Drainage pumps play a crucial role in preventing waterlogged areas and safeguarding properties from potential water damage. If you’re considering water pump installation on your property, it can be beneficial to have a basic understanding of how this vital component works so that you can make an informed decision and know when to consult a professional should any maintenance issues arise further down the road.
In this blog post, we’ll delve into the inner workings of drainage pumps, shedding light on their functionality and the benefits they bring to both residential and commercial spaces.
The Basics of Drainage Pumps
Put simply, drainage pumps are designed to move water from one location to another. Whether it’s excess rainwater, groundwater or wastewater, these pumps excel at keeping areas surrounding the drainage system dry and flood-free. Before getting into specifics, let’s take a look at the basic principles of drainage pumps:
Inlet: Drainage pumps are strategically positioned in low-lying areas or collection points where water naturally accumulates.
Impeller: The impeller lies at the heart of the drainage pump and uses rotating vanes or blades to draw in water and create a flow of liquid.
Casing: Surrounding the impeller is a chamber or casing. As the impeller rotates, it generates a centrifugal force that propels the water outward into the surrounding chamber.
Outlet: The pumped water is then directed through an outlet or discharge pipe to its intended destination - usually a water treatment facility or larger drainage system.
Submersible vs. Non-Submersible Pumps
Submersible and non-submersible water pumps are designed for different applications and operate in distinct ways. Here are the key differences in how they work:
Submersible Water Pumps
Submersible pumps are designed to be submerged in the water being pumped and, unlike surface pumps that need to pull water, they push water from below. This design not only ensures a constant and reliable water flow but also minimises the risk of cavitation, a phenomenon that can damage pumps over time.
They are sealed units, meaning they are enclosed in a waterproof casing to protect the internal components from water. This design allows them to operate efficiently when fully submerged and enhances the pump's durability and longevity, making it an ideal choice for continuous water management.
Submersible pumps are commonly used in applications where the pump needs to be placed deep underwater, such as in wells, boreholes, or sump pits. They are also used in applications where the pump needs to be fully submerged to prevent cavitation or priming issues.
Non-Submersible Water Pumps
On the other hand, non-submersible pumps or surface pumps are designed to be placed outside the fluid being pumped. This means they are usually positioned above the water level and draw water in through an inlet pipe using suction.
Non-submersible pumps are used in situations where the pump can be positioned above the fluid source, such as in surface water pumping for irrigation, water supply systems, or other industrial applications.
