How about (for a good pump) - 'One that circulates sufficient coolant for the engine under all conditions'? BTW did you find bits of the old impeller? Where did they go? When the air is cool and the thermostat fully open your water pump was able to keep up. Had the air been hotter and running the air con I guess it would boil, given time.
