Billet Water Pump Impeller for KSE

The K.S.E. Racing Billet Water Pump Impeller for KSE high-speed water pumps is a precision-engineered aluminum component designed for racing and performance engine cooling systems. Built from billet aluminum stock in a natural finish, this impeller (part number KSD1089) is engineered to deliver consistent flow rates at elevated RPMs, making it essential for motors running sustained high-speed operation where thermal management is critical.

The billet construction process yields a denser, more uniform material structure compared to cast alternatives, resulting in superior durability under pressure cycling and cavitation stress. Aluminum's thermal conductivity supports efficient heat transfer from the cooling medium, while the impeller's hydrodynamic profile is optimized for the high-RPM operating range typical of race-prepped and performance engines. The natural aluminum finish resists corrosion in standard coolant environments and can be anodized or treated for enhanced longevity if desired.

This replacement impeller is specified for KSE water pump assemblies and serves builders and teams who demand reliable, repeatable cooling performance during competition and dyno testing. Whether rebuilding a pump for seasonal maintenance or upgrading an existing cooling circuit, the billet construction and high-speed rating make this component suitable for both naturally aspirated and forced-induction applications. Compact dimensions (4.5 x 1.65 x 4.55 inches) ensure straightforward installation within standard pump housings.
