Graf Water Pumps - All the Graf Water pump parts are pre-tested to evaluate durability, performance and reliability. The bearings undergo a durability test equivalent to nominal lifespan and are then inspected to assess integrity. The mechanical seals are tested in extreme coolant temperature conditions according to predefined cycles. The shape of the water pump impellers is optimized thanks to the use of prototypes on which flow and performance tests are performed. After assembly all the Graf Water Pumps undergo seal tests on units that reject those with leaks above set limits.
