PRW high flow aluminum pumps are engineered to deliver a volumetrically increased water flow that significantly improves cooling system demands of circle track and endurance racing. These pumps are sealed by the ceramic coating that blocks excessive heat radiation rather than absorbing it), thus preserving and extending the pumps service life. This coating also provides superior corrosion resistance and rust protection. The low-pressure injected aluminum alloy pump bodies feature a precision cast-iron impeller design and pressure-balance water passages to equalize flow and minimize engine hot spots at any speed. Other features include steel hubs and heavy duty, shielded-sealed roller ball bearings.
