Abstract: 590,516. Centrifugal separators. THOMPSON PRODUCTS, Inc. Dec. 21, 1944, No. 25652. Convention date, Nov. 29, 1943. [Class 23] [Also in Group XXVI] A submerged pump, particularly for pumping aircraft fuel, has an open-ended barrel-shaped rotor 40 with pumping vanes between central flanges 42, 43. Vanes 45 project inwardly from the barrel-shaped part and cause the liquid within the rotor to rotate. A screw fan 46 is carried by the rotor. The whole is surrounded by a gauze cylinder 31 and the pump is driven by an electric motor 10. The liquid passing through the central aperture 32a is agitated by the screw fan 46 and some released vapour passes outwards below the pump casing 20 and through the gauze back to the tank. The liquid passes upwards into the barrel-shaped rotor, which has a flared entry 40a and is caused by the vanes 45, to whirl round with the rotor. This moves the remaining vapour inwards and it rises through the open upper end of the rotor and escapes through the gauze to the tank. The liquid passes to the vaned passage between the flanges 42, 43 and is delivered to the pressure chamber 22 whence it passes through a port 26 to the supply pipe 27.
