A solution pumping system includes a compressible pump cassette having front and rear body members, and an elastomeric diaphragm positioned therebetween. The front and rear body members are joined to each other for limited, relative movement, which movement effects compression of the diaphragm. The pump cassette is removably positionable in a pump driver of the system, which can be configured to effect compression of the cassette for use. In this way, the desired compression of the diaphragm during use can be achieved, while avoiding problems associated with compression set or load decay during storage of the cassette prior to use.
