There is no pump or other moving parts. It works like this (copy and paste):
Heat is applied to the ammonia and water solution in the generator. (The heat comes from burning gas, propane or kerosene.)
As the mixture reaches the boiling point of ammonia, it flows into the separator.
Ammonia gas flows upward into the condenser, dissipates heat and converts back to a liquid.
The liquid ammonia makes its way to the evaporator where it mixes with hydrogen gas and evaporates, producing cold temperatures inside the refrigerator's cold box.
The ammonia and hydrogen gases flow to the absorber where the water collected in the separator in step No. 2 mixes with the ammonia and hydrogen gases.
The ammonia forms a solution with the water and releases the hydrogen gas, which flows back to the evaporator.
The ammonia-and-water solution flows toward the generator to repeat the cycle.
