143275D WATER PUMP (348/MOND T) REPRO
WATER PUMP REPRODUCTION
From the manufactuer "The impeller is a proprietary design eliminating stock design deficiencies which see inherent cavitation (little or no coolant flow) issues especially above 5000rpm. Bearing quality and longevity was tested for multiple hundreds of hours, both in and out of test bed cars, at varying side loads above that of its intended use as well as pressure and heat loads to simulate the most grueling conditions. As an added protection, the casting is anodized to help eliminate moisture from affecting or entering the bearing area."
