Abstract

Systems and methods are provided for monitoring and dynamically adjusting the operation of a pneumatic pump. The pump is controlled to alternately apply an initial negative pressure and an initial positive pressure to a flexible diaphragm of a pump chamber to draw fluid into the chamber and then convey the fluid from the chamber. The initial pressures are selected to be the minimum negative pressure at which the chamber is expected to completely fill during application of negative pressure to the diaphragm for an inflow duration and the minimum positive pressure at which the chamber is expected to completely empty during application of positive pressure to the diaphragm for an outflow duration. If a complete fill and/or a complete empty is not achieved, then the appropriate initial pressure is increased in order to arrive at the minimum pressures at which a complete fill and empty are actually achieved.
