Abstract
The present invention is directed to a gas pressure driven liquid pump having a pump body, liquid inlet, liquid outlet, a pair of pump mechanisms each including a float, and a baffle within the pump body creating two chambers within the pump body. A separate pump mechanism is configured to operate in the respective chambers. The baffle includes a void located below a low liquid level position so that a liquid seal is maintained between the two chambers. As the pump body fills with liquid condensate, a high liquid level position will trigger the respective pump mechanisms to allow motive gas into the chambers, pumping the liquid out of the pump body.
