Quick Takeaways

• A drainage pump evacuates water from flooded areas, basements, septic tanks, and fields.
• Submersible pumps are the most popular for basements and septic systems.
• Drainage pump prices in Kenya range from KES 7,000 to KES 45,000+ depending on size and type.
• Automatic float switches allow pumps to activate when water rises.
• Heavy-duty pumps are ideal for construction and large flood situations.
• Regular maintenance can extend pump life to 10 years or more.

What Is a Drainage Pump?

A drainage pump is a pump used to remove water from flooded basements, construction sites, or wastewater from septic tanks.

It works by sucking in water and pushing it through a discharge pipe to another location.

Drainage Pump Price in Kenya

The cost of drainage pumps varies depending on power, capacity, and brand.

How Does a Drainage Pump Work?

Drainage pumps evacuate water by impeller rotation, which causes a pressure drop that results in suction and discharge through the pump outlet.

Types of Drainage Pumps

Choosing the right type depends on the water condition, depth, and volume.

Submersible Drainage Pump

Submersible pumps move water while completely submerged. They operate quietly and are designed with sealed motors for higher efficiency.

We have centrifugal submersible pumps with an open impeller for turbid water and a closed impeller (vortex) for water containing high silt loads.

Submersible pumps can move large volumes of water quickly and are ideal for dirty water applications.

Positive Displacement Pumps

This type of pump traps a fixed volume of water and pushes it through the discharge pipe.

Ideal for handling sludge or wastewater with high solid content.

Pedestal Drainage Pump

These pumps keep the motor above the water while the intake sits in the sump. Relatively cheaper and easy to maintain but are less powerful than submersible pumps.

Heavy-Duty Drainage Pump

Heavy-duty drainage pump is designed for demanding water transfer applications such as construction sites, mining and industrial sites.

Can move up to 40 cubic metres of water per hour.

How to Select the Right Drainage Water Pump

Flow Rate

Ensure that you acquire a pump that matches the desired flow rate to handle the demands of your application.

Head

Buy a pump that can move water efficiently over the vertical distance from the source where you want to transfer to.

Solid Content

For water with high solid content, a closed impeller drainage pump would be ideal. If water contains less solid, use an open impeller pump.

Power

The type of power required to operate the pump. Consider a pump that consumes reliable power.

Components of Drainage Pumps

• Pump Motor: powers the pump by converting electric energy to mechanical energy that moves water.
• Impeller: pushes water to the discharge pump by spinning to create a pressure drop that draws water.
• Float Switch: a device that is designed to control the water level. Connected to the pump, and it triggers the pump to start when the water level rises to the set height. If the water level drops to the lower set level, it shuts off the pump.
• Discharge pipe: for discharge of water from the pump. Should be sized to match the pump’s output.
• Check Valve: prevents pumped water from flowing back to the sump.

Drainage Pumps for Septic and Dirty Water

For septic or dirty water with high solid content, the drainage pump should be designed with strong impellers and corrosion-resistant materials. Vortex impellers with large particle handling are more efficient for dirty water.

Many sewage pumps can pass particles up to 35 mm in diameter.

Common Uses of Drainage Pumps

• Dewatering flooded basements
• Draining swimming pools. Can be used to move water when cleaning swimming pools.
• Septic tank or sewage containment area draining.
• Evacuating water from flooded construction sites.
• Mining site drainage applications
• Irrigation water transfer.

Common Issues with Drainage Pumps

• Unusual Noise: a rattling sound means the impeller is clogged with debris.
• Slow drainage: if the pump runs for long hours and discharges low water volume, the impeller could be partially blocked.
• frequent cycling: constant starting and stopping of the pump due to low pumping efficiency, often due to blockages.

Maintenance Tips for Drainage Pumps

• Clean the intake regularly
• Inspect the float switch
• Check the discharge pipe for blockages
• Test the pump twice per year
• Replace worn impellers

Frequently Asked Questions

1. What is a drainage pump used for?

To pump water from flooded areas like basements, septic tanks, wells, and construction sites.

2. How much is a drainage pump in Kenya?

KES 9,000 – KES 50,000.

3. How do drainage pumps work?

It uses a motor-driven impeller to move water through an outlet pipe and away from the flooded area.

4. What type of pump is best for a basement drainage system?

Submersible sump pumps are best because they operate quietly underwater and pump large volumes quickly.

5. What is the best drainage pump type?

Submersible drainage pump. It is quiet, has a compact design and has efficient performance.

6. Can a drainage pump handle dirty water?

Yes. Vortex pumps are ideal for dirty water with high solid content.

7. How deep can a submersible drainage pump operate?

Many pumps can operate up to 7 metres underwater depending on the model.

8. What are common drainage pump problems?

• Float switch not working.
• Check Valve not operating properly; thus, water flows back to the sump
• A faulty impeller causing thus no pumping to occur completely.

9. What are signs of a failing drainage pump?

Unusual noise, cycling, low water flow, and the pump failing to discharge water completely.
