Abstract
arranjo invertido da lacuna do lado anular para uma bomba centrífuga. vários aspectos da divulgação são direcionados a fornecer estruturas que definem uma lacuna radial entre um impulsor e um elemento de invólucro da bomba que facilita a minimização do movimento de fluido para a lacuna radial de uma maneira que diminui o impacto e a consequente degradação da superfície interna do elemento de invólucro da bomba pelo movimento de particulados abrasivos para fora da lacuna radial, que é realizado fornecendo um arranjo de entrada de sucção de um impulsor e elemento de invólucro da bomba que são angulados do olhal do impulsor até a periferia externa do impulsor em um direção para longe da proteção traseira ou lado de acionamento do impulsor e em direção a uma primeira extremidade do invólucro da bomba no qual o fluido é introduzido no invólucro da bomba.
