Something wrong with that pump, it should be able to handle the A/C without a problem. The 9' lift shouldn't be enough to hinder it.
The A/C can't remove 1 gallon a minute of moisture from the air. Make sure there are no kinks in the drain line of the pump.
And eliminating 2' of the lift will increase its pumping ability.
