3 Essential Factors to Consider When Selecting the Ideal Dewatering Pump

You might need to dewater your construction site for various reasons. Flooding is the primary issue caused by high-water tables, torrential rains, damaged drainage pipes or melting ice. Therefore, it's important to get rid of the excess water to keep your site safe and maintain its structural integrity. 

While industrial pumps help perform dewatering functions, not all function the same. Every pump has features and capabilities that lend themselves to specific applications. It's crucial to pick the most fitting dewatering pump for your unique requirements to achieve the desired results. 

This post discusses three essential factors to consider when shopping for an ideal dewatering pump for your construction project. 

The Fluid's Percent Solid 

Typically, this is the amount of solid content in the groundwater you intend to dewater. When in abundance, select a pump with excellent resistance to abrasive wear. The degree of abrasive wear typically defines the number of times you should service your dewatering pump. 

For instance, opting for an end suction pump means you'll require constant system maintenance due to damage caused by abrasion. On the other hand, picking a trash pump would be ideal since it can withstand large quantities of mud, silt and other solid substances. Therefore, during your selection process, remember that pumps that demand extensive maintenance might cost you more in the long run. 

The Depth of the Underground Sump

Another essential factor when choosing your dewatering pumps is the depth of the underground sump. That means you should consider the pressure your pump must create to perform the dewatering process efficiently. 

Generally, centrifugal dewatering pumps are an economical solution for up to a few hundred feet. Above this depth, you might require staging your centrifugal pumps to attain the necessary pressure. Consequently, this impacts piping complexity, abrasive wear and overall maintenance. On the other hand, if the vertical pumping distance is above a thousand feet, you might need to set up several stages besides observing other vital factors. 

The Pump's Portability and Size

Finally, the current manufacturing industry is gradually moving away from large, immobile pumps to small, portable dewatering pumps. It's crucial to select multipurpose pumps with built-in features that enhance their safety and portability. 

For example, choose dewatering pumps with integrated lifting and trailer capabilities. Thus, before buying your dewatering pump, ask about extra safety options that promote the pump's portability on construction sites when required. Portability is a critical element when selecting dewatering pumps for your construction site.
