Abstract

"ESTATOR PARA BOMBA DE PARAFUSO EXCêNTRICO". A presente invenção refere-se a um estator para bombas de parafuso excêntrico, compreendendo um corpo oco (1), de material plástico, o qual, no lado externo, está provido com um invólucro, sendo que o invólucro compreende vários segmentos (4a, 4b, 4c), ligados uns com os outros, estendendo-se em direção longitudinal. As superfícies dos segmentos (4), são dispostas em um plano, de tal maneira que pela ligação destas forma-se um invólucro poligonal fechado. O lado externo do corpo oco (1), de material plástico, está cercado em uma forma poligonal, possibilitando assim a obtenção de seu fecho pela forma com o invólucro.
