Abstract

A membrane pump as in the main patent, with a double membrane consisting of a main membrane (4) spaced from a safety membrane (1) housed under a cap containing the discharge valve has the space between filed with a fluid lubricant. The diaphragms are of the roll type, so that the space (16) is in the form of a loop. The piston rod (9) which is attached at the top to the centre of the two diaphragms is guided by a tube (11) formed by the interior of the casing and hangs vertically at the centre, and this rod terminates at the bottom in a bulbous portion with a slot (12) in which reciprocates the drive pin (14) as it rotates eccentrically.
