ABSTRACT:
A configuration of pumps is presented which eliminates problems of leakage, particularly leakage from pumps handling toxic or other fluids which might pollute the atmosphere. The leak contained pumps prevent leakage to the environment and/or pump motors upon the failure of pump seals as a result of wear or other reasons by providing confinement of any potential fluid leakage between the pump and motor, said leakage being channeled to a collector sensor associated with the pump which activates introduction of additional inert gas to the motor chamber and leakage confinement zone to provide motivational pressure to the leakage fluid as needed, the leakage fluid and inert gas being transferred to a separator after passing through the sensor.
