Closed loop cooling system featured in the dry pit submersible pump eliminates the problems and expense of thermal overload, debris entrapment, and frequent maintenance experienced with pumped liquid- or fan-cooled pumps. Unlike other pump cooling systems that circulate the pumped liquid containing various impurities through the sewage cooling jacket, the dry submersible pumps provide a clean, self-contained, closed-loop cooling system that circulates a clean, all-temperature glycol/water mixture around the motor.
