A FLUID PRESSURE DRIVEN PUMPING SYSTEM

摘要

This invention concerns a pumping system (1) for transferring fluid from a source (22) to a storage or usage point (7) against a head pressure and without the need for a power source at the fluid source (22). In a preferred form the pumping system (1) has reciprocating drive means (5) controlled by a valve means (3) connected to a pressure supply (2). The drive means (22) drives a driven means (6) in fluid communication with a fluid source (22) and adapted to pump the fluid source (22) to a storage or usage site (7). The ratio of volumes of drive to driven means is adjustable to enable efficient use of the pump at different supply pressures and for different volume or pressure output requirements.
