A diaphragm pump (10) including a body (11) that provides a pair of opposed pump chambers (12) and (13). Mounted in the body (11) is a piston assembly (14) providing a pair of pistons (15) joined by a transverse piston rod (16) so that the pistons (15) are caused to reciprocate in unison linearly in the direction (17) along the axis (18).
