John Deere 50,520,530 Original Water Pump. Remanufactured original pump. New bearing.The impeller has a ceramic insert machined into it. This will prevent wearing a groove in the cast impeller causing it to leak. It also will not rust the impeller due to tractors sitting around and not being used. Pump was presure tested.
