Patent FR-2528498-A1 (FR)
Title: Well-water pump with double tubular membranes - has membrane channel frames connected through sliding bolts
Inventor: THUREAU PIERRE
IPC: F04B43/06
Filed: 1982-06-14
Abstract: The assembly consists of an actuator (1) located at ground level and a submerged, double-membrane pump (3). The pump has a two-compartment enclosure (11-14) each compartment housing a sealed tubular membrane constrained by a cage or channel (21,22). The latter are connected by sliding bolts, sealed through the division wall (12). The actuator has two fluid filled, flexible membranes (6,7) compressed alternately by an oscillating mechanism (8,29). The actuating fluid is forced alternately into the pump membranes causing an alternate expansion of one membrane and compression of the other through the interconnected channel frames (21,22). A double acting pumping action is thus produced in the two pump chambers.
