They're very different things but most good water pumps are rated for 50,000 hours or around 5 years continuous use. I don't know of many parts of a car that would like running for 5 years straight.
My car doesn't have that much actual running time per year and I think the average is fairly low. 50,000 hours at an average of 80kmh is 4,000,000km or over 2.5 million miles. I don't think that is possible for a car.
