Speedway Motors 91015491 Details

From top to bottom, these mechanical pumps are designed for greater performance and reliability. They feature an 8-blade, cast aluminum anti-cavitation impeller. Its 5/8" shaft is driven by heavy-duty bearings and seals, and the crank hub is 1/2" thick for added strength. These Water pumps are cast from lightweight A356 aluminum and heat-treated to T6 hardness. This not only provides strength, but aluminum works to manage heat far better than cast iron.
