Used in flooded basements, cellars, or individual sewage systems, these pumps ensure reliable and efficient evacuation, even in complex conditions.
What is a sewage pump?
A sewage pump is a device designed to transport water from a lower level to a higher level. This applies to both clear water and wastewater or charged water. These pumps are particularly useful in homes or buildings where natural water drainage is impossible, such as basements, cellars, or houses located below sewage networks.
Sewage pumps come in various types, suitable for clear, wastewater, or charged water. For example, a submersible pump is directly immersed in the water to be evacuated, while other models use a float to trigger pumping as soon as the water level becomes critical. Depending on your needs and the lifting height, you can choose a specific pump. Submersible sewage pumps are typically made from stainless steel or cast iron.
The sewage pump is installed in a sewage station, in a tank, a pit, a decompression well, a sump, or a designated cistern.
How does a sewage pump work? The principle of operation of a sewage pump is simple: it sucks up the wastewater or charged water and discharges it to a higher evacuation area. Depending on the models, the pump may be equipped with a float that detects the water level and automatically activates the pumping. Once the water is evacuated, the float descends, and the pump stops.
Submersible pumps are often used for flooded basements or cellars. They are submerged in water and can handle both clear and wastewater, or even charged water, depending on the chosen model. The pump's flow rate, which is the amount of water it can process over a given time, as well as the lifting height, are key parameters to consider for a successful installation.
These pumps come in various models to meet all configurations, whether it’s for a small flooded basement or a complete sewage system.
Why choose a sewage pump? Choosing a sewage pump suited to your needs helps avoid many inconveniences. Here are some reasons why installing a sewage pump is often essential:
- Evacuation of basement water: In the event of flooding, especially in basements, sewage pumps allow for rapid water evacuation to limit damage.
- Management of wastewater: Homes located below the sewer network require a sewage pump to effectively evacuate wastewater.
- Flexibility of installations: Whether you need to manage clear, charged, or wastewater, there is a wide variety of pumps suitable for different types of water and installations. You can choose a pump with an appropriate flow rate and sufficient lifting height to evacuate water to the outlet point.
How to choose your sewage pump? To choose your sewage pump from the available range, several criteria must be considered to effectively meet your specific needs:
1. Type of water to be treated: The first question to ask is about the nature of the water to be evacuated. Gray water comes from regular household activities. Black water is loaded with impurities. Charged water may result from flooding. Clear water includes drainage from pools or wells, as well as rainwater.
2. Granulometry of the water: This measurement corresponds to the maximum diameter of particles present in the wastewater. For household water, the pump's granulometry should be between 5 mm and 20 mm. For water with food waste or black water, plan for a granulometry of 20 to 50 mm. For heavily charged water, it should be over 50 mm.
3. Flow rate and lifting height: The pump's flow rate, expressed in liters or cubic meters per hour, is an indicator of its capacity to quickly handle water. The lifting height refers to the pump's ability to raise water to a certain height. The higher this height, the more powerful the pump needs to be.
4. Pump wheel type: A single-channel wheel is sufficient for clear and lightly charged water. A vortex wheel absorbs impurities in charged water. A chopping wheel is necessary for treating heavily loaded materials.
5. Price and delivery: The price of a sewage pump varies depending on the features and options chosen. It’s important to compare products and consider associated services, such as delivery and warranties.
6. Ease of installation: Some models come in a kit with all the necessary elements for quick and easy installation.
