What is a Caisson Well Pump?
A type of well that is wider than other wells, reinforced with concrete and has a reinforced ground. They are usually constructed close to water beds. With the help of a caisson well pump, they can meet long-term and continuous clean water needs because they are robustly built. It can also be preferred for collecting surface water.

A Caisson Well Pump is a type of pump used in water wells to draw water from underground sources. It is housed within a caisson, a watertight structure typically sunk into the ground to access water or to create a safe and dry working environment below ground level. Here’s a breakdown:
Key Features:
- Caisson Structure:
- Made of steel, concrete, or other sturdy materials.
- Protects the well shaft and prevents the entry of contaminants.
- Keeps the surrounding soil stable, especially in loose or sandy conditions.
- Pump Mechanism:
- The pump can be submersible (installed underwater inside the well) or jet (installed above ground).
- The choice depends on the well’s depth and water flow requirements.
- Applications:
- Commonly used for municipal water supplies, irrigation, and industrial purposes.
- Ideal for deep wells or wells located in areas with challenging soil conditions.
- Advantages:
- Provides a secure and durable solution for accessing groundwater.
- Helps maintain water quality by isolating the well from external contaminants.
- Operation:
- Water is drawn up through pipes using suction or pressure mechanisms, depending on the pump type.
Caisson wells and their pumps are particularly advantageous in areas where traditional well construction may not be feasible due to loose soil or high water tables.

Caissons: Unveiling the Mystery of Underground Structures
Have you ever wondered what lies beneath the surface in certain construction projects? The answer might be a caisson. But what is a caisson, exactly? In essence, a caisson is a watertight retaining structure used to work on foundations for bridges, dams, or other projects that require excavation below groundwater level. It’s like a giant, hollow box sunk into the earth, allowing workers to safely perform tasks in a dry environment.
Now, where does a caisson sump pump fit into the picture? In some applications, particularly when dealing with persistent water seepage, a pump caisson is utilized. This specialized caisson houses a sump pump system. The pump works tirelessly to remove any water that accumulates within the caisson, ensuring a dry workspace. So, whats a caisson without a good pump? It’s a wet and potentially dangerous environment. The caisson sump pump is crucial for maintaining stability and facilitating efficient construction or maintenance in challenging conditions.

What Should We Consider When Buying?
- -What is the diameter of the well?
Well diameter is important when choosing a pump because of the size information.
- How deep is the well?
Well depth is required for pump selection and motor size is preferred according to the need.
- At how many meters do we reach the water?
In the selection, the place where it reaches the water and the meter from which it will extract the water are necessary in choosing the size.
- How many m3 of water is needed?
The amount of water needed is necessary to select the size of the pump.
- Is the floor of the well concrete or mud?
The ground of the well affects the cleanliness of the water and the meters in which the pump will be immersed.
