Sealed, non-clogging, long-wearing pump is designed to handle extended and intermittent periods of pumping. Solids, fibrous material, leaves, and other material easily pas through the pump without resulting in pump failure due to heat generation. Pump features SmartSeal, a cartridge mechanical seal assembly that simplifies maintenance. Integrated cooling chamber eliminates dependency on external fans or cooling systems.
