A pumping system includes a pump and a motor operatively coupled to the pump. The motor is configured to drive the pump to increase a speed of expelling spraying fluid in response to the pumping system ascending to be above a threshold altitude and to decrease the speed of expelling the spraying fluid in response to the pumping system descending to be below the threshold altitude.
