Abstract

BOMBA ANULAR DE DUPLO ESTáGIO, TENDO TUBO COLETOR, CALçOS E SALIêNCIAS DE RECEBIMENTO DE ANéIS "ORING" DO CABEçOTE DO PRIMEIRO E SEGUNDO ESTáGIOS. A presente invenção refere-se a um primeiro cabeçote de uma bomba anular para líquidos que tem uma entrada, uma saída, uma abertura receptora de eixo se estendendo através da mesma, e uma extremidade interna, A extremidade interna inclui uma saliência com uma parede lateral. A saliência é recebida por um corpo de bomba. Um coletor interestágios é amovivelmente acoplado com a bomba sem ser integrado com ou conectado com o corpo da bomba. Um anel "ORING" pode ser localizado entre uma parede lateral da saliência e uma parede lateral interna do corpo.DOUBLE STAGE ANNULAR PUMP, HAVING COLLECTOR PIPE, SHOES AND HEELS FOR THE FIRST AND SECOND STAGES 'HEAD RING. The present invention relates to a first head of an annular liquid pump having an inlet, an outlet, a shaft receiving aperture extending therethrough, and an inner end. The inner end includes a protrusion with a side wall. . The boss is received by a pump body. An interstage manifold is removably coupled to the pump without being integrated with or connected to the pump body. An "ORING" ring may be located between a sidewall of the protrusion and an inner sidewall of the body.
