Pumping around the clock at 10,000 gpm, two 94hp submersible, portable dewatering pumps manufactured by Pumpex, Inc. of Somerville, N.J., drained turbulent, overflowing stormwater to save a limestone quarry from extensive equipment damages and potential profit loss caused by severe flooding.
Typical agricultural, domestic and municipal systems are excellent applications for these motors. Unfortunately, these motors often are used in applications that unknowingly exceed the design criteria of the motors.
The intake system that will draw cooling makeup water from the Kaskaskia River for the $250-million Holland energy plant in Shelby County, Illinois, was designed to balance construction cost imperatives against the river’s variable flow, regulatory requirements and the owner’s operating preferences. The result is a state-of-the-art vital element for the gas-fired, combined cycle plant. As more and more closed-cycle plants are proposed, the concepts that Parsons applied along the Kaskaskia River may provide a good starting point on the drawing boards.
