Abstract:
A tubephragm pump includes a tubephragm that has a pump head portion that forms a pump chamber, a driving head that holds the tubephragm and expands and contracts the pump chamber by directly pressing and pulling the pump head portion in a direction intersecting with a transfer direction of a transfer fluid, a driving unit that drives the driving head back and forth in a driving direction to expand and contract the pump chamber, and a control unit that controls the driving unit. The tubephragm is in a flat shape with a cross-sectional shape intersecting with the transfer direction of the transfer fluid of the pump chamber having a length in a direction intersecting with the driving direction longer than a length in the driving direction. A pair of liquid contacting surfaces opposing in the driving direction of the pump chamber move while maintaining a parallel state.
