Submersible Pumps Eliminate Flood Damage Concerns At LaGuardia Airport
1/23/2014
During Hurricane Sandy, La Guardia Airport’s five stormwater pump stations lost power, resulting in flooding of an estimated 100 million gallons of water. The Port Authority of New York & New Jersey quickly moved up its planned renovations and installed nine axial flow pumps capable of moving large volumes of water at low heads. The propeller-type pumps have motors that are invulnerable to submersion during high-water incidents, improving the airport’s stormwater control, flexibility, and operational efficiency.

WWTP Reaches Clog-Free Operation With Self-Cleaning Impellers
1/22/2014
As with many plants modified for activated sludge treatment, the existing infrastructure at the Adams Field Wastewater Treatment Plant in Little Rock, AR, allowed rags and other debris to clog the impellers of the submersible pumps. One of the plant’s two 15-horsepower pumps was replaced with an 18-horsepower RAS submersible pump with a self-cleaning impeller, virtually eliminating the clogging problem by simply pumping away any debris that reaches the pump intakes.
