Types of Drainage Pumps

1. Submersible Drainage Pumps

Submersible drainage pumps are designed to operate when fully submerged in water, offering a highly efficient and versatile solution for water removal. These pumps are typically used in situations requiring high capacity pumping and are ideal for applications such as basement drainage, flood control, and general dewatering tasks. Submersible pumps come equipped with durable, corrosion-resistant materials, making them suitable for handling various fluids, including both clean and dirty water.

2. Sump Pumps

Sump pumps are a particular type of drainage pump utilised in the removal of accumulated water from sump pits, commonly found in basements or crawlspaces. These pumps are available in submersible or pedestal configurations, depending on the specific requirements of the application. The primary purpose of sump pumps is to protect properties from water damage and flooding by maintaining a dry and safe environment.

3. Self-Priming Pumps

Self-priming drainage pumps are designed to eliminate the need for manual priming, where the pump must be filled with water before operation. This feature makes self-priming pumps more user-friendly and low-maintenance, as they are capable of removing air from the suction line and preventing air-locking issues. These pumps are typically used in situations where rapid, short-term water removal is required, such as during flooding emergencies or routine maintenance tasks.

4. Centrifugal Drainage Pumps

Centrifugal drainage pumps use centrifugal force to move water through the pump’s impeller, creating a high-speed flow of fluid that is discharged at the outlet. These pumps are often utilised in large-scale commercial and industrial applications, offering powerful and efficient water removal capabilities. Additionally, they are available in various designs and materials to cater to different needs and fluids, making them highly adaptable for a wide range of drainage applications.

Essential Features of Quality Drainage Pumps

1. Corrosion-Resitant Materials

A quality drainage pump should be constructed from corrosion-resistant materials to ensure long-lasting, reliable performance even when exposed to harsh or aggressive fluids. Common materials used in drainage pump construction include stainless steel, cast iron, and plastic, each offering its benefits and specific applications.

2. Appropriate Flow Rate and Head Capacity

Selecting a drainage pump with the appropriate flow rate and head capacity is crucial in ensuring optimal performance and efficiency. Flow rate refers to the volume of fluid the pump can move within a set time frame, typically measured in litres per minute (L/min) or gallons per minute (GPM). In contrast, head capacity indicates the vertical distance the pump can raise fluid against gravity, commonly measured in metres or feet.

3. Reliable Motor

A high-quality motor is an essential component of any efficient drainage pump. Motors should be energy-efficient, robust, and capable of providing the necessary power to accommodate the pump’s capacity. Ensure that the motor’s voltage, phase, and frequency ratings are compatible with the available power sources to guarantee optimal performance.

4. Automatic Functionality

Modern drainage pumps often come with automatic features, such as float switches or sensors, to detect water levels and initiate or stop the pump’s operation accordingly. This feature not only increases convenience but also minimises the risk of water damage and flooding by ensuring that the pump operates when needed without human intervention.

Best Practices for Efficient Water Removal

1. Select the Right Pump for Your Application

Before installing any drainage pump, consider factors such as the type of fluid, depth and size of the area requiring drainage, and the required flow rate and head capacity. Assessing these factors will ensure that you select the most suitable pump for your specific needs, ensuring optimal performance and efficiency.

2. Regular Maintenance and Inspection

To maintain the longevity and efficiency of your drainage pump, schedule regular maintenance and inspection checks. Keeping an eye on the pump’s components, such as the motor, impeller, and seals, can help identify and address any issues before they escalate. Additionally, make sure to clean the pump and its components periodically to avoid clogging or buildup of debris.

3. Monitor Water Levels

Keep track of water levels in the area where the pump is installed, whether through manual checks or automatic monitoring systems. By monitoring water levels, you can detect changes indicative of potential issues, such as malfunctioning equipment, leaks, or blockages, and address them promptly.

4. Proper Storage and Winterisation

If your drainage pump is not in use during colder months, make sure to store it correctly and apply appropriate winterisation measures such as draining the pump and protecting it from freezing temperatures. Proper storage and winterisation will help maintain the pump’s performance and extend its lifespan.


Understanding the diverse range of drainage pumps, their features and the best practices for efficient water removal empowers you in managing your property’s drainage systems effectively. By selecting appropriate pumps, performing regular maintenance and monitoring water levels, you can protect your property from water-related damages, save on repair costs and maintain a healthy environment.
