The Amarex KRT jacket-cooled wastewater pump from KSB has a completely sealed, closed-loop cooling system to keep cooling passages free of debris. The cooling liquid inside the jacket is an environmentally safe propylene glycol and water mix. The 38/62 antifreeze mixture provides pump protection down to -4 degrees F. An impeller inside the closed-loop system circulates the antifreeze mixture so that it constantly flows around the motor, gathering heat, then over a heat exchanger, which dissipates the heat. The system is completely sealed against the pumped media as well as the air-filled motor housing. It can be installed in a variety of configurations to accommodate the requirements of any wastewater application. Monitoring sensors are teleservice-enabled to permit remote monitoring, and the epoxy sealed cable entry points provide safe operation, even if a cable is damaged or cut below the water level. 804/222-1818;
