ABSTRACT:
The outer tubular assembly (4) of the tube pressure filter comprises a cylindrical member (36) and, at each end, an end assembly comprising two annular members (38 and 40) which are releasably secured to the cylindrical member (36) by a split retaining ring (42). The two annular members define a cavity (62) for receiving the lip of a diaphragm (18, FIG. 1). The axially inner annular member (38) defines, with the cylindrical member (36) an annular chamber (56) for receiving fluid under pressure and an annular slot (58) for allowing the fluid to flow between the chamber (56) and the interior of the pressure filter. The split retaining ring (42) engages a groove (52) in the cylindrical member (36), so securing the end assembly to the cylindrical member (36) without the need for welding.
