Abstract
Methods and systems are provided for a coolant pump. In one example, the coolant pump may be a dual-volute coolant pump with an impeller driving circulation of coolant through the pump and a seal disposed around a shaft of the impeller. A set of anti-vortex structures may be arranged within an inner chamber of the pump, the structures generating a pressure differential in the inner chamber that drives a cross-flow of coolant, thereby convectively cooling the seal.
