Abstract

1,255,164. Diaphragm pumps. H. OTT [trading as LEWA HERBERT OTT], Dec. 4, 1968 [Dec. 15, 1967], No. 57699/68. Heading F1A. In a hydraulically actuated diaphragm pump in which the diaphragm 3 consists of at least two individual diaphragms 3a, 3c glued or welded at their edges and having a space between them consisting of chamber 5, which may include an additional slotted diaphragm 3b, and containing a hydraulic fluid and which is connected through a non-return valve 12 to a tank 13; diaphragm fracture or damage is detected by leakage of fluid into tank 13. Three fluid tight and two intermediate diaphragms may be provided.
