps, but their operational costs may be higher due to the reliance on electricity or fuel. These pumps are more common in urban areas where power is readily available or where backup generators can be used to ensure a continuous water supply.

Choosing between solar and AC power depends on your location, budget, and the reliability of your power supply. Skywave offers both solar and AC submersible pumps to ensure you have access to a pump that suits your power requirements.

3. The Size of the Pipes

Selecting the correct pipe size is vital for the efficiency of your submersible water pumps. The diameter of the pipes you use will affect the water flow rate and the pump’s ability to move water efficiently. Here’s why pipe size matters:

• Large Pipe Diameters: Larger pipes allow more water to flow through, which means a higher flow rate. These pipes are commonly used in large-scale operations, such as boreholes or extensive irrigation systems where a lot of water needs to be transported over long distances.
• Small Pipe Diameters: Smaller pipes are more suitable for domestic use, such as garden irrigation, filling up water tanks, or supplying water to a single household. While they don’t allow for high flow rates, they are often adequate for everyday needs and are less expensive than larger pipes.

Before purchasing a submersible pump, you need to check the size of your existing pipes or plan out the pipework for your new pump. Mismatching pipe sizes can lead to reduced water flow, increased wear and tear on the pump, or even system failure.

4. Type of Water: Clean or Dirty?

The type of water you’ll be pumping is another critical factor in choosing the right submersible water pumps. Submersible pumps are designed to handle different water types, and selecting the wrong one can lead to poor performance or damage.

• Clean Water Pumps: These pumps are designed to handle water that’s free of debris, dirt, or other contaminants. Clean water pumps are commonly used for wells, boreholes, and other freshwater sources. If you’re drawing water for drinking, cooking, or irrigation, a clean water pump will meet your needs without any issues.
• Dirty Water Pumps: If you’re dealing with water that contains mud, leaves, or other debris, you’ll need a pump that’s specifically designed to handle dirty water. Dirty water pumps are ideal for draining flooded areas, ponds, or water sources that are contaminated with sediment. They have durable filtration systems that allow them to function efficiently in harsh conditions.

Using a clean water pump for dirty water can clog the system and lead to expensive repairs, so it’s essential to choose the right type of pump for the job. At Skywave, we provide pumps for both clean and dirty water applications, ensuring long-lasting performance no matter what type of water you’re dealing with.

5. Pump Depth and Pressure Requirements

Depending on how deep your water source is, you’ll need a pump that can handle the pressure required to move the water from the ground to the surface. submersible water pumps are designed to operate in deep water, but each model has a maximum depth it can handle. If you’re pumping water from a borehole or well, make sure you know the depth before purchasing a pump.

Additionally, consider the vertical distance the water must travel from the pump to your storage tank or distribution point. The higher the elevation, the more pressure you’ll need. Be sure to select a pump that can generate the required pressure to move the water efficiently.

6. Pump Material: Durability Matters

The material used in the construction of a submersible water pump determines its durability and suitability for various environments. Pumps made from high-quality, corrosion-resistant materials will last longer and perform better in challenging conditions. Here are some common materials to consider:

• Stainless Steel: Durable and corrosion-resistant, stainless steel pumps are ideal for use in boreholes or wells where they may come into contact with minerals or acidic water. These pumps are more expensive but offer a longer lifespan.
• Plastic or Composite: Lighter and more affordable, pumps made from plastic or composite materials are suitable for less demanding applications. However, they may not last as long in harsh conditions.
• Cast Iron: Cast iron pumps are strong and durable but can corrode over time, especially in salty or acidic environments.

Before purchasing a pump, assess the conditions in which it will be used and choose a material that can withstand those conditions.

7. Automatic Shutoff Features

Safety features, such as automatic shutoff, can protect your submersible water pump from damage. Pumps with an automatic shutoff feature will turn off when water levels drop too low, preventing the pump from running dry, which can cause overheating and damage to the motor.

Additionally, some pumps come with thermal protection that shuts the pump off if it begins to overheat, ensuring a longer lifespan and reducing the risk of damage.

8. Pump Installation: Professional Help vs. DIY

Installing submersible water pumps can be complex, especially for deep wells or boreholes. Some smaller pumps may be suitable for DIY installation, but in most cases, it’s advisable to hire a professional for installation. Improper installation can lead to:

• Reduced efficiency
• Increased wear and tear on the pump
• The potential for leaks and system failures

Consulting with a professional installer can ensure that your pump operates optimally from day one.
