Few things can disrupt a construction project like excessive groundwater, which is why dewatering pumps are often required for larger projects. Removing that excess water can help prevent everything from mudslides to equipment failure, but you might find it tough to choose the ideal type of dewatering pump to meet your needs.
The three main options include centrifugal pumps, progressive cavity pumps, and diaphragm pumps. While progressive cavity and diaphragm dewatering pumps can work well in certain situations, most construction project managers will find that centrifugal pumps make the right choice.
Here are just four reasons why.
Centrifugal dewatering pumps use rotating impellers to create enough atmospheric pressure to suck water up through a hose, and this process is excellent for high-flow applications. When you need to move large volumes of water as quickly as possible, centrifugal pumps can make it happen. This is especially important for construction work since you'll want to have excess water removed without delay in order to stay on schedule.
A centrifugal pump benefits from a relatively simple design that utilizes few moving parts. As such, maintenance requirements are minimal and technical issues will be rare. This makes centrifugal dewatering pumps an ideal choice when a pump may need to be used often or even continuously. In fact, centrifugal dewatering pumps can even run dry for limited periods without suffering internal problems. Since any problems with your dewatering pump can produce significant delays and high repair costs, it makes sense to opt for a simple design that isn't likely to cause problems.
The fact centrifugal pumps benefit from such a simple design provides advantages beyond reliability. That simplicity also means centrifugal pumps can be made using many different materials capable of handling a variety of liquids. For lighter-duty work, you can opt for a pump made using plastics or cast iron. If you expect to deal with corrosive materials, you can choose bronze or stainless steel. Additionally, centrifugal pumps are available in a wide range of sizes, so you'll always be able to find one perfectly suited to your project.
Finally, centrifugal dewatering pumps tend to offer far more compact designs than other types of pumps. This makes them a good option if space might be an issue. Since most construction sites are busy places that already contain a lot of heavy-duty equipment, it makes sense to pick a dewatering pump that is going to be easy to fit in.
