Abstract

In a double-diaphragm pump in which non-return valve means (7a, 7b, 7c, 7d) controlling the flow of the fluid being pumped are housed in a centre section (10) between two end sections (2) of the pump body, the centre section (10) comprises two parts which respectively provide two axial end walls (14, 15) of the centre section (10), one of said parts having a portion projecting from its axial end wall and providing said valve seats and one of said parts having an enclosing portion which encloses said axially projecting portion and forms a seal with the other part, said parts being axially separable and the arrangement being such that when the parts are separated, ready access to the valve seats and valve members is provided.
