Most water pump options for your Cummins on the market today are constructed of a cast iron housing and plastic impeller. Yes, you read that correctly, plastic impeller. These water pumps are not only un-reliable but will make you cringe when you are installing. Replace your water pump in your Cummins for the last time with the BulletProof Diesel Billet Cummins Water Pump.

The BulletProof Diesel Billet Aluminum Water Pump is designed for maximum durability and efficiency. The stronger, metal impeller resists cracking along the hub helping to prevent impeller failures, overheating, and expensive repairs. The metal impeller is also stiffer and stronger, therefore less likely to flex under heavy loads, which could help prevent cavitation and erosion within the front cover. The lightweight all aluminum drive pulley minimizes parasitic loss and because of the cooling fin design, helps to cool the bearing under even the most extreme conditions. It also looks really cool! Lastly, the bearings in this pump constructed from a much larger, robust roller and ball bearing design that offers superior durability and longevity as compared to the factory unit.
