Can a pulley be used to drive a water pump?
Some manufacturers like Ford and Mazda have driven the pumps with a pulley on the exhaust camshaft. Other manufacturers have decided that the chain on the front of the engine may be a better solution. In the early 1990s, a serpentine belt on the front of the motor typically drove the water pump.

What causes a chain driven water pump to fail?
Another reason why chain-driven water pumps fail is a worn or defective tensioner and guides. Most engines use oil pressure to actuate a tensioner that puts pressure on a guide. If the tensioner fails (typically due to a lack of oil changes), the chain will move around due to centrifugal force acting on the chain.
