Abstract
1386385 Rotary positive-displacement machines SUMITOMO SHIPBUILDING & MACHINERY CO Ltd 16 March 1973 12826/73 Heading F1F An internally-meshing screw pump has a corrosion-resistant stator assembly 7 comprising a rigid casing 9 with its ends embedded in frustoconic rims 11 of a flexible and resilient member 10 made of e.g. rubber. The assembly is clamped between annular flanges 4, 6 of intake and discharge members 1, 5 by rods 8.
