Dewatering is an aspect of almost all construction projects. Examples include lowering the water table prior to excavation, removing standing water or planning for rainfall. Overlooking or underestimating dewatering increases your costs and causes delays in construction.
Selecting the right construction dewatering pump can have huge implications on project success. Many construction project managers underestimate the importance of selecting the right pump. Premature pump wear or unexpected failure can significantly increase project expenses and delay project schedules.
The best pump choice for construction dewatering is a submersible pump. Some project managers use self-priming pumps because they are more portable. However, a long suction hose going into your self-priming pump causes frequent loss of prime and stalled pumps. Also, self-priming pumps tend to only dewater solids in the pit rather than remove them.
Coal-mining operators rely on submersible slurry pumps to handle punishing conditions. Among the harshest environments for pumps, coal slurry quickly abrades their metal components. Inferior pumps lower mine output and increase operating costs. How can you extend pump lifespan and raise job productivity? Below we discuss the most cost-effective wastewater pumping equipment for coal-mining applications.Coal-Mining Pump Issues That Increase Your Costs
There are three coal-mining issues that plague slurry pumps and shorten their lifespans.Abrasive Solids
Coal itself is a highly abrasive material. A coal slurry is a muddy, acidic mixture of water, coal chunks, coal fines, dust, dirt and rocks. Coal fines are coal particle size usually less than one-sixteenth of an inch. These are especially abrasive to a pump’s internal components. These materials combined wreak internal havoc on pumps, causing clogs and failures.
