1. An apparatus having pump components drivable by an external rotary input, said apparatus comprising:
- a housing having an inlet, an outlet, and a passage extending through the housing between the inlet and the outlet;
a tube compressor;
a curved wall surface on the housing which completely circumscribes said tube compressor during storage of the apparatus;
a compressible tube carried by said housing and defining at least a portion of said passage, said tube being between the curved wall surface and the tube compressor and being in an uncompressed state during storage of the apparatus;
means for mounting the tube compressor on the housing for free radial movement relative to the curved wall surface and for rotational movement whereby the tube compressor can be caused to roll along the tube to squeeze the tube in a zone which moves along the tube to thereby pump fluid in the tube, said mounting means serving to position said tube compressor in a neutral position during storage such that said tube is not compressed by said tube compressor during storage; and
means on the tube compressor for use in releasably drivingly coupling the tube compressor to the external rotary input whereby the tube compressor can be rolled along the tube to pump fluid in the tube.

Abstract
An apparatus comprising a housing, a curved wall surface on the housing and a tube compressor carried by the housing. A compressible tube, which defines at least a portion of the passage, is positioned between the curved wall surface and the tube compressor. The tube compressor is mounted on the housing for free radial movement relative to the curved wall surface and for rotational movement. The tube compressor can be releasably drivingly coupled to an external rotary input so that the tube compressor can be rolled along the tube to pump fluid in the tube.
