Abstract

A pump which may be actuated by compressed air comprises one or more elongate annular pumping chambers X, Y, Z, the or each chamber being defined at its inner periphery by a core 14, at least the surface of which is fluid- impermeable, and at its outer periphery by a flexible fluid-impermeable membrane 15, the said core and the said membrane being interconnected at their ends by annular members 19 defining fluid inlet means and fluid outlet means respectively. <IMAGE>
