Abstract

501,828. Centrifugal pumps. BRITISH THOMSON-HOUSTON CO., Ltd. May 26, 1937, No. 14627. Void. Convention date, May 26, 1936. [Class 110 (i)] A centrifugal ptunp, such as a petrol pump, includes a positive-displacement priming-pump with rotor 35 mounted on the impeller shaft 18, a common dividing wall 41 separating the impeller 32 from the rotor 35. The annular discharge-chamber 45 substantially surrounds the priming-pump to reduce the transmission of noise when filled with liquid. The inlet 38 to the priming-pump communicates by a channe] 51 with an upper point of chamber 45 to remove gases therefrom, the discharge opening for liquid 40 leading from a lower part of chamber 45. Fluid from chamber 45 may enter the priming-pump at high pressure in which case this pump acts as a motor and reduces the power required of the electric motor. The inlet 44 and outlets 49, 55 are connected to the lower part of the pump casing. The diffuser scroll 46 may have an upper plane surface to prevent the formation of gas pockets.
