Abstract
A method of assembling a scroll pump comprises the following steps carried out sequentially; the step of mounting a first bearing means (20) and drive shaft (14) for rotation relative to a housing (12): the step of fastening a first flange portion (48) of a bellows arrangement (34) relative to the housing (12); the step of fastening an orbiting scroll (26) to a second flange portion (56) of the bellows arrangement (34); and the step of fixing a second scroll (28) relative to the housing (12) for co-operation with the orbiting scroll (26). The second flange portion (56) is fastened to the orbiting scroll (26) with fasteners (60) which extend through a through-bore (61) in the orbiting scroll and engage with the second flange portion.
