ABSTRACT:
A fluid pump which uses a motive fluid for pumping liquid or gaseous fluids by use of a fluid inlet, a fluid exchange chamber, and a fluid exhaust means operates as follows: A fluid which is to be pumped is introduced into a fluid exchange chamber. The exchange chamber then isolates itself from the fluid source. Now a motive fluid is introduced to the exchange chamber. The fluid which is to be pumped is carried away from its intended use while the motive fluid displaces the previously existing fluid in the exchange chamber. The exchange chamber is then exhausted of its motive fluid contents and more fluid which is to be pumped, is once again introduced to the exchange chamber to repeat the cycle.
