Abstract

Un miembro obturador elastómero (10), para uso en una bomba que tiene revestimientos laterales ajustables (38, 40), está estructurado con una pestaña (74, 76) del tipo de fuelle que proporciona y mantiene una obturación hermética entre los elementos (14) envolventes adyacentes de la bomba, ya que los revestimientos laterales (38, 40) están ajustados axialmente para compensar el desgaste y la abrasión de los revestimientos laterales. El miembro de obturación elastómero (10) proporciona una obturación continua entre los elementos (14) envolventes adyacentes, ya que los revestimientos laterales (38, 40) están ajustados axialmente, prolongando de este modo la vida de servicio de los revestimientos laterales (38, 40) y extendiendo el número de horas que la bomba puede estar funcionando antes de que se necesite una sustitución de los revestimientos laterales y de la obturación.
