  • Casing of an eccentric worm pump designed to burst at preselected pressure
    Patent number: 5318416
    Abstract: A stator jacket (12) and a stator lining (22) of elastomeric material together form a tubular pump stator (10) the ends (20) of which are connected to a connecting piece (36) of a casing portion (32, 34) each. The stator jacket (12) has at least one parting area (14) extending throughout its length. This and the region of the stator lining (22) located radially inside thereof as well as the junctions of the connecting pieces (36) with the stator jacket (12) are designed such that the pump stator (10) will burst in at least one parting area (14, 16) when a predetermined positive internal pressure is exceeded. This provides pressure relief before a risk of explosion can develop when explosives are being conveyed.
